摘　　要：通过对和平大道-建设二路十字交叉口进行现场调查,获得交叉口高峰及平峰期的交通特征参数,据此分析并计算信号交叉口通行能力及交叉口服务水平。应用微观仿真软件VISSIM建立模型,采用改变信号配时、重新设置交叉口渠化方案等方法,对原行人过街问题较严重的交通控制方案进行改进、仿真和优化,以为进一步开展交叉口仿真研究及现有交叉口优化设计提供借鉴。Based on field investigation for intersection of Heping Avenue-Jianshe No.2 Road,this paper obtains traffic characteristic parameters at the intersection in rush hours and mean time,and accordingly analyzes and calculates traffic capacity at signal intersection and service level at intersection.The paper establishes model by means of microscopic simulation software VISSIM and adopts methods of changing signal timing and resetting highly channelizing scheme,etc.to improve,simulate and optimize the original traffic control plans with serious pedestrian crossing problems to as to provide a reference for further development of simulation study of intersection and optimized design of existing intersection.
