Abstract: Limited by urban road red line, many bus stops can only set up linear bus stop, whose platform is prone to cause traffic congestion, queuing, and motor vehicle conflicts. Based on this, an optimization scheme for shared overtaking lane (SOL) sensing signal control was proposed, and the delay level of vehicles before and after sharing overtaking lane was simulated and analyzed by VISSIM software. The research results show that setting up SOL can effectively alleviate traffic congestion, queuing, and motor vehicle conflicts at bus stops. Under the condition of large traffic volume and high bus departure frequency, the level of public transportation service can be effectively improved by setting the linear bus stop with shared overtaking lanes, which ensures priority passage of buses and orderly passage of social vehicles in the upstream section of near road intersections and improves the smoothness and safety of traffic flow.

摘要： 受城市道路红线条件限制，许多公交车站只能设置直线式公交站台；这种形式的站台很容易产生拥堵排队和机动车冲突的交通现象。基于此，提出了一种共享超车道感应信号控制的优化方案，使用VISSIM软件对共享超车道前后车辆的延误水平进行了仿真分析。研究结果表明：通过设置共享超车道能有效地缓解公交车辆在公交站点拥堵排队和机动车冲突的交通现象；在交通量较大和公交发车频率较高情况下，通过设置带有共享超车道的直线式公交站台能有效地提升公交服务水平，保障近道路交叉口上游路段的公交优先通行和社会车辆有序通行，提升了交通的流畅性与安全性。
