摘　　要：为防止公交串车现象的发生,提高乘客对公交出行方式的满意度,文章提出了一种驻站和限流组合的控制方法。该方法通过分析公交车头的时距偏差获取各站点控制阈值,以车头时距偏差最小和乘客等待时间最短为目标,运用粒子群算法求解站点的驻站时间和限流人数,并基于元胞自动机仿真模型验证此控制方法的有效性,对比分析无控制、驻站控制、限流控制和组合控制的效果。仿真结果表明,基于车头时距偏差阈值的驻站和限流组合的控制策略对于稳定公交车头时距和减少乘客的等待时间具有很强的效果。In order to prevent the occurrence of bus bunching phenomenon and increase the satisfaction of passengers on bus travel mode,the paper proposes a control method combining stagnation and traffic limiting.The proposed method obtains the control threshold of each station by analyzing the time headway deviation,and takes the minimum time headway deviation and passenger waiting time as the target.Particle swarm optimization algorithm is used to solve the stagnation time or the number of current limiting people of the station.Based on the cellular automata simulation model,the effectiveness of the proposed control method is verified,and the effects of no control,stagnation control,current limiting control and combination control are compared and analyzed.The simulation results show that the control strategy based on the combination of parking and f low limiting based on the deviation threshold of bus headway can play a strong role in stabilizing bus headway and reducing passenger waiting time.
