摘要
交叉口是路网的重要节点,优化交叉口信号配时方案是提高其通行效率的有效措施。文中以焦作市塔南路与工业路信号交叉口为例,优化设计交叉口信号配时方案,并建立VISSIM9.0仿真模型,从交通效率和尾气排放量两方面对交叉口信号配时优化前后的仿真结果进行综合评价。结果表明:在交通效率方面,优化后的交叉口车均延误降低了15.26%,平均停车延误降低了18.12%,车均排队长度减少了23.45%,平均停车次数降低了2.75%;在尾气排放量方面,污染物(CO、NOx、VOC)总排放量和油耗总量均减小了6.79%,交叉口的交通状况得到明显改善。
Intersection is an important node of road network,and optimizing intersection signal timing scheme is an effective measure to improve its traffic efficiency.In this paper,taking the signalized intersection of Tanan Road and Industrial Road in Jiaozuo City as an example,the signal timing scheme of intersection is optimized,and the VISSIM 9.0 simulation model is established to evaluate the simulation results before and after signal timing optimization from two aspects of traffic efficiency and exhaust emission.The results show that in terms of traffic efficiency,the optimized intersection vehicle delay is reduced by 15.26%,the average parking delay is reduced by 18.12%,the average queue length is reduced by 23.45%,and the average parking times is reduced by 2.75%.In terms of exhaust emissions,the total emissions and fuel consumption of pollutants (CO,NOx,VOC) have been reduced by 6.79%,and the traffic conditions at intersections have been significantly improved.
