| 摘 要： | 均衡交通分配模型虽具有结构严谨、结果合理等优点,就目前而言却因为变量多、维数大导致无法很好的求解,从而影响其在实际交通规划中的应用.为了提高交通分配预测的准确性,解决均衡交通分配的求解问题,本文将遗传算法(GA)应用到其中.最后通过一个简例,并利用Matlab的GA工具箱进行编程求解,证明了该方法用于求解均衡交通分配模型的可行性.

| Abstract: | Although the traffic equilibrium assignment model has the precise structure and rational result.But the model can not be solved commendably because of the more variable and large dimension at present;thereby the application in real traffic planning is put down.In order to improve the veracity of the forecasting model,and settle the problem of solving,this paper applies the Genetic Algorithm to the model.Finally specialize a simple example,and then solve the problem in virtue of the GA toolbox of Matlab,which arguing this means of solving traffic assignment is feasible. |
