摘要
分析了城市交通拥挤的形成机制，建立了城市交通拥挤问题的系统动力学模型。以Vensim为平台，利用该模型预测了上海市2007-2020年的人口、交通和拥挤程度等的发展趋势，并探寻各子系统的互动模式和内在机制。
Traffic congestion is an outcome of interaction between physical facilities and complicated social economic system. The mechanism to form the traffic congestion was analyzed. A system dynamics model for traffic congestion problem in cities was developed. Based on the Vensim, the traffic congestion problem was simulated. As a case study, the future trend of population, transportation, and traffic congestion was forecast for 2007-2020 in Shanghai. The inherent mechanism and mutual relationship among each subsystem in traffic congestion problem were also analyzed.
