| 摘 要： | 为了建立服务于交通控制的路网宏观交通状态判断模型,首先提出了路网宏观交通状态参数的选取原则,确定了路网宏观交通状态参数;然后运用二流理论推导出路网宏观交通状态参数之间的函数关系,建立了路网宏观交通状态判断模型,在此基础上提出了最佳路网容量的计算方法;最后利用最小二乘法对模型参数进行标定.利用VISSIM仿真软件模拟路网...

| Abstract: | In order to develop a macroscopic flow model of urban network conditions suitable for the traffic control,the criteria for choosing macroscopic traffic variables are proposed,and then the macroscopic traffic variables are determined.The relationships among the traffic variables are derived by applying the two-fluid theory.Therefore,the macroscopic traffic condition model of urban networks is developed,and the calculation method of the optimal network capacity is presented based on this model.The model param... |
