A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula

his paper’s intended contribution, in terms of providing an additional angle in the existing Bus Rapid Transit (BRT) state-of-the-art knowledge spectrum, is a dual one. On the one hand, it provides a detailed description of the mode, re-deining BRT as an overall concept by identifying, discussing, and categorizing in a systematic way its strengths and its weaknesses in comparison with rail-based solutions and conventional bus services. On the other hand, it presents in detail a number of selected scheme-oriented applications from around the world, looking into some of the basic ingredients behind BRT’s success (or failure) stories. his is a scientiic efort that could inform the reader about the current status of BRT internationally and about the challenges and opportunities that exist when trying to materialize BRT’s potential as an efective urban passenger solution that could challenge the merits of more conventional mass-transit options. Introducing Bus Rapid Transit Bus Rapid Transit (BRT) is a modern breed of urban passenger transportation with a consistently growing global importance due to evidence of an ability to implement mass transportation capacity quickly and at a low-to-moderate cost (Deng and Nelson 2011). Perhaps the most complete and focus-driven deinition of what BRT intends to be is the one addressing it “as a rubber-tyred rapid transit service that combines stations, vehicles, running ways, a lexible operating plan, and technology into a high quality, customer focused service that is frequent, fast, reliable, comfortable and cost eicient” (Canadian Urban Transit Association 2004). More speciically, BRT refers to schemes that apply rail-like infrastructure and operations to bus systems in expectation of oferings that can include high service levels, segregated rights-of-way, station-like platforms, high-quality amenities, and intelligent transport systems for a fraction of the cost of ixed rail (Currie and Delbosc 2011). his cautious phrasing means that BRT “does not necessarily represent transformation as such, but a means to achieve transformation” (Mejia-Dugand et al. 2013). A combination of infrastructure A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 2 and service-oriented elements that, in principle, mean to bridge together the best that light rail and buses have to ofer is the prerequisite to forming mass transit systems capable of responding to rapidly-changing mobility needs with a strong positive identity that evokes to a unique image (Levinson et al. 2003). BRT applications are designed to be appropriate to the markets they serve and their physical surroundings, and they can be incrementally implemented in a variety of settings and types. Because of the inherent lexibility advantages of rubber-tired buses—e.g., unlike rail systems, the same vehicle that functions as a line-haul carrier also can morph into a neighborhood feeder—BRT also is suited for many lower-density areas (Cervero and Kang 2011). However, the vast potential of BRT could be used at its maximum rate in congested urban environments where adequate mass transit services could not be provided to road users by (or solely by) more expensive modal options such as light rail or metro. BRT, thus, is a homogeneous system of facilities, services, and amenities that has the potential to become an alternative far more competitive to car-oriented mobility than conventional buses, to the degree that it could redeine the very identity of a city. A BRT system is composed of the following ingredients: • Vehicles, which not only contribute signiicantly to BRT’s image and identity, but also play a strong role in achieving measurable performance success (Zimmerman and Levinson 2004) • Stops, stations, terminals, and corridors, which deine the system’s area of operation • A wide variety of rights-of-way, including bus priority in signalized intersections, dedicated lanes on surface streets, and, more importantly, special BRT busways completely separated from road traffic; BRT routes can be operated almost anywhere—on abandoned rail lines, within a highway median, or on city streets (Jarzab et al. 2002) • Pre-board fare collection, to disengage ticketing from the on-board user experience and to provide a hypothecation mechanism for the system’s long term viability • he use of information and communication technologies, to improve the quality of the services provided in terms of customer convenience, speed, reliability, integration, and safety • All-day service that, according to Levinson et al. (2003), should operate at least 16 hours per day with peak headways of 10 minutes or less • Brand identity, consisting of perceptual constructs substantiated by the strategic deployment, placement, and management of communication elements that allow people to recognize the unique qualities of a speciic BRT system; these include visual and nominal identiiers (e.g., system name and logo), a color palette, and long-term strategic marketing and advertising plans (Hess and Bitterman 2008) For the economy of the overall transport system of a city that employs BRT, some of the infrastructure facilities (e.g., busways and stationary settings) could be shared with light A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 3 rail transit systems (with no loss of performance to either). In other instances, BRT can allow conventional bus services to access certain key sections of its infrastructure, allowing for bus-based service integration (Deng and Nelson 2011). BRT systems also can operate in mixed traic low when physical, traic, and/or environmental factors preclude bus lanes or busways from being implemented—something that could lead to decreased bus speeds and service reliability and be a setback for the system’s image. However, there are serious trade-ofs with implementing BRT in mixed traic low; advantages include low costs and fast implementation with a minimum of construction (Miller 2009). herefore, the amount of dedicated runway for a BRT system is a strategic decision that depends on the city hosting the scheme and the city’s unique geographical, socio-economic, and transport-related characteristics. BRT, nonetheless, is a very demanding transport option that could change the balance of a whole transport network within a city. his is because BRT would re-orient signiicantly something as limited and precious as road space provision in favor of bus services. his obviously will impact the rest of the road traic in a severe way in case a decisive modal shift would not be achieved. It should be noted that BRT is not suitable for every city. here are population and topological criteria and thresholds that justify the implementation and the magnitude of such a scheme. BRT systems have been approached from an institutional perspective (Filipe and Macario 2013; Lámbarry Vilchis et al. 2010), a social perspective (Delmelle and Casas 2012; Lin and Wu 2007), an economic perspective (Cervero and Kang 2011; Hensher and Golob 2008; Lindau et al. 2008), an urban planning perspective (Gómez 2004), an environmental perspective (Wöhrnschimmel et al. 2008), and a technical perspective (Hensher and Golob 2008; Hidalgo et al. 2012). All these authors agree that the BRT concept could be a feasible solution for many cities’ mobility problems and, furthermore, that “there is a lack of studies analyzing the connection among the implementing venues, the transmission of ideas from one to the other, and the impact that incremental improvements have had on the geographical expansion of the concept” (Mejia-Dugand et al. 2013). hus, any work concentrating on such issues could be a timely and meaningful process adding to the existing BRT knowledge. The Advantages of BRT BRT has been widely regarded as ‘‘one of the most wide-spread urban public transportation revolutions’’ of recent decades (Jiang et al. 2012; Levinson et al. 2003). his is because BRT is a mass transit choice with considerable advantages in terms of its implementation merits but also because of its vast potential to eventually beneit in a variety of ways the urban environment for which it has been chosen. Wright and Hook (2007) and Hensher (1999) support the view that BRT is a transport mode rapidly expanding around the world because of its 1) low cost, 2) operating lexibility, 3) rapid implementation, and 4) high performance (i.e., reliability/speed) and impact (i.e., user satisfaction/environmental beneits). Based on a study by the Canadian Urban Transit Association (2004), Hensher and Golob (2008) also report as BRT advantages over other mass transit systems the potential for greater patronage and higher capacities, the possibility of incremental implementation, and the induction of land use changes. However, it has been well documented by A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 4 international experience, thus far, that all these advantages are not necessarily true for every BRT case (Filipe and Macario 2013). he irst signiicant advantage of BRT over rail-based transit options is that it needs considerably lower start-up capital investment while operational costs are moderate (Badami and Haider 2007; Campbell 2009; Hensher and Golob 2008). System costs are a fraction of those of comparable rail systems (Currie and Delbosc 2011; Hidalgo and Gutierrez 2013). Hodson et al. (2013) reported that the main antagonists of BRT, which are light rail systems when compared to bus-oriented schemes in purely economic terms, were found to be: • too costly • poor in terms of inancial performance • in need of signiicant local funding in addition to central government funding to become a reality Figure 1 shows the capital costs per kilometer for selected BRT corridors around the globe. hese costs range from the very moderate $1.4 million per kilometer for the scheme in Jakarta to Bogotá’s $12.5 million per kilometer. Rail systems with similar capacities cost 3 to 10 times more (Hensher 1999; Wright and Hook 2007). FIGURE 1. Capital costs per kilometer for selected BRT systems Source: Hidalgo and Carrigan 2010 he system in Bogotá is considerably more expensive because it includes dual lanes, large stationary facilities, and some non-grade intersections, as well as a large leet of articulated and bi-articulated buses, to provide for very high capacity and high commercial speeds (Hidalgo and Gutierrez 2013). 