摘　　要：公共交通是提高城市出行效率,缓解城市拥堵的手段。提高公交车的使用率,要提高公交车辆的服务水平,最直接有效的方法便是提高公交运行效率、减少延误。本文主要对公交优先感应信号的设置方法进行研究,提出公交车在通过检测器时可能遇到的5种情况,然后详细分析了3种优先方式的基础,对感应线圈的布设位置进行探讨与建模,以此达到既能实现公交优先,又能满足尽量减少对其余社会车辆影响的要求。最后结合VISSIM,绿灯延长模型进行仿真,检验模型的有效性。结果显示,绿灯延长能够缓解交叉口的拥堵,并提高了交叉口的通行效率。Public transportation is a means of improving the efficiency of urban travel and alleviating urban congestion. To improve the utilization rate of buses, the most direct and effective way to improve the service level of public transportation vehicles is to improve the efficiency of public transportation operations and reduce delays. This paper mainly studies the setting method of bus priority sensing signal, and proposes five situations that the bus may encounter when passing the detector. Then it analyzes the basis of three priority modes in detail, and discusses the location of the induction coil. It can achieve the priority of public transport, and meet the requirements of minimizing the impact on the rest of the social vehicles. Finally, combined with VISSIM, the green light extension model is simulated to verify the validity of the model. The results show that the green light extension can alleviate the congestion at the intersection and improve the traffic efficiency of the intersection.
