Abstract:
The problems of existing bus scheduling method such as big interval departure, local convergence and time incoordination were analyzed. The maximum number and maximum bus number arrived at station at the same time were taken as optimization objectives, the fixed departure time of last bus, the allowable queue length of station, service quality and the time span ofroute service were taken as constraint conditions, an optimization method of bus time was built, and the solution algorithm based on network reconnaissance rule and network synchronization rule were designed. Calculation result indicates that when there are two routes and two stations, and departure time is less than 30 min, three synchronizations appear at two stations by using the proposed method. The departure times of route 1 are at 5, 15, 20, 30 min and the departure times of route 2 are at 0, 10, 30 min respectively. Compared with the existing method, the number of synchronization times decreases by one, all departure times completely distribute in given time, surplus time is eliminated, inhomogeneous departure intervals are gotten, and synchronization diversity is reflected. 9 tabs, 6 figs, 17 refs.
