Proceedings of the 10th International Conference of Chinese Transportation Professionals, held in Beijing, China, August 4-8, 2010. Sponsored by North American Chinese Overseas Transportation Association (NACOTA); Beijing University of Technology; Transportation and Development Institute of ASCE; Transportation Research Board Committee on Transportation in Developing Countries; National Natural Science foundation of China. This collection of 444 papers focuses on ways meet the needs of urban transportation systems in a capacity that is environmentally sound, socially equitable, and economically viable. In the last two decades, many large cities in China have experienced rapid urban sprawl, which has been resulted in extensive expansion and motorization of the cities. The threat of increasingly unsustainable urban transportation systems has become a focus of attention as the awareness of the unhealthy interaction between a surging demand for transportation services and the environmental impact of such increases. Topics include: comprehensive transportation planning; traffic safety theory and technology; transportation management; operation technology and systems; and public transportation technology and systems.
