【摘要】：针对交叉口出口道时空资源利用不高的问题,以进口道公交左转优先为目标,提出了一种基于现有道路条件下的逆向可变车道及左转公交专用道设置方法从而实现了公交车辆的左转优先。分析了上述两种车道交叉口需满足的实施条件,并对车道进行设计,提出了相应的信号控制方法,最后结合设计案例,利用VISSIM软件对比分析了逆向可变车道设置前后交叉口的运行效果。仿真结果表明:设置后的管理方法能有效地降低本进口左转公交的车均延误及提高其通行量,且不影响交叉口其他方向车辆的正常通行,从而验证了本方法的有效性,为实现公交左转优先和减少出口道资源浪费提供了新的思路与方法。
[Abstract]:In view of the problem of low utilization of space-time resources at intersections exit lanes, the target is to give priority to the left turn of public transportation in the entrance lanes. In this paper, a method of setting the reverse variable lane and the left-turn bus lane is proposed based on the existing road conditions, so that the left-turn priority of the public transport vehicle can be realized. This paper analyzes the implementation conditions of the above two kinds of lane intersections, designs the lanes, puts forward the corresponding signal control methods, and finally combines with the design cases. The operation effect of the intersection before and after the setting of the reverse variable lane is compared and analyzed by using VISSIM software. The simulation results show that the management method can effectively reduce the average delay and increase the traffic volume of the imported left-turn bus, and does not affect the normal traffic of other directions of the intersection, thus validating the effectiveness of this method. It provides a new way of thinking and method for realizing the priority of public transport turning left and reducing the waste of exit resources.
