基于VISSIM仿真的交叉口优化方案研究——以苏州市吴江区运东大道——东太湖大道交叉口为例

Research on Intersection Optimization Scheme Based on VISSIM Simulation——Take the Intersection of Yundong Avenue and East Taihu Avenue in Wujiang District, Suzhou City as an Example

由于路口通行能力受到用地紧张、施工对通行能量影响较大等因素的影响,交叉路口的通行能力近年来屡受诟病。扩建路口、实施单行等一系列管理措施并不能短时间内缓解路口的通行压力。文章选取了苏州市吴江区运东大道—东太湖大道交叉口为例,在对交叉口现状进行分析后,设计了近、远期两套优化方案,并基于VISSIM对优化方案进行仿真。

Because the traffic capacity of intersections is affected by factors such as tight land use and greater impact of construction on traffic energy, the traffic capacity of intersections has been criticized repeatedly in recent years. A series of management measures such as the expansion of intersections and the implementation of single lanes cannot alleviate the traffic pressure at the intersection in a short time. This paper selects the intersection of Yundong Avenue and East Taihu Avenue in Wujiang District, Suzhou city. After analyzing the current situation of the intersection, two sets of optimization schemes are designed for the near and long term,and the optimization scheme is simulated based on VISSIM.