1 hese costs have not been adjusted to relect inlation since the time of construction, the diferences in labor costs in diferent regions of the world, and the diferences in the nature and extent of planning studies required in various countries because BRT-related expenditure igures are extremely di cult to locate in a form that could be treated accordingly. Rather, these costs are indicative numbers given by the operators but could nonetheless allow rough comparisons between schemes. A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 5 Overall, accessing information about BRT costs is neither an easy nor a straightforward task. In many cases, capital costs for speciic BRT applications are fully integrated in much broader transport improvement packages, and identifying the speciic BRT-related igures is near to impossible. For instance, the TranSantiago project has three main components: the development of a BRT network, the expansion of the existing metro system, and the integration across all transit modes in the city. he initial conceptual framework, estimated at $250 million, was later revised to incorporate an extensive expansion of the metro network with total capital costs of almost $2.5 billion. No speciic information solely related to the TranSantiago BRT framework per se is available. Compared with other forms of mass transit, BRT systems are more lexible. he fact that BRT systems have the potential to use the same operating infrastructure that could have been already in place for light rail transit systems and, at the same time, allow conventional bus services to access certain BRT infrastructure sections to facilitate interconnection and performance enhancement (Deng and Nelson 2011) underlines the interoperability dynamics of this mode. Because BRT vehicles are rubber-tired, they can operate in a wide range of environments without forcing transfers or requiring expensive running way construction over the entire range of their operation. hrough this lexibility, BRT can serve a geographic range much wider than that in which dedicated BRT guideways do exist (Levinson et al. 2002). BRT also may be implemented in combination with a variety of travel demand management measures, such as congestion charging or traic calming. Moreover, BRT can be more adaptable to deal with changing travel patterns and is faster to build than any rail-based scheme. he capability of BRT to be implemented rapidly make this type of system attractive to political leaders willing to complete systems before the next election cycle (Hidalgo and Carrigan 2010). In comparison, the planning timescales and consultation processes for rail-based systems are excessively long, and this is a key reason that a number of these schemes have failed already in the planning stages (Hodgson et al. 2013). When there was a clear BRT vision by a local champion or any other political leader, planning for implementation received priority and development cycles were short, at least for the initial phases of project implementation (Hidalgo et al., 2007). For instance, the city of Guadalajara, Mexico, completed a high-quality corridor 16 km long for 125,000 passengers per day in only 2 years from idea to implementation (Hidalgo et al. 2010). he successes of BRT in Curitiba, Bogotá, Guangzhou, Istanbul, and elsewhere also are helping decisionmakers in developing cities to adopt BRT concepts, although implementation in developed countries has been slower than elsewhere due to preferences of planners and decisionmakers for rail systems and also due to compliance with planning and funding regulations, including extensive public participation processes (Hidalgo and Gutierrez 2013). Case studies summarized by Levinson et al. (2003) and Wright and Hook (2007) suggested that BRT could be the most cost-efective way of providing a high-performance public transit. he main indicators of performance of a BRT scheme are commercial speed, capacity, and productivity (Hidalgo and Gutierrez 2013). he qualities represented by these indicators are supported by special design features that BRT schemes ofer. hese operational features that can deine the individual quality and performance potential of any local BRT application are described by the BRT Standard, a comparison tool meant A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 6 to assign points to BRT systems according to their serviceability. High points mean that a system is in line with international BRT best practice. he assessed aspects that are being considered in the latest BRT Standard designed from the Institute for Transportation and Development Policy (ITDP 2014) include: • BRT basics (dedicated right-of-way, busway alignment, of-board fare collection, intersection treatment, platform-level boarding) • Service planning (multiple routes, express/limited/local services, control center, located in top 10 corridors, demand proile, hours of operations, multi-corridor network) • Infrastructure (passing lanes, bus emissions minimization, stations set back from intersections, center stations, pavement quality) • Stations (distance between stations, safe and comfortable stations, number of doors on bus, docking bays and sub-stops, sliding doors in BRT stations) • Communications (branding, passenger information) • Access and integration (universal access, integration with other public transport, pedestrian access, secure bicycle parking, bicycle lanes, bicycle-sharing integration) Point deduction also exists that penalize BRT schemes for poor performance in commercial speeds, service capacity, lack of enforcement of right-of-way, signiicant gap between bus loor and station platform, overcrowding, poor infrastructure maintenance, and lowpeak and of-peak frequencies (ITDP 2014). Regarding BRT transport-related impacts, most systems have showed better performance than the bus operations they replaced regarding passenger demand, user satisfaction, travel time, and reliability (Diaz and Hinebaugh 2009; Gutierrez 2010; Wright and Hook 2007). Currie and Delbosc (2011) report that BRT technologies not only improve service design compared to conventional bus services but could potentially act as door openers to increased ridership because of: • their higher frequency and longer operating hours services • their priority systems, which are known to reduce journey times and improve service reliability • their better-deined network/corridors, branding, and provision of new technology information systems to improve the ease of understanding the system An additional, positive impact related to BRT systems, which has been documented by international practice, is the improvement of environmental conditions in terms of air quality, noise reduction, and energy consumption; also, externalities such as traic accidents have been reduced considerably. Moreover, when looking at the broader picture on a longer-term basis, one could suggest that some BRT projects, and especially those that have received signiicant capital investments, may have the potential to bring broader efects on urban economic, social, and environmental development (Deng and Nelson A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 7 2013) or at least deliver to the cities hosting them improved and more aesthetically-pleasing urban environments in which their societies can live. It is arguable that BRT systems have been considered catalysts for land development in cities, such as Curitiba, Ottawa, Guadalajara, Guangzhou, and, to a lesser degree, Istanbul (Deng and Nelson 2011). Since proximity to mass transit can greatly save time and money costs of commuting, properties near transport facilities generally become desirable for new development or re-development. As reported by Deng and Nelson (2011), there is a growing body of evidence suggesting that BRT systems increase land values and, in some cases, successfully promote high-density residential, oice, and commercial land use. Perk et al. (2013) report, for example, that the BRT stations located along Washington Street in Boston, where the Silver Line BRT operates, had a considerable impact on the rise in property market values, quite similar to that of light rail transit projects. Also, a detailed analysis on the impact of BRT on residential rents provided evidence showing that accessibility to BRT stations is associated with high value of residential properties (Rodríguez and Targa 2004). The Problems with BRT BRT is connected to a complex set of actors and networks within the social and technical dimensions of the city (Mejia-Dugand et al. 2013) and, thus, it is a system that could