摘要
为避免道路交叉口前需要在交叉口左转的公交车辆在最右侧道路上靠站上下客后,因直行车辆停车等待而阻碍左转公交车辆向左并道的现象发生,探究道路交叉口左转公交车辆预信号控制方法.运用预信号理论,制定预信号条件下最右侧车道及其紧邻直行车道上直行车辆的行驶规则,给出确定预信号、交通标线、交通标志位置的计算公式,并协同预信号与主信号的配时方案.案例分析及仿真验证结果表明,该方法显著地降低了左转公交车辆和直行车辆的延误,并减少了道路交叉口的整体延误.
In front of the road intersection,there are public transport vehicles that need to turn left at the intersection,but they need to stop on the right side of the road to facilitate passengers to get on the bus.At this time,the straight vehicles that stop and wait will block the left turning public transport vehicles from turning left.In order to avoid this phenomenon,this paper explores the pre signal control method of left turning public transport vehicles at the road intersection.Based on the theory of pre signal,the driving rules of the right most lane and the straight vehicles on the adjacent straight lane under the condition of pre signal are formulated,the calculation formulas for determining the location of pre signal,traffic markings and traffic signs are given,and the timing scheme of pre signal and main signal is coordinated.Case analysis and simulation results show that the method can significantly reduce the delay of left turn bus and through bus,and reduce the overall delay of the road intersection.
