【摘要】 城市快速公交(BRT)具有容量大、方便快捷、安全性能高、建设周期短、造价及运营成本相对低廉等特点,是解决城市交通拥堵难题的有效手段,也是未来城市智能公共交通系统发展的方向之一。本文针对BRT线路中公交优先的预信号评估问题展开研究,将型号类型界定为Ⅰ、Ⅱ两种,提出了配时参数的计算方法,对两种信号控制方式下车辆的延误进行了建模,案例分析结果表明控制公交车进入优先区域的预信号对交叉口信号控制不利,Ⅱ型控制方式下车辆延误较Ⅰ型大,建议城市BRT工程项目中采用I型预信号。
【Abstract】 Priority signal control method of BRT: pre-signal, inductive signal for bus priority and signal with bus priority phase. Before implementing the engineering, cross to carry on the design and valuation towards pre-signal, in order to draw up a superior the project of bus priority of the intersection. This paper addresses these points through the development of analytical procedures which allow pro-implementation evaluation of two specific categories of pre-signals. As a result explain,it is disadvantageous that control the bus enters to priority area for priority signal control, suggest to adopt I type pre-signal in the actual engineering。
