摘  要:公交桥接是应对城市轨道交通非计划中断的常用方法,它需要管理者在短时间内调度足够数量的公交车至中断站,以减轻滞留旅客延误。针对这一应急公交实时调度问题,提出一个灵活的调度策略,同时调度备用车和开行中的公交车作为应急公交,以共同承担公交桥接任务。考虑到对原公交用户的影响,本文基于网络流理论,以地铁和公交乘客总延误最小为目标,建立了一个可精确求解的线性规划模型,以上海市中断实例验证模型的可行性。结果表明,模型可在短时间内精确求解,满足应急响应需求。与仅从驻车点调取备用车作为接驳公交的传统调度策略对比,在最优的情况下,本文提出的调度方法可使滞留旅客平均等待时间减少约81%,显著提高了公交桥接输运效率。Bus bridging strategy is a common solution to the unplanned disruptions of urban rail transit systems,which requires operators to dispatch the number of buses to the disrupted station at short notice to mitigate delays for stranded passengers.To address this problem,a flexible dispatching scheme was proposed to dispatch both spare buses and running buses in service as shuttle buses to share the bus bridging task.Considering the impact on the original bus users,a linear programming model was built for the bus dispatching method based on network flow theory,with the objective of minimizing the total delay of metro passengers and bus passengers.Case studies based on the data sets in Shanghai were conducted.The results demonstrate that the approach can be carried out in real time.Moreover,compared to the traditional dispatching strategy of dispatching spare vehicles from parking lots as shuttles,the method can reduce the average waiting time of stranded passengers by about 80%in the optimal case,significantly improving the efficiency of the bus bridging strategy.
