摘　　要：公交车头时距的均衡性是衡量公交运行可靠性的重要指标,对于提高公交服务水平、增强公交吸引力具有重要意义。本研究针对车路协同环境下公交车头时距的控制问题,融合公交信号优先、公交驻站时间控制、车速引导等多种控制手段,以公交车车头时距均衡性为主要优化目标,建立多线路公交控制优化模型,对公交车实现全线路实时动态的精准控制。保证公交车车头时距均衡的同时,尽量减少公交车的总体延误以及对其他社会车辆的影响。以深圳市福田中心区的M390路公交线路为例,利用VISSIM对模型进行仿真验证分析,结果表明,本研究建立的基于车头时距的多线路公交动态控制优化模型能够在对其他社会车辆影响较小的情况下,实现车头时距均衡性提升84%,公交车的总体延误降低12%。The regularity of the bus headway is an important indicator to measure the reliability of bus operation,and it is of great significance for improving the level of bus service and enhancing the attractiveness of the bus.Aiming at the control problem of bus headway distance in anintelligent vehicle infrastructure cooperative environment,this study combines multiple control methods such as bus signal priority,bus stop time control and speed guidance,and takes bus headway regularity as the main optimization goal to establish The multi-line bus control optimization model realizes real-time dynamic and precise control of the bus on all lines.While ensuring a regular headway of the bus,the overall delay of the bus and the impact on other social vehicles should be minimized.Taking the M390 bus line in the central area of Futian,Shenzhen as an example,using VISSIM to simulate and verify the model,the results show that the multi-line bus dynamic control optimization model based on the headway established in this study can have a little impact on other social vehicles,theheadway regularity is increased by 84%,and the overall delay of buses is reduced by 12%.
