Bus Rapid Transit (BRT) systems are undergoing rapid development in many countries due to the unique characteristics of this form of mass transit. In China, BRT schemes are being adopted as a key strategy for relieving traffic problems. As a case-study, this paper examines the performance and impacts of BRT in Beijing, the first full-featured BRT system in China. It considers in turn the role of ITS technology in influencing the operational efficiency, technical performance and cost issues associated with BRT. Particular attention is given to the consequent impacts of BRT on travel behaviour change, traffic environment and property development. While some challenges remain, the early performance of BRT suggests that it is one of the key measures for promoting sustainable mobility. 相似文献

Workshop 2 focused on the role of BRT as part of enhanced public transport service provision. Discussion topics included case studies around the world; improved performance and operations; and better contracts, institutional settings and enhanced policies. BRT was identified as a vital component of modern public transport systems due to its ability to provide high performance and rapid implementation at a lower cost than comparable rail transit. The participants concluded that on top of improving trunk transit corridors, it is important to look to the first and last kilometers and the connections among transport modes. In addition, it is important to consider all dimensions, not just the technical issues. The workshop identified the desirable ingredients for BRT success, created a table of bus based options for different applications and a list of research topics. 相似文献

Over the past two decades, Bus Rapid Transit (BRT) has become an established transportation technology, which delivers high quality, high capacity transit at much lower cost than rail-based modes. Although initially associated with South America, it is now global with a wide array of implementations in Asia, Africa, North America, Australia, and Europe. 相似文献

In the 1970s, Brazil was leading the implementation of high-flow bus priority schemes, but now cities are less capable of financing public infrastructures. This paper explores the private sector participation in the provision of transit infrastructure based on Public-Private Partnerships (PPP) for Bus Rapid Transit (BRT). The Porto Alegre BRT contemplates interchange terminals planned to accommodate retail and service activities. It is expected that these areas shall generate enough revenues to remunerate private investors, under a PPP scheme, for the construction of terminals and part of the infrastructure required to upgrade some sections of the existing busways to BRT standards. 相似文献
