摘要
为减少串车现象以提高公交服务可靠性,提出了一种基于车头时距阈值的驻站—限流的组合公交策略.为了验证新策略的有效性,基于元胞自动机模型建立了可描述公交车运行特征和乘客出行特性的仿真框架,并利用实际的公交线路数据对其参数进行了校验.数值实验分析了组合策略中控制参数的取值对系统性能的影响.结果表明,以最小化乘客平均等待时间为目标所求解的组合策略有助于公交系统服务可靠性的提高,而最小化单位乘客出行时间时所求解的策略具有更高的乘客出行效率和公交运行速度.
To reduce bus bunching and improve service reliability,this paper proposes a headway-based threshold integrated bus control strategy,which combines holding with limited boarding.To evaluate the strategy in a systematic manner,a simulation framework based on cellular automata has been developed to depict the operations of buses and the activities of passengers,and the parameters involved are calibrated by data from a real-life bus route.In the simulations,we analyze the influences of control parameters on different performance measures.The results show that,when minimizing passenger average waiting time,the obtained integrated strategy has a greater ability to improve service reliability;while it performs higher passenger travel efficiency and bus operating speed,when minimizing passenger average travel time.
