摘要: 借道左转是平面交叉口左转交通组织方式之一。分析借道左转的设置参数,确定“借道”长度、“借道”车道数的取值范围以及设置借道左转的约束条件,并从道路、交通、信号控制三方面确定适用条件;以一实际交叉口为例进行分析,运用VISSIM软件对其加设借道左转前后的进口道相关指标进行仿真评价,优化借道左转的配时方案,并验证此交叉口设置借道左转车道的可行性以及优势,证明借道左转使交叉口延误降低。研究成果为城市道路交叉口的借道左转设置方案提供决策依据。

Abstract: Contraflow left-turn is one of the traffic organization ways at intersections. By analyzing the setting parameters of the contraflow left-turn, the length and the range of the contraflow left-turn lane, the constrained conditions of the contraflow left-turn are determined, and the applicable conditions are determined from the road, traffic and signal control. VISSIM software is used to analyze a road intersection, simulate and evaluate the indicators related to the intersection entrance, optimize the timing plan of contraflow left-turn lane, and validate the feasibility and advantages of contraflow left-turn lane. The results show that the intersection delays are reduced by contraflow left-turn lane, which provides experiences and fundamental reference for the setting of contraflow left-turn lane.

Key words: traffic organization, contraflow left-turn, intersection, traffic simulation, delay
