摘　　要：针对城市道路错位交叉口几何线形及交通组织的特点,考虑转弯半径对交叉口车辆运行的影响,通过VISSIM仿真软件建立了错位交叉口几何参数与运行参数的关系模型,提出了两种适用于错位交叉口的信号控制方案,并以长沙市曙光南路-劳动中路-曙光中路形成的错位交叉口为研究对象,通过VISSIM软件进行仿真验证与对比分析。研究结果表明:行驶速度和饱和流率随交叉口转弯半径的增大而增大;行车延误随交叉口转弯半径的增大而减小;对于近距离错位交叉口,对饱和流率进行折减后采用协调控制可以减少车辆的平均延误,提高交叉口的通行能力和服务水平。In view of the characteristics of the geometric alignment and traffic organization of the urban misaligned intersection,considering the influence of the turning radius on the vehicle operation at the intersection,the relationship model between the geometric parameters and the operating parameters of the misaligned intersection is established through the VISSIM simulation software,and two signal control schemes are proposed.After that this paper takes the misaligned intersection formed by Shuguang South Road-Labor Middle Road-Shuguang Middle Road in Changsha as a case study,and the simulation verification and comparative analysis are carried out by VISSIM software.The research results show that:the driving speed and saturation flow rate will increase with the increase of the turning radius;the driving delay will decrease with the increase of the turning radius;for the misaligned intersection,the coordinated control after reducing the saturation flow rate can reduce the average vehicle delay and improve the capacity and service level of the intersection.
