研究通过调整城市轨道交通网络中换乘站各方向列车的离站时刻及换乘站间列车运行时分,实现减小乘客的换乘等待时间问题。分析单个换乘站乘客的换乘过程,得出乘客总换乘等待时间的计算方法。针对在网络化运行环境下换乘站之间列车离站时刻存在相互影响的问题,提出通过调整运行时间以实现协调优化的策略。以整个网络乘客总换乘等待时间最少及换乘站间列车运行时间调整最小为目标建立双目标优化模型。根据模型特点,设计了非支配排序进化算法(NSGA-Ⅱ)。通过案例分析,利用算法完成了模型求解。计算结果表明,模型能有效减少乘客换乘等待时间。
By adjusting the departure time of train and the train operation time between transfer stations in all directions of the transfer station in the urban rail transit network, the study aims to reduce the waiting time for transfer passengers. The transfer process of passengers in a single transfer station is analyzed to get the calculation method of the total transfer waiting time of passengers. In order to solve the problem of interaction between trains and stations during the networked operation, this paper proposes a strategy of adjusting the running time to achieve coordination and optimization. The objective is to set up a dual-objective optimization model with the goal of minimizing the total waiting time of passengers in the whole network and minimizing the train running time between transfer stations. According to the characteristics of the model, a non-dominated ranking evolutionary algorithm (NSGA-Ⅱ) is designed. Through case analysis, the algorithm is used to solve the model. The results show that the model can effectively reduce the passenger waiting time.