be di cult to implement and operate in a lawless manner. Filipe and Macario (2013) report that neither are all the advantages of BRT over other public transport modes always true, nor are the stories of implementing BRT systems always successful ones. here are reports of BRT systems that fail to fulill their objectives and have produced costly, in societal terms, side-efects—for example, the TranSantiago BRT system (in Chile) and its initial implementation. he system’s performance (even now), belying expectations, has been rather dismal, making it a traumatic process for the whole of Chile, to the extent that taboo policy discussions such as nationalizing or subsidizing the public transport of the country became mainstream (Muñoz and Gschwender 2008). BRT systems do not have a single meaning and image; on the contrary, they relect a broad spectrum of applications, spanning from supporting mechanisms that simply provide infrastructure or marketing improvements to existing bus services operating on mixed traic to totally segregated systems. here is a need, thus, to reine the deinition of BRT and BRT-like systems and create categories based on objective performance measures to improve the understanding among planners and decisionmakers (Hidalgo and Gutierrez, 2013). Notwithstanding the growing evidence that BRT could serve, if well-planned and well-executed, as a viable transport “savior,” pro-rail attitudes are still dominant in the public debate regarding best public transportation practice. BRT systems are still often regarded as “second best to rail-based alternatives,” even if this is not justiied by an explicit evaluation analysis (Finn et al. 2011; Gutierrez 2010; Hensher 1999). Despite the growing acceptance that BRT is a time-eicient mode to implement in urban environments that face rapidly-growing mobility needs (Badami and Haider 2007; Hensher and Golob 2008), especially in comparison with ixed rail schemes, the political economy is often favorable to those candidates ofering rail alternatives as part of their A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 8 proposals in electoral debates (Hidalgo and Gutierrez 2013). BRT is, aside from the evidence provided to the contrary by Deng and Nelson (2011), still considered inadequate to foster urban development, and planners often cite this as a fact (Hidalgo and Gutierrez 2013). his is because the lexibility that enables BRT to be implemented in a wide range of environments—one of the system’s main advantages—is also one of its weaknesses since a bus service is generally perceived as being less permanent than a rail service. Local decisionmakers and transport planners may, based on this very reason, question its ability to stimulate land development. However, there is insuicient evidence, especially in developed countries, to prove that development is favored by rail over high-quality bus systems (Hidalgo and Gutierrez 2013). In addition, the fact that BRT is being prioritized over any other road-based transport mode is perceived negatively by car users, who tend to think that road space is reduced, even though, at least in theory, road capacity means to be increased signiicantly. he fact that BRT is cheaper to implement than a rail system does not mean that this is not a capital-intensive system (Deng and Nelson 2011). On the contrary, BRT is far more expensive than any conventional bus system that lacks sophisticated design features and the need for dedicated road space. Actually, funding for some cities that introduced BRT in the past was so scarce that the cities needed to rely on donations, budget allocations from the national governments, and loans. he process of applying for funding could be time-consuming as well, reducing the time window for the actual project implementation (Hidalgo et al. 2007). In addition, several BRT systems in developing countries sufer problems such as the following (see also Hidalgo and Gutierrez 2013; Hidalgo and Carrigan 2010; Hidalgo et al. 2007): • Rushed implementation – several components could be incomplete at the time of commissioning, but gradual improvement over time has been observed • Tight financial planning – systems usually do not receive operational subsidies; there are exceptions, however, such as TranSantiago • Very high vehicle occupancy levels – six to seven standees per m, which is quite frequent nowadays and can make the user experience unpleasant • Early deterioration of infrastructure – lack of road surface reinforcement or problems in design and construction result in maintenance issues • Delayed implementation of fare collection systems – often requiring longer timetables than initially expected and very tight supervision • Poor communication during disruptions caused by construction – can erode public support for the project, and insufficient user information and education prior to the system launch can lead to chaotic conditions or even protests (Carrigan et al. 2011) • Integration deficiencies – for instance, in any urban transit system, the walking catchment area tends to be particularly important since walking is typically the primary access mode for urban stations (Hsiao et al. 1997); nonetheless, the reality is A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 9 that accessing BRT stations is not as easy or safe as it should have been (unpublished research by the authors and some of their students shows that providing better pedestrian safety is a signiicant issue for some BRT applications in China)—this creates a serious integration issue that could adversely inluence ridership numbers hese problems are associated with inancial restrictions and institutional constraints, rather than intrinsic issues of BRT system concepts. Actually, many of them are local problems with unique topological character that could not be duplicated by similar schemes elsewhere. Nevertheless, these di culties could inluence to a certain point public attitudes relecting the social acceptance of BRT. Finally, the critics of BRT often cite comfort issues when comparing bus systems with rail. As a matter of fact, many past studies have found that, other things being equal, most public transport users prefer rail to bus because of its greater comfort (Abelson 1995). Due to the fact that most BRT systems in developing countries use very high occupancy standards, as a result of inancial restrictions that would allow the provision of a level of service exceeding what customer fares can strictly inance for operation and vehicles, the standard of comfort can be neglected (Hidalgo and Carrigan 2010). However, Currie (2005) documents that there is actually evidence to support the fact that BRT has generally similar performance to light rail in the perceptions of passengers regarding comfort. Indeed, the average results of his study suggest that BRT may perform as well as rail with the other factors identiied, depending on the scale of the BRT system and the quality of its stations and facilities. Table 1 is a synopsis of the strengths and weaknesses and the opportunities and challenges that BRT represents today. It is a practical framework that looks into BRT from six diferent angles that refer to realistic concerns regarding BRT’s actual use: 1) economy, 2) technology, 3) lexibility, 4) implementation, 5) performance, and 6) impact. 2 he authors recognize that some of strengths and weaknesses presented in Table 1 are of a broader nature and, thus, could be in some degree applicable or could be generalized to other mass-transit modes.

Following a few pioneering implementations in the later 20th century, BRT has emerged as a leading mode of urban passenger transit in the irst decade of the 21st century (Deng and Nelson 2011). Many of these new implementations are taking place in cities throughout the developing world, attributed largely to the relative inexpensive cost, easier implementation, and greater lexibility as compared to rail systems, and their promise to foster economic revitalization (Levinson et al. 2003).

New BRT systems and BRT extensions are under development as well. he most important point of reference for BRT systems worldwide is South America, the birthplace of this mass transit mode. he South American schemes are widely appreciated as the most advanced and widely-used BRT systems in the world and provide a vision of how BRT can be used to radically change urban modal split in favor of public transportation. More speciically, BRT schemes have been implemented in 60 diferent locations in South America, hosting 62.4 percent of global BRT passenger trips (as of December 2014). Recently, several cities in Asia have adopted BRT operations. he potential for BRT implementation in Asia is still huge, but this has been recognized only recently by Asian policymakers. Actually, the newer cities joining the list of the urbanities with BRT corridors are concentrated to China, followed by Indonesia, with the Latin American region coming in third. China, fostering one of the fastest-growing economies in the world and experiencing an unprecedented urbanization and motorization that has greatly transformed the nation’s urban landscape over the last years, is the most fertile ground for new BRT schemes to prosper. Currently, 18 Chinese cities host at least one BRT corridor, but most of these schemes are of minor scale for the magnitude of the Chinese mega-cities. his trend is even clearer in India, where BRT operates in 8 diferent cities, serving only 390,000 passengers per day.

