Discussion on Urban Traffic Congestion and Countermeasures

Traffic congestion has become one of the common headaches in large cities in China. To develop the effective congestion relief strategies, it is necessary to study the occurrence and scope of traffic congestion. This paper first illustrates the definition, classification, and characteristics of traffic congestion. By categorizing commonly used traffic congestion countermea- sures into four major groups （and 26 sub-types） in reducing trip generation, changing travel distribution in space and time, guid- ing travel mode choice and improving capacity of transportation facilities, the paper discusses the critical problems in developing traffic congestion relieving action plans. Finally, the paper pro- poses to evaluate the performance of traffic congestion counter-measures such as social, environmental, and economic impacts using policy analysis method before implementation in order to avoid making ineffective decisions and to maximize benefits in improving overall traffic flow.
