Research on Integrated Scale Prediction of Freeway and Expressway in Metropolitan Area

Abstract

Freeway and expressway are the main supporters for the long and fast travel demand in metropolitan area, which play the vital roles in urban transportation system, producing huge transport efficiency. In this context, the integration of both in planning and construction is one of the important measures to alleviate the urban traffic problem. Specifically, the following question should be focused on: How to predict the scale of them. In this paper, based on demand analyzing and supply characteristics of freeway and expressway system, a supply-demand balance method for predicting the integrated scale of freeway and expressway was conducted, and the supply-demand balance model was established. Finally, an applied research was carried out as an example in Zhenjiang metropolitan area.
