The invention discloses a bus operation interval speed optimization control method and system based on multi-objective optimization. The method comprises the steps: acquiring the real-time position and speed information of a bus, the position of a downstream station and the position information of an intersection; with the bus operation punctuality as the most important target, solving an optimalsolution set meeting the bus operation punctuality based on the obtained information; and with bus operation fuel economy as a secondary important target, solving the optimal speed of bus operation based on the optimal solution set, and guiding the operation of the bus. A bus operation target is divided into two levels of punctuality and fuel economy according to importance, a bus arrival punctuality area judgment model is used for judging speed-time-position characteristics in bus operation, and bus operation interval speed optimization suggestions are obtained through a multi-target optimization model.
本发明公开了一种基于多目标优化的公交运行区间速度优化控制方法及系统,包括:获取车辆实时位置、速度信息、下游站点位置以及交叉口位置信息;以公交运行准点性为最重要目标,基于获取到的信息求解满足公交运行准时性的最优解集;以公交运行燃油经济性为次重要目标,在所述最优解集的基础上,求解公交运行的最优速度,指导公交车辆的运行。本发明将公交运行目标根据重要性分为准点性和燃油经济性两个层级,并利用公交到站准时性区域判断模型对公交运行中的速度‑时间‑位置特性进行判断,通过多目标优化模型得出公交运行区间速度优化建议。
