摘要
传统借道左转应用方式为直接借用一定长度对向出口车道供本向左转车辆使用,以此缓解左转车道交通压力,提高路口交通通行效率。而在对向出口道通行能力不足的情况下,若本向进口道左转车道通行能力尚有剩余,亦可考虑利用借道左转思维解决问题。通过对借道左转设置的条件进行研究,提出一种新型借道左转应用方法,将本向左转车道借给对向出口车道进行共用,使道路资源得到充分利用,并基于广州市东风东路农林下路路口应用实例,分析该应用方法的有效性。
The traditional application of contraflow left-turn lane is borrowing some length of the exit lanes for left-turn directly, to ease the traffic pressure of left-turn lane and improve the traffic efficiency of intersection.However, if the capacity of exit lanes is not enough, and the capacity of entrance left-turn lanes has remained, the thought of contraflow left-turn lane can also be used to solve this problem.By studying its situation, a new application of contraflow left-turn lane is proposed.Through borrowing the left-turn lane as a exit lane, the effect of road resources utilized is realized.By the applicational example of the Dongfeng East Road and Nonglinxia Road intersection in Guangzhou, the effect of the application is analyzed.
