摘　　要：为提高设置可变车道交叉口的通行效率,提出一种基于进口道同向可变车道动态控制的交叉口信号配时优化方法。首先,根据交叉口车辆到达–离去曲线法,对车流欠饱和及饱和两种状态下可变车道的动态控制阈值进行了研究;然后,以提前启亮时间、有效绿灯时间、信号周期和相位最小绿灯为约束条件,以交叉口车均延误时间最小为目标控制,通过MATLAB编制程序,构建了设置可变车道交叉口的信号配时动态优化模型;最后,通过实例采用VISSIM软件进行仿真验证和效果评价。In order to improve the traffic efficiency of the intersection with variable lanes,an optimization method of intersection signal timing based on the dynamic control of the variable lanes of the approach is proposed.Firstly,according to the arrival and departure curve method of vehicles at intersections,the dynamic control thresholds of variable lanes under the conditions of unsaturated and saturated traffic flow are studied;Then,the dynamic optimization model of signal timing for intersections with variable lanes is built by programming MATLAB with the constraint conditions of early lighting time,effective green light time,signal cycle and minimum phase green light,and the objective control of minimum average vehicle delay time at intersections;Finally,VISSIM software is used for simulation verification and effect evaluation through an example.
