Abstract:In order to coordinate transportation capacity among overlap bus lines on passenger corridor,a bus coordination dispatching mode is put forward. And the corresponding bus headway optimization model is set up, which takes the maximum service efficiency of passenger corridor as the optimization goal,and the capacity of transit infrastructure and service level of passenger transport as the constraints. After the primal problem being transferred into a combinatorial optimization problem,genetic algorithm(GA) is designed to solve it.The practical case application shows that this method is benefit for intensively deploying transportation capacity of passenger corridor.
