基于人均延误的有轨电车信号优先控制方式选择

Selection of signal priority control mode for tramways based on per capita delay

在有轨电车主动优先模式下,以交叉口车均延误计算公式和车均载客量为基础,得到交叉口人均延误计算公式,并推出各信号优先控制方式下的人均延误计算公式。运用最优化理论,得到有轨电车不同到达时刻的信号优先方式选择方案,并提出了信号损失相位的弥补方法。最后以苏州市有轨电车一号线何山路与金枫路交叉口进行了实例论证,结果表明该信号控制方式选择方案在使交叉口人均延误最优上具有一定的优越性。

Under the active priority mode of tram,the formula for calculating average vehicle delay at intersections is obtained based on the formula for calculating average vehicle delay at intersections and the passenger volume per vehicle,and the formula for calculating the per capita delay under each signal priority control mode is also derived.Using the optimization theory,the signal priority mode selection scheme of tramway at different arrival times is obtained,and the signal phase compensation method for tramcar signal priority control mode is given.Finally,a case study of the intersection of He Shan Road and Jinfeng Road on the No.1 tram line in Suzhou City is carried out,the results show that the selection scheme of signal control mode has certain advantages in optimizing the per capita delay at intersections.
