| 摘 要： | 针对城市交通流量变化产生的问题,在交叉口信号灯配时方案改进的基础上建立了动态路径诱导的双层优化模型,上层模型以行驶时间为目标函数,下层模型以总交叉口延误最小为目标函数。利用改进蚁群算法来求解优化模型,从而获得多准最优路径。以实际交叉口为例,将信号灯配时改进前、后的模型计算结果进行比较。结果表明:应用信号灯配时改进后的模型获得的路径更省时,交叉口等待通行时间更短。

| Abstract: | Aimed at the problem due to changes of the urban traffic flow,based on the improvement of the project of intersections signal lamp,bi-level optimal model of dynamic route guidance was established.In the upper level model,the minimization of travel time was used as the objective function;in the lower level model,the minimization of intersection delay was used as the objective function.Improved ant colony system algorithm(IACA) was applied to solution and improvement of the model,and multi-strip quasi-optimal... |
