Jiyang Bei-bei, DU Yu-chuan, Sun Lijun

Abstract

The volume,density and speed of space area were defined over again based on the conception of equivalent capacity and the formulas were put forward.Making use of collected traffic flow information of urban expressway, the traffic flow characteristics of urban expressway in Shanghai were analyzed based on the essential traffic flow parameters of space area,after defining the time interval and choosing appropriate expressway sections.Then the operation situation of expressway was obtained and base models based on three basic traffic flow parameters were set up.
