A comprehensive optimization model of the departing time interval includes an optimization model and a smooth transition model. The optimization models of the departing time interval based on the average passenger flow and the maximum sectional passenger flow are constructed respectively. The optimization objective of the former model maximizes the transit capacity to fit travel demand while the optimization objective of the latter minimizes the operation cost of the public transit company ensuring the profit of passengers. In the paper,the smooth model of the departing time interval is constructed to solve the departing time interval and compile the departing schedule of the public transportation. The model is solved by using the integral programming and it is tested by the example. The results show that the model can effectively improve the operational efficiency of public transport,and it has a better practicability.
