The invention discloses a trunk line intelligent network connection bus speed and signal timing collaborative optimization method, which comprises the following steps: acquiring basic information of bus lines, such as departure time interval, line length, station distribution and intersection signal phase; an intelligent networked bus speed control model is constructed, and dynamic speed guidance is implemented for different deviation types by calculating the deviation of the time headways of adjacent vehicles in real time; based on a vehicle speed control result, intersection signal lamp timing is optimized, and the negative influence of traffic signals on the driving speed of the public transport vehicle is reduced. By implementing accurate speed and signal lamp cooperative control at each bus station and intersection, the method can improve the overall operation efficiency of the trunk bus system to the maximum extent and reduce intersection delay while ensuring that the buses arrive on time, and compared with a traditional whole-line adjustment strategy, the method has the advantages that the overall operation efficiency of the trunk bus system is improved to the maximum extent, and the cost is reduced. According to the control strategy, the problem that the time headway deviation of a local road section is large can be solved more accurately.

    本发明公开了一种针对干线智能网联公交车速与信号配时协同优化方法,采集公交线路的基本信息,如发车时间间隔、线路长度、站点分布及交叉口信号相位;构建智能网联公交车速度控制模型,通过实时计算相邻车辆车头时距的偏差,针对不同偏差类型实施动态速度引导;基于车速控制结果,优化交叉口信号灯配时,降低交通信号对公交车辆行驶速度的负面影响。通过在每个公交站点和交叉口实施精准的速度与信号灯协同控制,本方法能够在保证公交车辆准时到达的同时,最大化提高干线公交系统的整体运行效率,减少交叉口延误,与传统的全线调整策略相比,本发明的控制策略能够更精确地应对局部路段车头时距偏差较大的问题。
