摘要
设置逆向可变车道目的在于保证交叉口通行能力的条件下缓解进口道左转车辆的交通压力.本文提出了一种基于感应控制的逆向可变车道方案.针对逆向可变车道的感应控制方案提出了参数设计方法并进行了延误分析.利用VISSIM的VAP模块对感应控制方案进行了仿真实验,分别对定时控制以及感应控制方案进行了效益评价.分析了感应控制方案分别在不同流量以及不同左转比例下的运行效果.结果表明,方案在不同流量下均能使主路左转车辆的通行效率得到有效提高,随着流量增大,感应控制下交叉口整体延误逐渐接近定时控制.当逆向可变车道所在进口道左转比例较高时,感应控制方案能发挥出更好的效果.提出的方案能够保证交叉口整体通行效率的同时提高主路左转的通行效率,进一步提高交叉口的时空利用率,为交叉口时空资源优化提供了新的思路方法.
The reverse variable lane aims to relieve the traffic pressure of the left turning vehicle without the detriment of intersection capacity. A reverse variable lane scheme based on actuated signal control is proposed in this paper. The parameter design and delay analysis are proposed for the actuated control scheme of reverse variable lane. The VAP module of VISSIM was used to simulate the actuated control scheme,and the efficiency evaluation was carried out on timing control and actuated control scheme respectively. The operation effect under different vehicle volumes and different left-turn ratio is analyzed. The simulation results show that the scheme can make the left-turn vehicles travel more effectively under all the volume plan. But with the increase of the vehicle volumes,all approach vehicles’ delay of actuated control scheme approach to that of timing control scheme gradually. Besides,the actuated control scheme has a better effect under a higher left-turn ratio. Thus,the actuated control scheme can improve the traffic efficiency of leftturn vehicles at main road and ensure the efficiency of the whole intersection traffic at the same time. The utilization of space and time can be raised by this,and it provides a new idea and method for the optimization design of space-time resource at intersections.
