摘要:
为提高有轨电车在平交路口的通行效率，提出一种有轨电车实时信号优先控制方法。根据有轨电车到达时刻所处相位情况划分4种工况；结合信号相位相序与有效绿灯时间，提出电车相位早启与延长控制策略；根据非电车相位压缩约束限制，建立电车相位实时绿灯时间模型。最后，应用南京市江东中路奥体大街平交路口实测交通数据，建立Vissim交通仿真环境，对所提方法的实施效果进行检验。验证结果表明,基于运行效率最优的有轨电车信号优先控制方法能有效提高有轨电车在平交路口处的通行效率。
Abstracts:
In order to improve the passing efficiency of tram at intersections, a tram real-time signal priority control method is proposed. According to the signal phase when tram arrives at the intersection, 4 working conditions are drawn. According to the signal phase order and effective green-light time, advanced and extended control strategy of tram phase is proposed. According to the non-tram phase constraints, the tram phase real-time green-light time model is established. At last, the data collected from the intersection of Jiangdong Middle Road and Olympic Street in Nanjing is applied to construct Vissim traffic simulation environment, and the effectiveness of the proposed method in implementation is verified. Result shows that the tram signal priority control method based on optimal operation efficiency can effectively improve tram passing efficiency at intersections.
