TransCAD在道路交通需求预测中的应用——以晋江双龙路项目为例

Application of trans CAD in road traffic demand forecast——Taking jinjiang shuanglong road project as an example

针对道路项目中交通需求预测独有的特点,结合晋江双龙路项目,介绍TransCAD在四阶段预测中的应用。研究表明,得到的预测结果,不仅为双龙路项目的规模论证提供科学依据,OD反推的方法、双约束重力模型也能够为道路设计中同类项目交通需求预测提供一定的借鉴。

According to the unique characteristics of traffic demand forecast of road project,combined with Jinjiang Shuanglong road project,we introduced the application of Trans CAD in the four stage prediction. Research shows that,the results of the prediction,not only to provide the scientific basis for scale argumentation of Jinjiang Shuanglong road project,the method of OD back stepping,double constrained gravity model can also provide some reference for the traffic demand forecasting of the similar project of the design in road.
