摘　　要：交通流信息诱导能提高区域交通运行效率.本文在区域交通流信息诱导建模理论基础上,基于调研数据,利用VISSIM软件对北京市西南二环内某区域交通进行仿真,对比评价交通流信息诱导措施实施前后的区域道路交通流运行状况,通过5种不同场景分析,结果显示当I.A南进口左转车受诱导量从10%增至30%时,其南进口左转车流旅行时间的降低幅度从18%降至42%,延误从234s降至164s,在保证对区域内其他路段干扰较小的情况下,有效缓解I.A南进口左转车流的拥堵.The traffic flow information guidance can improve the operation efficiency of regional traffic. Based on the information guidance model and survey data, this paper takes advantage of the VISSIM software to simulate the traffic in a region within the Southwest Second Ring of Beijing including 6 roads and 6 intersections, and makes a comparative evaluation on the operation of the regional road traffic flow before and after the implementation of the traffic flow information guidance measures. The analysis of 5 different guided flow cases show that if the guided leftturn traffic flows in southbound I. A increases from 10% to 30%, the travel time of the leg-turn traffic flow in southbound I.A has a reduction from 18% to 42%, and its delay also reduces from 234 s to 164 s. In the circumstance of ensuring less traffic jam on the other sections of this region, the left-turn traffic jam in the southbound I. A can be effectively mitigated.
