摘要
针对城市交通供需系统的复杂性和动态性特点,构建基于系统动力学的城市交通供需非均衡仿真模型。采用VENSIM软件进行模拟分析,研究城市交通供需非均衡的形成机理和发展趋势。改变模型中的相关政策变量,进行政策试验,观察其仿真效果并提出调控措施,从而缓解日益突出的城市交通供需矛盾。
Aiming at the complexity and dynamic characteristics of urban traffic supply and demand system, a simulation model for disequilibrium of urban traffic supply and demand is set up by using flow diagram, then the formation mechanism and development trend of traffic supply and demand disequilibrium are simulated by using VENSIM soft- ware.The polices of the variables in the model are changed.The policy experiments are carried out and the simulation effects are observed. The increasingly prominent contradiction between the supply and the demand of urban traffic are put forward.