In Oceania, there are six cities hosting a BRT scheme; ive are in Australia. A seventh scheme in Melbourne (i.e., SmartBus) contains elements of BRT infrastructure but is no longer listed as such in the brtdata.org database. he introduction and usage of BRT in North America is limited compared to the potential opportunities that exist in the U.S. and Canada markets. Most schemes that are operating have small usage rates in relation to the dedicated BRT kilometers ofered. Europe, on the other hand, is a very diferent story when attempting to assess BRT’s operability, productivity, and success. In Europe, the bus sector has a long tradition of innovation and development in introducing bus lanes, bus-only roads, traic management measures to assist buses, and automatic dispatch and control systems—in some cases, as early as the 1970s (Hidalgo and Gutierrez 2013). Nevertheless, BRT has not been embraced with the same enthusiasm. One explanation is that during the 1990s, tramways were favored and received a lot of attention, while buses and bus systems were left behind. Nonetheless, the number of BRT systems in Europe is steadily increasing, especially in France and the UK. Researchers and practitioners in Europe prefer to use the term Buses of High Level of Service (BHLS) rather than BRT (Finn et al. 2011). his is the case because they want to differentiate the European applications, which are based on improving passenger experience rather than simply focusing their eforts on how to supply high-capacity mass transit. In the report from CERTU (2005), BHLS is deined as “a public road transportation concept for the structuring services of the network that meet a set of eiciency and performance criteria, coherently integrating stations, vehicles, circulation lanes, line identiications, and operating plans in an on-going manner.” However, the BRT vs. BHLS theme is far from simply being a quantity vs. quality aspect. he advanced bus schemes across Europe, with the exception of Istanbul’s Metrobüs, are not BRT systems that resemble Bogotá’s TransMilenio or Curitiba’s RIT but rather are BRTLite. BRT-Lite is a term that is more or less synonymous with BHLS, which explicitly refers to a system of buses with a high level of service that, despite its advanced characteristics, when compared with a conventional bus-line is not a fully developed BRT system, but rather a French/European BRT version of signiicantly smaller scale suiting European city needs. BHLS can have a considerable impact when implemented as part of the “co-modality” concept promoted by the EU—for example, working in cooperation between public transport leet operations and parking management systems to promote BRT corridors (Deng and Nelson 2011). A Brief BRT History Lesson BRT is an evolution of bus priority measures, such as designated busways and bus lanes (Hidalgo and Gutierrez 2013) and relects a vision that was inspired almost 80 years ago. he idea of using rubber-tired vehicles to provide rapid transit is well-documented in plans and studies that have been prepared since the 1930s, with growing emphasis on bus prioritization (Levinson et al. 2003). For example, in 1937, the so-called Chicago Plan called for converting three west-side rail transit lines to express bus operation on super highways A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 15 with on-street distribution in central areas (Levinson et al. 2003). he term BRT was initially used in 1966 in a study for the American Automobile Association by Wilbur Smith and Associates, but a proper full-scale implementation came almost two decades later. he irst real BRT system was implemented in Curitiba in 1963, although dedicated bus lanes were not operating until 1974 (Rabinovitch and Leitman 1996). Curitiba, with 1.85 million inhabitants occupying a total area of 435 km (about 4,200 inhabitants per km), is the seventh most populated city in Brazil and the largest in the southern region of the country. he city stands at the center of a metropolitan area that includes 26 municipalities with a total population of 3.17 million inhabitants. As early as the 1960s, Curitiba’s policymakers had the inspiration to direct the city’s growth by integrating urban transportation, land-use development, and environmental preservation using bus-based transit innovation as their main apparatus. In a December 2013 discussion with the authors, the Mayor of Curitiba, Jaime Lerner, the political champion who introduced this irst BRT application in the world, stated that “the inspiration behind the creation of a metro-nized, in terms of performance bus system,” was based on three parameters: 1) relecting the restrictions of the local economy that could not cater to the massive inancial needs for building and eventually sustaining a metro system; 2) understanding that the future of transportation was on the surface (and not underground)—he explicitly referred to “the need to have an interactive urban environment that integrates mobility, in a very visible way, with the overall sustainability focus of the city”; and 3) maximizing the potential of an already-existing bus system by transforming it in a cost-efective but yet unparalleled way that could it his vision of a city working, living, and moving as a whole like a living organism. As originally described by Lindau et al. (2010), the Curitiba bus system evolved from conventional buses in mixed traic to busways, which were later itted with loor-level boarding, prepayment, and articulated buses, creating the irst full BRT system in the world. Later, the city introduced high-capacity bi-articulated buses and electronic fare ticketing systems. In 2007, RIT (the name of the scheme) had 2.26 million trips per working day transported by a leet of 2,200 buses that produced 483,000 km per day. In 2009, the RIT was upgraded with the introduction of the Green Line, its sixth BRT corridor, which includes the operation of 100 percent bio-diesel articulated buses. As of 2010, some of Curitiba’s corridors had achieved performance to levels that are typical for metro systems (Lindau et al. 2010). he capacity of the Boqueirão Corridor, for example, serves up to 89,000 passengers per day, and its operating commercial speed for the express service is approximately 28 km/h. Today, RIT is responsible for 508,000 passenger trips per day over its 81 km (www.brtdata.org, December 2014). Curitiba’s operational framework was adapted to a signiicant degree for introducing BRT corridors in places such as Quito (1995), Bogotá (2000), Los Angeles (2000), Mexico City (2003), Jakarta (2004), Beijing (2005), Istanbul (2008), and Guangzhou (2010), to name a few. Nonetheless, suicient time passed for this public transit philosophy to disseminate to other locations. he vast majority of cities around the world that adopted BRT operations embraced this choice from 2000 onward, as illustrated in Figure 2. A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 16 FIGURE 2. BRT Implementation History Source: www.brtdata.org, December 2014 Presenting and Discussing Local BRT Applications he main focus of this section is to present updated information on speciic local BRT applications that could be representative of their geographical region, followed by appropriate discussions. hese discussions could be generalized into wider context for cities with similar characteristics and could serve as valuable lessons for building future BRT applications. here are many more examples that could have been discussed, but due to space restrictions, this was not an attainable choice. South America TransMilenio, Bogotá, Colombia Other than Curitiba, the inluence of Bogotá has been particularly important in setting the standards for what BRT is really about. he TransMilenio BRT system is the most powerful BRT reference for planners and practitioners worldwide (Gutierrez 2010). Bogotá is the capital and largest city of Colombia, with 7,760,500 inhabitants. It is among the 30 largest cities in the world and has 20 localities, or districts, that form an extensive network of neighborhoods. TransMilenio, widely known as the “Jewel of Bogotá,” has received many tributes, including the Stockholm Partnership Prize in 2002. It is the largest investment in public transportation in Colombia in the last decade, with signiicant impacts on travel times, transportation costs, the environment, accidents, and urban development of the nation’s capital (Hidalgo et al. 2013). It was built in three years, efectively from scratch, as the answer to the persistent demand for a metro system (Gilbert 2008). On an average working day in 2014, the system carried 2.21 million passengers in 113 km of lanes in 11 corridors (www.brtdata.org, December 2014). TransMilenio began operations in December 2000. Its key features as described by Gilbert (2008) include the following: • he system was built in stages, aiming to cover 80 percent of the urban transport needs of the city (Gómez 2004). • Each corridor is built along the city’s major roads, and the construction of the bus stations, garages, bridges and other infrastructure was inanced by public funds. A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 17 • TransMilenio operates using a public-private partnership mechanism. City administration is responsible for the construction and maintenance of the infrastructure (through the Urban Development Institute) and for the planning, management, and control of the service (through Transmilenio S.A., the private operator). he system operated originally on a commission of 3 percent of the fares collected, a percentage that has risen