Abstract

The safety evaluation in the stage of acceptance inspection is the last safety inspection before highway operation, which is of great practical significance to minimize the traffic safety risk during the operation period. Collector-distributed first-grade highway mainly plays the role of collecting and evacuating traffic. It has the characteristics of many intersections and mixed traffic. Its traffic characteristics are complex, so traffic accidents occur frequently. Taking the safety evaluation of Leicheng connecting line of Donglei highway as an example, this paper analyzes and evaluates the main factors affecting the operation traffic safety of the collector-distributed first-grade highway, such as sight distance, clearance of highway, median divider opening, piers and abutments of upper-span bridges, speed limit scheme, and puts forward corresponding improvement suggestions, in order to reduce the accident rate during highway operation and ensure the safety and smoothness of highway traffic.
