Study on Departing Time Interval control of Bus Dispatching

The key problem of designing the operation schedule for public transit lines is to determine the departing time interval. Through studying on influence factors in bus dispatching and passenger flow variety rule in public transit lines, this paper provides a model of controlling departing time interval, which considers both generalized trip cost of passenger and bus enterprise operation cost. The model and algorithm is validated by the scheduling data of No.5, the bus demonstration route of Tianjin.