over time (Hidalgo et al. 2013). • here is no operating subsidy. • Red articulated buses operate along reserved corridors, with two exclusive lanes each way on most routes; a feeder system takes passengers to the main stations. • In 2011, 1,262 articulated buses and 10 bi-articulated buses were operating 114 stations around the city, in addition to 519 conventional 12m buses that operated within the 83 diferent feeder routes (Hidalgo et al. 2013). • Each articulated bus can carry 160 passengers, with 112 standing and the remainder sitting. • he red buses belong to 7 “modern,” private companies that have contracts with the city; the green feeder buses belong to another 11 companies. • Some buses stop at every station; others are express services. • Passengers board and alight the buses at special stations, many of which can be reached by pedestrian bridges to avoid accidents and to speed up loading. • Passengers purchase travel cards before boarding. A ixed fare is charged whatever the length of the journey. he use of the feeder bus system is free; passengers are charged only when they board on the articulated buses. he payment system also embraces the use of a smart card (Hidalgo et al. 2013). he fares are collected by Transmilenio S.A. • Transmilenio S.A. monitors and controls the system through a GPS system and communicates with the drivers through a wireless telecommunications system. • User information is achieved through a ixed signage and dynamic display panels (Hidalgo et al. 2013). • he buses have to be replaced on a regular basis, approximately every 10 years, although this can be extended to 15 years if the buses have not completed an agreed mileage. • he drivers are salaried employees of the bus companies. TransMilenio may be a minor miracle, but Bogotá is still in need of improving its transport system. Perhaps the main lesson that other cities planning to invest in busways should learn is that TransMilenio-type systems can work eiciently and should be encouraged, but unless parallel changes are made to the rest of the transport sector, real progress will be slowed and, in a worst-case scenario, vested interests may actually undermine the viability of a new BRT system (Gilbert 2008). A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 18 MIO, Santiago de Cali, Colombia Santiago de Cali (or Cali), the third largest city in Colombia, with a population nearly 2.5 million residents, is among the most recent South American cities to adopt a BRT system and is in the process of replacing its traditional bus public transit system with an integrated mass transit system. his city-wide transportation project is central to a larger urban revitalization plan intended to encourage economic growth and to alter the image of both the city and the country to residents and outsiders. What deines this scheme is the intention of planners to create a system that prioritizes equity over other potential goals. As Delmelle and Casa (2012) report, the policymakers’ ambitions focus on developing a scheme that promotes equitable access to all residents and access to a large number of urban opportunities. his is a scheme that on a daily basis accommodates 530,000 passenger trips in its 6 corridors that extend to 39 km (www.brtdata.org, December 2014). Lessons to be Learned by South American Applications Since BRT has a long tradition in South America, a discussion about South American scheme variety and success (or failure) as a whole is a meaningful process. his discussion, nonetheless, could be generalized into a wider context since these indings could be applicable to other systems that have not yet achieved the levels of maturity of the South American schemes. After Curitiba opened the irst BRT system, other cities in Brazil introduced systems with some of the same characteristics but with much lower speeds, capacities, and customer comforts. hese light BRT systems—São Paulo’s passa rápido corridors, for example— brought some real beneits to passengers but were far less appreciated by the general public. As a result, Brazil lags behind Colombia in terms of leading BRT development (Weinstock et al. 2011). BRT systems in South America (and in Asia, in this case, since there are similarities) feature a diversity of scope and level of integration. here are single-corridor projects that do not integrate with feeder services and other transport modes (e.g., Mexico City, Beijing), projects with sequential implementation of non-integrated corridors (Quito, Jakarta), schemes that gradually implement physically-integrated corridors (Bogotá, Guayaquil), and others that deploy extended route re-organizations (São Paulo, Santiago, León) (see Carrigan et al. 2011). A strong political champion has proven to be an asset in the development and implementation of BRT (Lerner 2013). he fares for South American BRT projects with competitive bidding for bus operating concessions (e.g., Bogotá’s TransMilenio, Pereira’s Megabus and TranSantiago) often have been determined through the bidding process itself. Initial user fares were calculated based on prospective operator bids, and the contracts then issued for operating have included adjustment formulas for future rises in labor and fuel costs over time. In other systems, political authorities deined fares that did not relect the actual costs of the system or the required levels of subsidy. his approach can have adverse efects. For instance, Quito’s system was unable to generate enough funds to pay the operators of the Ecovía buses, and the BRT systems of Mexico City (and, similarly, Jakarta and Beijing) were inancially challenged until fare increases were approved. Setting fares related to knowledge of the costs and an understanding of subsidy requirements are necessary to ensure inancial A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 19 sustainability for operators and funding authorities as well as continued political buy-in (Carrigan et al. 2011). It is also common for cities to incorporate existing operators into the new BRT system to minimize political and contractual risks referring to service operation. Cities in South America (and now in Asia and Africa as well) have encouraged small transport businesses and operators to organize themselves into formal companies through restricted bidding for operation contracts or through direct negotiations (Carrigan et al. 2011). his encourages local communities and businesses to engage more actively with the scheme of their city by sharing some responsibility for its functional operation. Even more important, however, this helps to secure working posts that could be in doubt if a large contractor was in command—something that inluences local economic development positively. his is an operational issue that perhaps deserves a study on its own, but since it is an important success ingredient for BRT, it is reported as such for the sake of a more holistic approach. Europe Metrobüs, Istanbul, Turkey A scheme that is considered among the most successful is Turkey’s Metrobüs, the only intercontinental BRT system in the world. his is a success story not related with South American schemes, although it was inspired by them. he implementation of Metrobüs started in 2007. It was initially built on the European side of Istanbul through a high-demand arterial and received criticism for being preferred over rail alternatives. he section that was built in 2009 runs over one of the two Istanbul Strait (Bosporus Strait) bridges connecting Asia and Europe, by which Metrobüs has uniquely acquired the distinction of crossing a major water barrier and connecting two continents. Istanbul Strait is a major transportation bottleneck and source of congestion, and Metrobüs is the only transit system for crossings. Shortly after the opening of the bridge section, the whole system recorded a directional capacity of 24,000 passengers per hour and patronage of 620,000 daily trips (Alpkokin and Ergun 2012). he one-corridor BRT scheme after its fourth phase in 2012 extends to 51.3 km (Yazici et al. 2013). Currently, Metrobüs carries 750,000 passengers per day serving Istanbul, one of the largest cities in the world, with a population of more than 13 million inhabitants (www.brtdata.org, December 2014), which, similar to other megacities in terms of size and complexity, has a metropolitan area even larger. Metrobüs uses the application of a median busway with center island stations that was built within the median of the freeway D100 by removing a travel lane in each direction. Bus operation is counter-low to reduce costs and implementation times and uses conventional buses with right-hand doors. he entire Metrobüs system has a dedicated right-of-way in Istanbul, with the exception of mixed traic operations on the Bosporus Bridge. Alpkokin and Ergun (2012) conclude their assessment of Metrobüs by reporting that “all the information of improved ridership and capacity proves that Istanbul Metrobüs achieves one of the highest patronage levels amongst similar BRT systems, which provides evidence to support the efective operation of BRT systems.” A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 20 Stombussar, Gothenburg, Sweden Gothenburg has approximately 540,000 inhabitants and is divided by the Gothia River, with the south and the north parts crossed by two bridges and one tunnel. Public transport accounts for 29 percent of all trips; 48 percent are by private car, 14 percent by motorcycles and non-motorized vehicles such as bicycles, and 9 percent by walking. he public transport system in Gothenburg consists of trams, BRT-Lite routes, and