Method of Cross-Line Timetable Optimization Based on a Single Depot for Cluster Scheduling

Public transportation companies generally establish a scheduling command center, and gradually develop the mode of cluster scheduling in large-sized and medium-sized cities in China. Realizing the mode of “multiple lines and a scheduling center” is one of the advantages of cluster scheduling so that it can improve the utilization of transport capacity resources. Based on the background, the paper studies a method of cross-line timetable coordinated optimization under cross-line buses with single depot, the synchronization timetable model of which not only considers the decrease of the total passengers’ time cost, including the time cost of cross-line transfer passengers and non-cross-line waiting passengers, but also optimizes the buses’ arriving time and buses’ departure time in order to facilitate to link up the different trips. In addition, the paper established a model of seamless transfer timetable, which effectively reduces the waiting time and the cross-line transfer walking distance of cross-line transfer passengers.
