Smartcard automated fare collection systems (SCAFC) for transit have been considered primarily for their administrative function of controlling access to the service and for revenue management. However, it is likely that data from these systems also can be used to describe both transport supply and demand. This article illustrates the use of smartcard data to estimate various transit performanc...

Optimal Design of Demand-Responsive Feeder Transit Services. (August 2009) Xiugang Li, B.E., Southeast University; M.E., Southeast University; D.E., Southeast University Co-Chairs of Advisory Committee: Dr. Luca Quadrifoglio Dr. Yunlong Zhang The general public considers Fixed-Route Transit (FRT) to be inconvenient while Demand-Responsive Transit (DRT) provides much of the desired flexibility w...

Increased provision of transit service and policy incentives that favor transit use can support a physically active lifestyle. We used the smartraq travel survey in metropolitan Atlanta, Georgia (in 2001-2002) to assess whether transit and car trips were associated with meeting the recommended levels of physical activity by using walking as a means of transportation. Additionally, we assessed a...

Current route planning algorithms for public transport networks are mostly based on timetable information only, i.e., they compute shortest routes under the assumption that all transit vehicles (e.g., buses, subway trains) will incur in no delays throughout their trips. Unfortunately, unavoidable and unexpected delays often prevent transit vehicles to respect their originally planned schedule. ...

Public transit ridership offers valuable opportunities for modest amounts of daily physical activity (PA). Transit is a more feasible option for most Canadian commuters who live too far from work to walk or cycle, yet public transit usage in midsized Canadian cities has historically remained low due to inefficient transit service. The objectives of this longitudinal study were threefold: to ass...

In many public transport oriented cities in the world, especially Asian cities, the public transport system has been developed extensively, to the extent that it has become increasingly difficult to navigate. Although inter-modal transfers are common and often necessary, a complete set of the routes across transport modes is generally not presented in a form that is accessible to travelers, as ...

w bile the United States has been investing in costly park-and-ride systems that have made transit increasingly dependent on the automobile, European and Japanese communities have been strengthening the potential for people to walk and bicycle to and from transit, boosting ridership at a far lower cost. In Japan and much of Europe, the fastest-growing and often predominant access mode to suburb...

Many scholars claim that public transit’s long-term ridership decline can be attributed to the decentralization of U.S. metropolitan areas and the decline of the central business district (CBD) as their primary economic engine. However, recent research has begun to challenge this view and has prompted this reexamination. Using multivariate analysis, we examine the relationship between the stren...