other bus services including express buses. here is also a ferry service across the river and to/ from the archipelago. Most public transport journeys are made by trams (60%), but the BRT system is gaining in popularity and carries around 15 percent of the passengers of all public transport trips (Traikverket 2014), that equal approximately 25,000 passenger trips per day (www.brtdata.org, December 2014). he BRT system, or, more precisely, the trunk bus system, was irst introduced in 2003. Currently, eight lines are considered trunk bus lines or “stombusslinjer.” Line 16 initially had a 10-minute frequency during peak hours; the current frequency is 5 minutes during most of the day and 2.5 minutes in the most demanding directions during peak hours. he other seven BRT routes run with at least 10-minute frequencies during daytime, in some cases reinforcing traic during peak hours. To minimize the times at each bus stop, travelers are allowed to get on and of through all doors, a so-called “open visa” regime. his corresponds to the principles that apply to trams in Gothenburg, but is not allowed in other, ordinary bus lines. Buses are given priority at all traic lights en route. he position of all bus stops was reviewed, leading to a minimum number of bus stops in relation to traveler needs, and special bus lanes and bus streets were created. When planning the routes, eforts were made to avoid sharp curves and lateral movements; this has been achieved by providing a straight line into and out of the bus stops and bus lanes, which run straight through roundabouts, etc. All these actions lead to a higher average speed. Most bus stops in the BRT system are equipped with real-time information displays, presenting information on next departure as well as disturbances and delays. On all buses, internal displays inform the passenger about the next two stops. A special road map presents the trunk bus lines together with the tram system to further stress the relationship between the two. he ticketing system is an electronic smart card system. Tickets cannot be purchased on board, but individual tickets can be purchased via SMS just before the trip and are valid for 90 minutes, or cards can be purchased from local shops. Approximately 65 percent of passengers use monthly passes. he entire bus leet consists of low-loor buses with wheelchair ramps. In addition, all stops have a raised platform to improve accessibility for mobility-challenged passengers. he buses have a unique and uniform design to make them easily detectable in city traic. For interior design, care was taken in the choice of colors, materials, and lighting to make the travel experience more pleasant for travelers and to assist passengers with disabilities. It should be noted that this BRT scheme is substantially scaled down compared to the world’s leading BRT schemes; it is not oriented towards dealing with higher capacities but, rather, emphasizes the provision of high-quality services. Conclusions from previous Swedish research on BRT indicate that there is no place for full-scale BRT schemes in A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 21 Sweden, even though Swedish towns and cities could beneit from the image, lexibility, speed, and quality that BRT symbolizes (Stojanovski 2013). he urban form, the road hierarchies, and the dispersed and fragmented urban structure of Swedish towns and cities and low densities were identiied as main obstacles (Kottenhof 2010). Asia TransJakarta, Jakarta, Indonesia Jakarta is the capital and largest city of Indonesia and is located on the northwest coast of the island of Java. It is the country's economic, cultural, and political center and, with a population of around 10 million, is the 13th most populated city in the world. TransJakarta BRT System launched its irst corridor on January 2004 on a trial basis, beginning revenue operation on February 2004 (Ernst 2005). his was the irst fully operational BRT system in Asia. During its irst year, it served 15.9 million passengers. Beginning with just 12.9 kilometers, TransJakarta is now 206 km (www.brtdata.org, December 2014), larger than the BRT systems in Curitiba and Bogotá (Yunita 2008). his is a scheme that has all the key elements of a BRT system. It is founded on a designated busway that is physically separated from mixed traic, except for very few cases where segregation was not feasible. TransJakarta ofers facilities such as air-conditioning and pre-paid boarding that distinguish it from other buses. Currently, 12 corridors operate, serving 370,000 passenger trips per day (www.brtdata.org, December 2014). In its irst year of operation, TransJakarta was responsible for a signiicant modal shift, with 14 percent of private car users using BRT (Susilo et al. 2007), a measurement that relects the period occurring four months after the launching date of the irst eight corridors. TransJakarta’s ridership is rather low, with systems that have less than one-quarter of TransJakarta’s infrastructure carrying more passengers per day. For example, Belo Horizonte’s BRT system is approximately 5 times smaller than TransJakarta, with 5 fewer corridors and carrying 682,000 passengers per day on its articulated buses. One efort to improve the customer experience and attract ridership included the installation of water fountains in several stations, intended for passengers observing Ramadan, the Islamic month of fasting, to be able to break their fast in the station during their commute home. he cost of the water puriiers was about $2,136 each (Yunita 2008). he main problems of the scheme are long queuing times and insuicient bus frequency. he initial corridors were constructed for buses with only one door, constraining the number of people who could get of or on the bus at one time. he new corridors will include a ix to this problem. Information provision is not eicient since it is provided only in stations by ticketing oicers, security oicers, and a display board. Cleanliness and maintenance are important concerns as well. BRT1, Beijing, China Beijing is the capital of China and one of the most populous cities in the world, with more than 20 million inhabitants. he metropolis is governed as a direct-controlled municipality under the national government, with 14 urban and suburban districts and 2 rural counties. Beijing Southern Axis BRT Line 1 (BRT1) is the irst BRT system implemented in China and the irst large-capacity rapid bus line based on the needs of developing public A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 22 transportation, which was designed using foreign advanced ideas and technology as reference (Lin and Wu 2007). BRT1 started commercial operations in December 2004 with a pilot line of only 5.5 km in length. In December 2005, BRT1 began full operations and was extended to 15.8 km. It should be noted that from proposal to trial operation, the time span of implementing BRT1 was relatively short. Most lanes are physically segregated in the median of the road, except for 2 km from Qian’men to Tian’an’men. Six of the 17 stations of the corridor are transfer stations (Deng and Nelson 2013). Accessibility to the city center has been signiicantly improved for residents along the BRT corridor. The BRT system investment at Beijing Southern Axis Corridor included significant expenses for the creation of the necessary road-reconstruction project, stations, and intelligent transportation systems (ITS). he investment in the road reconstruction project was about 321.31 million yuan, and the investment for the stations and ITS (including operation for stations, parking lots, vehicles, etc.) was approximately 288.19 million yuan, for a total cost of 609.5 million yuan; construction cost per kilometer was about 38.1 million yuan (Lin and Wu 2007), a cost in American dollars (in 2014 values) of approximately $6.2 million. In Beijing, the local authority has faced increasing di culties in paying of debts for subsidizing its metro and light rail operations and for expanding the rail network to increase coverage. In a pre-implementation cost-beneit study on three transport improvement alternatives (busway, street-level light rail, and elevated rail) in a congested corridor in Beijing, it was found that only the busway showed a positive net present value (Deng and Nelson 2013). his rationale led Beijing policymakers to implement, on a relatively small scale (for the city standards), BRT to save costs and eventually provide high-quality services within a short implementation time. Currently, Beijing has 4 corridors covering 74 km of routes and hosts on a daily basis 305,000 passenger trips (www.brtdata.org, December 2014). he lines use vehicles with a passenger capacity of 180 persons (Lin and Wu 2007), and all are low-loor buses and cost about US$250,000 each, including features such as automatic stop announcements, three double left-side doors, and air conditioning (FTA, 2006). he buses are mounted with GPS terminal equipment and meet universal emission standards. he speed of the buses reaches 26 km/h, and (according to Lin and Wu 2007) the overall travel speed of general traic after BRT implementation of the Southern Axis Line has increased by 2.26 km/h. A user survey conducted by Deng and Nelson (2012) suggested that passengers were generally content with the BRT service provided in the Beijing Southern Axis BRT Line 1, with 85.5 percent rating overall satisfaction as “very satisied” or “satisied.” High speed and convenience were the main factors encouraging passengers to use BRT. It was also found that passengers who had a car alternative