Since the 1970s great progress has been made to develop transit systems which provide service considerably better than buses can offer in mixed traffic, but which require significantly lower investment than metro systems with exclusive ways. This “semirapid transit” category of modes, using mostly partially separated ways, has been introduced extensively in medium-sized cities, as well as suppl...

Smart cities are not merely the infusion of technology into a city’s infrastructure, but also require citizens interacting with their urban environment in a smart and informed manner. Transportation is key aspect of smart cities. In this paper, we present a smart route planning open-source system; SMART-GH utilizes open data and participatory sensing, where citizens actively participate in coll...

This paper examines the agglomeration benefits of a transportation improvement in a city by modeling the microstructure of urban agglomeration based on monopolistic competition of differentiated intermediate products. Properly extended to include variety distortion in addition to price distortion, Harberger’s measure of excess burden yields the agglomeration benefits. The agglomeration benefits...

While there is no definitive agenda for making cities smarter in terms of mobility, intuition says that information is key. However, contrarily to a more technical view, information should not only be consumed by the users, but also produced by them. This is already happening (smart-phones, social networks) but is far from being exploited by technical systems related to transportation. In this ...

walking being the oldest form of urban transport, and until the advent of major transformationsin transport technology in the nineteenth century, most cities were structured in ways that supported walkability.today, there is a change in transportation which emphasizes, the traditional pedestrian paths which are increasinglybecoming non-regulated spaces when compared to the urban spaces for auto...

This article reviews quantitative and qualitative trends in urban transportation and environment, focusing on developing countries. Reviewing recent efforts to look at transportation, the article adopts a definition of “sustainable transportation” that includes economic and environmental sustainability as well as equity as key criteria. It is argued that governance sustainability is also import...

One of the most critical issues in modern cities is transportation management. Issues that are encountered in this regard, such as traffic congestion, high accidents rates and air pollution etc., have pushed the use of Intelligent Transportation System (ITS) technologies in order to facilitate the traffic management. Seen in this perspective, this paper brings forward a road traffic management ...

Transportation and its environmental impacts are a major component of urban environmental management. At the same time, transportation and mobility are an important part or urban economics and the quality of life. To analyse urban transportation and its environmental impacts, a comprehensive, interdisciplinary approach is needed. No single model can cover the range of spatial and temporal scale...

This report evaluates rail transit benefits based on a comprehensive analysis of urban transportation system performance in major U.S. cities. It discusses best practices for evaluating transit benefits. It finds that cities with larger, well-established rail systems have significantly higher per capita transit ridership, lower average per capita vehicle ownership and mileage, less traffic cong...
