Study on Overpass Plan Based on Micro Simulation Model

采用微观交通仿真模型进行立交方案运行分析,可得到行程时间、速度、延误、排队长度等定量指标,为从交通运行角度研究立交方案提供了一种方法。文章阐述了采用微观交通仿真模型的立交方案分析流程,并结合南宁市某立交方案仿真分析实例,论证了采用该仿真模型进行立交方案交通运行分析的可行性。

With microscopic traffic simulation model adopted to analyze overpass plan opera- tion,the quantitative index such as travel time,velocity, delay and queue length can be ob- tained, providing a method to study overpass plan from the perspective of traffic operation. The article discussed the procedure of analyzing overpass plan by using microscopic traffic simulation model,and taking the simulation analysis of an overpass plan of Nanning City, it verified the feasibility of using this simulation model to analyze overpass plan traffic opera- tion.