were more likely to give lower satisfaction ratings regarding the reliability, comfort, cleanliness, and overall satisfaction of the BRT service. Overall, the implementation of BRT in Beijing is regarded as a considerable success because of its prominent lexibility, transit speed (close to that of the Beijing Metro), and user satisfaction (Deng and Nelson 2012, 2013; Lin and Wu 2007). However, some problems do exist. In Beijing, an impressive feature of BRT stations is a pedestrian overpass or A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 23 underpass, which provides safe pedestrian access; adding lifts and elevators would make these stations even more accessible to mobility-challenged groups. Fares are below the operation cost level, which has generated considerable inancial di culties for the operators. Currently, Beijing’s BRT is heavily subsidized by the local government, but because it has high passenger volume levels and low labor costs, it could be proitable, provided that the system operation structure is redesigned accordingly. he local authority needs to re-examine the efect of subsidies on operational eiciency and conduct a full review of its fare policy and structure to improve the operational sustainability of BRT. Adding more express buses at large stations and intersection services during peak-hours while reinforcing the leet with super-capacity vehicles could, according to Lin and Wu (2007), bring immediate improvements to the system. Unrealized Potential for BRT Investments in Asia In many developing Asian cities, the growth of transportation needs is very rapid and uncontrolled, causing various impacts on the environment and human welfare (Satiennam et al. 2006). he reality is that until recently, heavy investments have been made exclusively in building metro and light rail systems as a means to meet massive travel demand. Pucher et al. (2007) suggest that although metro and light rail projects have gained extensive political support in Asia, in some cases, this is mainly because “rail symbolizes modern, advanced technology and ofers politicians tangible, highly visible achievements to impress their constituencies and the rest of the world.” hus, the prioritization of rail-based solutions was primarily founded for image and national pride purposes and not on the provision of a mechanism adequate to deal with urgent traic congestion problems. BRT has recently emerged as an attractive urban transit alternative in many Asian cities due to its inancial sustainable, ecologically-friendly character and its lexible implementation. However, it seems to be di cult to introduce BRT, at least on a scale that relects the size and traic challenges of Asian mega-cities. Ten countries and 38 cities in Asia have a BRT scheme to date, but none is comparable in size or performance to the schemes of South America. Some of them also lack innovation and are limited to unsuccessfully adapting BRT operations that do not it the local needs of the city hosting them. For instance, after Indonesia opened TransJakarta, a system with signiicant problems of its own, other cities across Indonesia began opening copycat systems, the best of which brought about only marginal improvements and the worst of which made conditions worse. Chinese and Indian cities, after gaining some limited familiarity with Bogotá’s TransMilenio, also made a number of sub-optimal bus system improvements that were branded as BRT but which could not be judged as cost-efective (Weinstock et al. 2011). Furthermore, the lack of upfront integration of road design, public transportation planning, land-use planning, and early-stage public consultation has created challenges to providing high-quality public transport services on many new urban corridors (Jiang et al. 2012). Deng and Nelson (2010) add that, despite the fact that BRT systems are successfully in operation across the world (and in Asia in particular), the image of BRT is not yet well understood by most decisionmakers. his means that it is di cult for them to transform a concept that is often misunderstood into new local applications that could genuinely A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 24 improve road traic conditions. Yet, with more than 100 cities of more than 1 million in population only in China, the urban transportation market in Asia is very large (FTA 2006)—too large to address by simply supporting car-orientated operations and conventional public transport services. North America HealthLine, Cleveland, USA he most successful example of BRT in the U.S. (with a BRT Standard score of 63/100 compared to Eugene’s EmX 61, Los Angeles’ MetroRapid 61, Pittsburgh’s Martin Luther King, Jr. East Busway 57, and Las Vegas’ MAX 50) is the 11.4 km Euclid Corridor Transportation Project, also known as HealthLine. his is a scheme that is not really comparable to the productivity, eiciency, or size of a scheme such as Bogotá’s, whose BRT Standard score is 93. Healthline is a one-corridor scheme serving 15,000 passenger trips per day (www. brtdata.org, December 2014). his project was created in response to the need for providing an eicient public transit service connecting the city’s main employment centers. he Greater Cleveland Regional Transit Authority (RTA), the Northeast Ohio Areawide Coordinating Agency (NOACA), and the City of Cleveland had studied transit options in Cleveland for four decades, culminating with the consensus in 1995 that BRT would be the most cost-efective option to provide high-capacity transit service for the city (Weinstock et al. 2011). he project details for the Euclid Corridor Transportation Project were inalized in 1999 following a series of 12 public consultation meetings. Before the system opened, average bus speeds in the corridor were only 15 km/h. Line 6 on the Euclid Avenue corridor was one of the most heavily-used routes in the city, accounting for 10 percent of the total passenger trips. Euclid Avenue also had lines 7 and 9 operating on part of the corridor. he operational plan for the HealthLine converted line 6 into an upgraded service with new articulated BRT buses that operate mostly within a newly-constructed segregated right-of-way. he original low-loor 7 and 9 buses also are able to use the BRT infrastructure at station stops with right-side boarding. A total of 32 buses also use the BRT corridor in some places. Together, these 4 lines average an interval of 2.1 minutes between buses during the peak, and speeds in the corridor average a respectable 20.11 km/h (Curitiba BRT averages about 21.06 km/h and Bogotá averages 26.2 km/h). More than 13 additional routes that overlapped the corridor for short distances or were in the impact area of the corridor have been rerouted. Some of the speed increase resulted from the elimination of stops, which some residents complained about along with the inconvenience resulting from the changes in routes, but that was the only negative side-efect. Daily ridership increased by 60 percent after 2 years of operation. he project’s total budget was approximately $200 million, but only $50 million was allocated for buses and stations; the remainder was directed towards other corridor improvements such as roadways, utilities, new sidewalks, and street furniture. he cost of the busway itself, therefore, was only about $7 million per mile, including rolling stock. he investment has resulted in nearly $4.3 billion in economic development for the area (Zingale and Riemann, 2013) in A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 25 real estate investments along Euclid Avenue, one of the city’s most historically-signiicant corridors. A very intriguing factor of the scheme (that perhaps could be a point of reference for more BRT schemes) relates to the fact that Greater Cleveland sold the naming rights of the line to help fund the system. he Cleveland Clinic and University Hospital jointly purchased the naming rights, resulting in the HealthLine name. his partnership will provide the system with $6.75 million in additional funding, dedicated to maintenance, over the next 25 years. North America is Still “Testing” BRT he development of BRT systems is relatively recent in the United States; however, several systems are operating, and many more are being planned (Perk et al. 2010). Until recently, the U.S. and Canada (partly because BRT is not ideal for the population density of the typical Canadian urban structure) have not yet relied heavily on BRT. Having witnessed the success of BRT schemes such as those in Curitiba and Bogotá, a number of American cities began developing BRT-type systems. Some of these systems have brought signiicant beneits and won public approval. However, even the best U.S. systems lack some key characteristics of the world’s best BRT systems, and none have fully captured the imagination of American motorists and voters (Weinstock et al. 2011). American cities started investing in BRT as a viable alternative after it was solidiied as a worldwide phenomenon. However, the concept of employing rubber-tired vehicle leets to provide rapid transit and the term BRT itself could be of American origin (Levinson et al. 2003). Since there is still no consensus on what constitutes a full-scale BRT system (Wirasinghe et al. 2013), the not particularly infrastructure-heavy American BRT systems have been labeled by some (e.g., Weinstock et al. 2011) as “modest bus system enhancements corrupting the BRT brand.” Nonetheless, each BRT system is a unique solution itting the needs of the city in which it is implemented and should be addressed as such. he role BRT is