摘要
平交路口处左转交通产生的冲突点最多,对直行车流通行的干扰最大,使得平面交叉口交通延误增大.现代有轨电车车道布置形式主要有中央布置、两侧布置以及单侧布置3种,不同车道布置形式对左转交通的影响程度有所不同.本文在实地调查青岛城阳现代有轨电车的基础上,选取典型平交路口进行仿真分析,通过调节左转与直行交通比例,从交通延误、排队长度以及行驶平均速度的角度出发,探讨现代有轨电车在交叉口处,不同车道布置形式在不同交通比例下对左转交通以及整个交叉口的影响,从而明确其适用范围,为我国城市发展现代有轨电车提供参考.
The left-turn traffic flow,which leading to the most conflict point at the intersection,is harmful to the straight traffic and the operating efficiency of the intersection. The lane arrangement of the modern tram could be divided into three parts: in the center,on both sides and one side of the road. The arrangement is also having different impacts on left-turn traffic. The objective of this paper is to analyze the impact of diverse lane arrangement of the modern tram on the left-turn traffic. Then a typical intersection is selected to analyze the Chengyang modern tram in Qingdao with simulation. Additionally,the application scope of the lane arrangement is obtained using the delays,queue length and average speed by adjusting the percentage of straight and left-turn traffic. The study could be viewed as a reference for the development of the modern tram in other cities.
