摘　　要：交通仿真是设计、分析和评价交通方案的重要技术方法。重点介绍微观交通仿真软件中的Synchro与VISSIM软件。选取上海市某单点交叉口,针对无法利用VISSIM软件对原有交叉口交通信号配时方案进行优化的缺点,先利用Synchro中的信号配时优化功能对交叉口信号配时进行优化,然后再对交叉口进行交通仿真评价。仿真结果表明,利用Synchro对交叉口信号配时进行优化后,交叉口运行效率好于未进行信号配时优化时的运行效率,此方法具有较好的工程实用性与推广意义。Traffic simulation is an important technical method to design, analyze and evaluate traffic scheme. Microscopic traffic simulation software, Synchro and VISSIM, were introduced in this paper. We chose one isolated intersection in Shanghai, and con- sidered that intersection traffic signal timing optimization couldn＇t be carried out in VISSIM software. Firstly, signal timing was opti- mized by signal timing optimization module in Synehro, and then traffic evaluation was executed in VISSIM. Simulation results show that after signal timing optimization, intersection operation efficiency is better than that of original signal timing, so the proposed method possesses good engineering practicability and popularization significance.
