Research on the Traffic Improvement Measures for Large Intersections

Abstract

The rate of accident at large intersections is often much higher than that at regular intersections. Besides, the traffic access efficiency of irregular intersections is often much lower. Thus, it is very important to study traffic improvement measures to improve the traffic safety level as well as the traffic access efficiency of large intersections. To improve the increasingly prominent contradiction between supply and demand in large intersections as well as to reduce the number of traffic accidents, the outskirts of large intersections traffic design optimization is developed. At last, some of these methods are applied in an actual intersection to provide some reference for traffic designers
