摘要
为确定有轨电车客运通行能力,在分析有轨电车运行特征的基础上,以进站清空时间、停站时间和运营裕量为变量,建立了线路通行能力计算模型;通过将交叉口设站时的平均停站时间和红灯平均等候时间之和转换为交叉口平均停站时间,计算无信号协调控制和有信号协调控制的线路通行能力;以不同车长的车辆容量利用系数修正了车辆载客容量,计算得到有轨电车客运通行能力。研究结果表明:无信号协调控制时,客运通行能力为6000~10000p/h;信号协调控制将提升客运通行能力20%~40%,达到8000~15000p/h;交叉口信号周期越长,客运通行能力越低。因此,有轨电车应设置信号优先协调控制,并控制好交叉口规模以降低信号周期时长。
In order to calculate the passenger capacity of tramway,based on analyzing tramway operating characteristics,a line capacity calculation model was established by taking the station clearance time,stopping time and operating margin as variables.Then,via the sum of the average stopping time and the average waiting time at the red light converted into the average stopping time at the intersection,the line capacities with and without signal coordinated control and signal coordinated control were calculated;the passenger capacities of vehicles were revised by the vehicle capacity utilization coefficient of different vehicle length.Finally,the passenger capacities of trams were calculated.The research results show that:when there is no signal coordinated control,the passenger capacity is 6000~10000 p/h;after signal coordinated control,the passenger capacity will be increased by 20%~40%to 8000~15000 p/h;the longer the intersection signal cycle,the lower the passenger capacity.Therefore,tramway should be set with signal priority coordinated control,and the scale of intersections should be controlled to reduce the signal cycle time.
