【摘要】 交叉口作为城市道路的交通咽喉,其通行效率直接影响到城市整体道路的运行效率。为了提高城市道路交叉口的通行能力等,文章以金华市八一南街—宾虹路为实例,利用VISSIM微观仿真软件分析交叉口的延误时间、停车次数、排队长度以及尾气排放等输出参数,对比信号配时优化前后的方案。结果表明,优化后的交叉口信号配时方案下平均停车延误降低了17.33%,总体停车次数降低了21.13%,平均排队长度降低了36.51%,尾气排放的污染物以及总油耗也有所减少,交叉口的交通状况得到明显改善。更多还原

【Abstract】 As the traffic throat of urban road, the traffic efficiency of intersection directly affects the operation efficiency of the whole urban road. In order to improve the traffic capacity of urban road intersections, this paper uses VISSIM micro simulation software to analyze the output parameters such as intersection delay time, parking times, queue length and exhaust emission, and compares the schemes before and after signal timing optimization. The results show that under the optimized intersection signal timing scheme, the average parking delay is reduced by 17.33%, the overall parking times is reduced by 21.13%, the average queue length is reduced by36.51%, the exhaust pollutants and total fuel consumption are also reduced, and the traffic condition of the intersection is significantly improved.更多还原
