| 摘 要： | 道路立体交叉远景交通量预测是道路立交规划和设计的重要环节，根据交叉口交通流特性和规划路网的路段交通量，构造了立体交叉远景交通量预测模型。此模型通过迭代计算预测立体交叉口进口和出口之间的转向交通量，同时对模型中参数的计算进行了讨论。通过某一实例对模型进行了验证，结果表明该模型误差较小。

Traffic volume forecasting method at road interchange based on road network planning |
| |
| Abstract: | Traffic volume forecasting at road interchange is a key part of road interchange designing and planning. According to the characteristics of traffic flow at interchange and the volume planning at road network, this paper put forward a new traffic volume forecasting model. The traffic turning volume from entrance to exit could be forecasted, and the calculation of the correlative parameters was discussed with the model. The forecasting model was tested by an example. The result shows that this model is feasible. 4 tabs, 2 figs, 7 refs. |
