左转公交专用进口道的设置是实施交叉口公交优先的有效措施之一。合理设置左转公交专用进口道,使之与路段公交专用道相协调,必将大大减小公交运营中的整体延误和出行者的人均延误。本文主要研究在路段已设置公交专用道的条件下,在信号交叉口处左转公交专用进口道的设置方法及适应性分析,并在此基础上提出了左转公交专用进口道的设置条件。

The layout of left-turn bus-only approaches is one of efficient measures of executing bus priority at intersections. The reasonable layout of left-turn bus-only approaches which is corresponded with bus lane on the roadway can reduce the whole delay in the running of buses and the delay per person. Based on the condition that bus lanes have been layout on the roadway, an analysis is made on the layout way and its adaptability of left-turn bus-only approaches at controlled intersections, and layout conditions are presented as well.
