基于VISSIM仿真的信号交叉口优化研究

摘要

A road intersection is an important component of urban road system.We investigate the road intersection at Jinan Erhuan East Road and Shanda North Road.We also employ VISSIM to simulate,analyze and assess its current situation.Traffic delay and queue length are effectively decreased by such road intersection optimization as channelizing and signal scheduling adjustment,so its traffic capability is significantly increased.%交叉口是城市道路系统中重要的组成部分.本文对济南二环东路与山大北路交叉口进行实地调查,采用VISSIM仿真软件对交叉口现状进行仿真、分析与评价.通过交叉口渠化、信号配时调整等措施,有效地降低了车辆的延误和排队长度,从而大大提高了道路的通行能力.
