Abstract

Centralized assigning of bus running between multiple lines can save operation cost of transit agency. As more big transit terminals can serve for multiple bus lines being established, coordinating the operation of these lines’ vehicles becomes more economical and perspective. This paper proposed a vehicle-scheduling model for multiple lines which share vehicle resource together and service based on the same terminal. The optimization goal is to minimize the number of vehicles while considering reducing the invalid operation time under the constraint of timetable schemes and matching time for vehicle crossing two lines. A case in Ningbo city, China, was conducted to compare the performance of the cross-line schedules with the original schedules assigning vehicles within respective lines. The optimized schedules can reduce 7.14% vehicles in need while meeting the timetable schemes of all bus lines, which indicated that the proposed model is suitable for operation practice.
