摘　　要：为减小左转车流对T型交叉口通行效率的影响,将一种借用出口道左转的非常规交通组织方法应用于T型交叉口。分析了借道左转交通组织的应用条件;结合T型交叉口的特点,提出了相应的主预信号控制方案;将所提方法应用于北京市一典型T型交叉口,并通过Vissim软件进行仿真运行分析。结果表明:实施借道左转后,交叉口车均延误下降35.18s。In order to reduce the impact of left-turn traffic flow on the efficiency of T-shaped intersections,an unconventional traffic organization method is applied to T-shaped intersections.This paper analyzes the application conditions of the traffic organization of contraflow left-turn lane,combined with the characteristics of T-shaped intersection,the corresponding main pre-signal control scheme is proposed,the proposed method is applied to a typical T-shaped intersection in Beijing,and the simulation operation is analyzed by Vissim software.The results show that the delay of vehicles at the intersection drops by 35.18 seconds after the implementation of turning left and turning left.
