摘要：

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 left-turn traffic flows in southbound I. A increases from 10% to 30%, the travel time of the left-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.
