“一路一线直行式”公交模式下公交车行驶诱导和调度集成方法

为了充分发挥"一路一线直行式"公交模式的优越性,在车站与路口协同设计与控制的基础上,在交叉口信号配时的约束下,提出一种公交车行车速度优化和诱导、公交车调度的集成方法.该方法根据公交线路各个站点之间的距离、公交车辆的平均行驶速度、各个站点的平均上下客时间,优化公交车辆的行驶速度和发车时间.通过该方法可确保公交车到达有站点的信号交叉口时,利用红灯等候时间上下客;到达无站点信号交叉口时,无需停车,顺利通行,从而避免信号交叉口信号控制对公交车辆通行造成的负面影响,减少公交车在信号交叉口的停车次数和延误.基于概率论分析了该方法的效益,并通过实例说明该方法的可行性.

Novel integrated method of bus speed guidance and dispatching based on "one route one line and run straight mode"

In order to take advantages of the potential of "one route one line and run straight mode",a novel integrated method of bus speed optimization and bus dispatching has been developed based on the design and control in coordination between bus stop and intersection under the restraint of traffic signal timing.This method optimizes travel speed and departure time of bus according to the distances between bus sites,the bus average speed and the average boarding and alighting time,which assures that it is red light when the bus arrives the intersections with bus stops so that the passengers can get up and off during this period,or it is green light when the bus arrives the intersections without bus stops so that the bus can pass through the intersections without stop.This method can avoid negative influence of intersection signal control on bus transit,and reduce effectively the number of stops and delay of the public transit vehicles in the intersections.Its efficiency is analyzed based on probability theory,and its feasibility is illustrated with an example.