asked to play in the U.S. because of federal and other cultural and institutional diferences is that of a complement and not of a sole solution. Similar to Europe, there is a focus on quality rather than quantity. Perhaps, to allow for BRT to grow to its full potential in North America, more comprehensive understanding is needed of the relationship between land use and BRT, particularly in comparison with other ixed-guideway modes (Perk et al. 2010). Understanding the mode’s impacts on property values, in particular, could be another key for embracing the measure if the impact is somewhat comparable to that of rail-based services (Perk et al. 2013). he emergence of BRT, in this sense, should not be seen as a problem despite all its current limitations, but rather as “a unique opportunity to change negative perceptions regarding public transit in North America,” as Hess and Bitterman (2008) argue. Currently, 18 cities in the U.S. host 32 corridors and 548 km of dedicated BRT road infrastructure, but only 365,000 passenger trips per day (www.brtdata.org, December 2014) take place, which, in comparison, is less than half of those completed daily in Instabul’s Metrobüs. Canada, in respect, has 8 cities with BRT schemes, hosting 530,000 passenger trips in 18 corridors spanning 250 km (www.brtdata.org, December 2014). A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 26 Africa Lagos BRT-Lite, Lagos, Nigeria Among the three African BRT applications, the most recognizable is perhaps the one in Lagos, Nigeria. Lagos is one of the fastest growing cities in Africa. Data for “building up” urban area population is a particular concern in Nigeria; the 2006 census results were highly disputed. For example, the federal census indicated a population for the state of Lagos of 9.1 million; a parallel census conducted by the state found the population to be 17.5 million (Demographia 2014). he 22 km Lagos route is Africa’s irst BRT scheme and became operational in March 2008. It is termed “BRT-Lite,” meaning that it is not a scheme of the highest speciication such as TransMilenio in Bogotá. It is a new form of BRT, focused upon delivering a system to meet key local user needs, with the aim of improving quality of life, economic eiciency, and safety within a clearly-deined budget. he implementation of a 15-month conception-to-operation program, together with its delivery at a cost of $1.7 million per km, makes its development unique internationally (Brader 2009). he Lagos BRT-Lite carries almost 200,000 people per day (www.brtdata.org, December 2014). Its single route is 65 percent physically-segregated and 20 percent separated by road markings. However, its success is not purely based on its infrastructure but on a holistic approach that involved the reorganization of the city’s bus industry, inancing new bus purchases, and creating a new institutional structure and regulatory framework to support it, together with the training of personnel to drive, maintain, enforce, and manage BRT (Brader 2009). An early evaluation of the scheme showed that users were saving journey time, had fewer interchanges en route, were traveling cheaper, and felt safer (Brader 2009). Adebambo (2009) also suggests that BRT has a signiicant impact on passenger satisfaction in Lagos metropolis; it has helped to improve the quality of life of not only its users but also those that travel along the corridor using other modes, as well as those who choose to locate their businesses there. Businesses within the corridor saw the scheme as a positive addition, improving accessibility and aiding their access to staf and the ability of their staf to travel for work-related duties (Brader 2009). Negative aspects relate primarily to the need for more buses and more routes. Problems exist, and improvements relating to the system’s eiciency are necessary. According to Adebambo (2009), there is a need, for instance, to ensure greater coordination with local planning and operating agencies for the purpose of identifying BRT potential, and a need to conduct research, develop operational techniques, and promote the use of ITS technology to enable safe and eicient deployment of BRT. BRT implementation also may require policy and institutional reforms, such as changes in transportation planning and roadway management practices (to give buses priority in traic), vehicle purchasing, transit regulations and contacting (to maintain a high quality of service), and urban design (to increase development near BRT routes). he scheme overall seems to have a beneicial efect upon the quality of life of the commuting population of Lagos. A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 27 Oceania Brisbane Busway, Brisbane, Australia Australia and New Zealand, due to their small populations compared to their vast landmasses, are more likely than most countries to have strict limits on public spending, including transport infrastructure and operations. his means that bus-based systems can be the only viable solutions for some Oceanic cities. Australian BRT systems have been noted as being particularly diverse in design (Currie 2006), with systems now operating in Sydney, Brisbane, Adelaide, and, to a lesser extent, Melbourne (Currie and Delbosc 2011). he system in New Zealand is the one-corridor Northern Busway in Auckland, operating 22 km and generating 22,900 passenger trips per day (www.brtdata.org, December 2014). he Adelaide O-Bahn is the oldest BRT system in Australia and one of the irst BRT systems worldwide; it opened in 1989 (Currie 2006). he Brisbane Busway is the largest BRT system in Oceania, with 3 corridors running on 28 km and serving 356,800 passenger trips per day (www.brtdata.org, December 2014), which is about the same passenger volume as the huge TransJakarta scheme that was built to cater the needs of a city ive times the size of Brisbane. he system is recognized as one of the most successful BRT systems in a developed economy, and, by Australian standards, is regarded as one of the most successful mass transit systems, delivering fast, comfortable, and cost-efective urban mobility through the provision of segregated rightof-way infrastructure, rapid and frequent operations, and excellence in marketing and customer service (Gollota and Hensher 2008). For the high-level strategic criteria of value for money and increased accessibility, connectivity, and visibility, the Brisbane BRT excels, according to Gollota and Hensher (2008). Conclusions BRT systems are celebrated worldwide as an increasingly popular public transport development option (Currie and Delbosc 2011). his is due to their promise for delivering relatively low-cost, rapidly-implemented, lexible, and high service quality solutions to developing cities’ transportation needs (Wright and Hook 2007). here is an increasing number of highly-congested urban environments in need of a public transport mode with a vast potential for eco-innovation that could be assessing the merits of BRT. As pointed out herein, if BRT is well-designed and supported adequately by local policymakers, it can be a high-capacity public mode that could capture road-user loyalty. Furthermore, by reviewing BRT examples from all over the world, and especially concentrating on cases that have been revolutionary, this work provides an identiication of prototype mechanisms for reconstructing success. Combining the quality standards of a tram or metro system with the lexibility and ease of a conventional bus system at a signiicantly lower expense than that related to ixed rail operations could challenge the merits of car-oriented mobility in any eco-friendly society. International practice supported by current BRT user satisfaction levels (as reported, for example, for Beijing by Deng and Nelson 2012) suggest that BRT schemes could be highly-acceptable strategies for relieving traic problems and promoting sustainable living conditions. A Worldwide State-of-the-Art Analysis for Bus Rapid Transit: Looking for the Success Formula Journal of Public Transportation, Vol. 18, No. 1, 2015 28 BRT is a very demanding public transit medium that could transform the whole transport system within a city with two distinctive approaches—by re-allocating road space and by reforming the priorities of the city’s urban development policy. In addition to BRT’s dedicated road space requirements that call for the introduction of bus lanes on existing streets and bus streets completely separated from traic, BRT is based on a wide variety of other rights-of-way, including bus priority in signalized intersections. hese could radically afect the current balance of traic prioritization, minimizing the dominance of automobiles in streets. hus, introducing a full-scale local BRT scheme could rearrange the entire dynamics of a city’s mobility and, ultimately, force dramatic changes in modal share. Nonetheless, if the system fails to be attractive to the commuting audience, it could end up as an expensive iasco. In such a case, the scheme could, instead of promoting alternative and greener mass transportation, worsen the inner-city road conditions in terms of traic congestion by depriving road space from other more successful transport modes. herefore, strong political consensus, branding, image-making, marketing promotion, and the provision of user education are of invaluable importance for 1) easing the transition from conventional bus services to BRT and 2) solidifying BRT as a tangible long-term solution that could provide vital societal services for all road users and eventually become iconic for the very identity of the city hosting it.
