城市客运走廊公交行车间隔协调优化方法

Coordinated Optimization of Bus Headway for Passenger Corridor

为协调城市客运走廊公交线路运输能力,提出了一种公交线路协调调度模式,建立了以客运走廊运输服务效率最大化为目标、以公交基础设施通行能力限制和客运服务水平条件为约束的公交行车间隔优化模型.原问题转化为组合优化问题后,采用遗传算法进行求解.案例应用结果表明该方法有利于集约化配置客运走廊公交运能资源.

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.
