Proceedings of the First International Conference on Transportation Information and Safety, held in Wuhan, China, June 30-July 2, 2011. Sponsored and organized by Wuhan University of Technology; Transportation & Development Institute of the American Society of Civil Engineers; China Communications and Transportation Association; National Natural Science Foundation of China; and Canadian Society for CivilEngineering. This collection contains more than 350 reviewed papers examining the problems and opportunities addressed by a multimodal approach for the sustained development of the transportation system in China. Modern information technologies and innovations in transportation safety management are key to improving the system efficiency and enhancing traffic safety. Multimodal and system-wide approaches are needed to develop solutions that are technically effective, socially equitable, environmentally sound, and economically viable. These papers promote sustainable transportation system development in the context of information systems and safety for four transportation areas: highways, air, rail, and water. Researchers, practitioners, and policymakers around the world will find this collection to be a great source of information on current practices in China.Abstract: Proceedings of the First International Conference on Transportation Information and Safety, held in Wuhan, China, June 30-July 2, 2011.
