Abstract: To analyze the headway optimization theory about urban public transport.The optimization of transit operation parameters such as headway is a very important task in APTS.The paper establishes a new model based on the maximum of the overall social benefit.Because so many variables are involved in the model，the traditional optimization method is infeasible to solve it.This paper proposes a new method to optimize those parameters using Genetic Algorithm（GA）.The method mentioned in this paper is applied to the actual urban transit operations of two public transportation routes in Changchun City.

Key words: genetic algorithm, intelligent public transport dispatching, headway
