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仿真软件模拟路网宏观交通状态演化过程,将模型确定的交通状态参数关系与仿真获得的状态参数关系进行对比分析.结果表明该模型能够较准确地判断路网宏观交通状态,且模型参数易于标定,便于实际工程应用.
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 parameters are calibrated by the least squares method. The evolution process of traffic conditions is simulated by VISSIM and the relationships among variables determined by the calibrated model are compared with those from simulation. The results show that the macroscopic traffic conditions of urban networks can be accurately quantified by the calibrated model. The model parameters are easily estimated, so the proposed model can be applied in practice.
