Y型交叉口信号控制方法设计与仿真

摘要

针对Y型交叉口的交通问题,以Y型交叉口为研究对象,提出了Y型交叉口交通信号控制方法.该方法对交叉口交通设施、信号控制参数进行设计,以避免各向左转车流之间的冲突.为验证该方法的可行性,采用VISSIM交通仿真软件对Y型交叉口实施信号控制前后进行了仿真分析.仿真结果表明,该信号控制方法能够减少车辆延误,提高了交叉口的通行能力.%A signal control at the Y-intersection was proposed taking consideration of the transportation facilities at the intersection and the parameters of the signal control to avoid the conflict of left turning traffic.The VISSIM-based simulation test was conducted to verify the feasibility of the method.The results showed that the method was feasible to reduce vehicle delay and improve the traffic capacity at intersections.
