| 摘 要： | 以城市噪声环境容量为约束条件计算城市区域路网最大交通承载力。分析模型是一个双层优化问题，其中上层是噪声环境容量约束下的最大路网交通流量模型；下层是道路网上的用户均衡分配模型。应用遗传算法进行求解，仿真示例表明该模型和算法是可行的、有效的，可以为城市交通可持续发展的规划和需求管理提供依据。

| Abstract: | A model which is a bi-level optimal problem can calculate the maximum carrying capacity of the zonal road networks in urban with constraint of urban noise environmental capacity is developed.The upper level maximizes the traffic flow subjected to the noise environmental capacity.The lower level assigns the OD traffic on road network with user equilibrium method.Genetic algorithm is applied and a numerical test is used to verify the effectiveness of model and algorithm.The results indicate the model and algorithm are feasible and effective,and the have provided a reference for the urban traffic sustainable development design and management. |
