OD-Dependent Train Scheduling for an Urban Rail Transit Network

In the previous two chapters, we have discussed the train schedulingproblem for a single urban rail transit line with OD-independent and OD-dependent passenger demands. In the current chapter, we consider the train scheduling problem for an urban rail transit network, i.e., a collection of interdependent transit lines. An event-driven model is built for train scheduling, which involves three types of events, i.e., departure events , arrival events , and passenger arrival rates change events . The routing of the arriving passengers at transfer stations is formulated in the train scheduling model. Furthermore, the passenger walking time and the passenger transfer process are also taken into account in the train scheduling model. The resulting optimization problem is a real-valued nonlinear nonconvex problem, which can be solved by nonlinear programming approaches and evolution algorithms. The performance and the effectiveness of the event-driven model are evaluated via a case study. This chapter is based on Wang et al. (Transp Res Part C 60: 1–23, 2015) .
