摘　　要：为提升多岔路口的通行能力,解决当前已有方法存在的行程延误时间和车辆排队时间较长等问题,提出了一种基于VISSIM仿真的多岔路口信号灯智慧控制方法。从我国混合交通流的特点出发,调查多岔路口的交通流量以及延误情况等,采用交通流理论分析多岔路口交通流通情况,通过交通模拟软件VISSIM进行仿真模拟,找出拥堵路口;然后对其进行配时改进,获取最佳多岔路口信号灯智慧控制方案。最后进行仿真实验测试,实验结果表明,所提方法能够有效降低延误时间,提升城市多岔路口的通行能力。Because the current existing methods have problems such as long travel delay time and long queue time of vehicles,a smart control method of multi-fork traffic lights based on VISSIM simulation is proposed.Starting from the characteristics of mixed traffic flow in our country,the propoesd method investigates the traffic flow and delays at multiple fork junctions,uses traffic flow theory to analyze the traffic flow at multiple fork junctions,and uses traffic simulation software VISSIM to simulate and find congested junctions,and improves timing to obtain the best intelligent control scheme for multi-fork signal lights.Finally,a simulation experiment test is carried out.The experimental results show that the proposed method can effectively reduce the delay time and improve the traffic capacity of the city's multiple forks.
