| 摘 要： | 建立双层规划模型用于解决高速公路网的入口流量控制问题。提出了一种结合遗传算法和Aloplex算法的新算法——GAA算法来求解双层规划问题。实验结果表示，GAA算法在求解双层规划问题上优于遗传算法；分车型测算得出进入路网的流量使上层目标函数值更小（相对于单车型情况），并且使路网利用程度得到进一步的提高。

| Abstract: | Aiming at the freeway inflow control problem,the application scenario and solution strategies of bi-level programming model were proposed.The multi-vehicle bi-level programming model was presented to solve the problem on freeway network inflow control.A new algorithm,GAA algorithm,which combined genetic algorithm and Aloplex algorithm was put forward.A simplified example was given to show that GAA algorithm excels to the genetic algorithm in solving bi-level programming problem,calculates the objective value in the case of various vehicle types less than that in the case of simple vehicle type,and improves the utility of expressway network. |
