路侧安全改善新理念及应用

The new principle of roadside safety improvement and application

科学设计路侧,采取行之有效的措施改善路侧安全,对减少路侧交通事故,改善道路的安全性,提高交通安全水平具有重要意义。综合考虑了人—车—路系统中的诸多因素,从车行道、车辆以及驾驶员三个方面分析了影响路侧安全的主要因素,并从综合考虑车行道、车辆以及驾驶员的改善方法和防止车辆侧翻、碰撞、降低伤亡率两个不同的角度提出了改善路侧安全的新理念,最后将改善路侧安全的新理念应用于路侧安全改善设计中。

Using scientific designs and valid measure to improve road side safety,it has important meaning towards reducing the roadside traffic accident,improving road safety and raising traffic safety level.According to these purposes,considering many factors in the roadway-vehicle-driver system comprehensively,the paper analyzed the influence factors of the roadside safety on the three aspects of roadway,vehicle and driver.Put forward a new principle of improving the roadside safety from two different angles,one method is to consider roadway,vehicle and driver,the other is to keep the vehicle from sideslip,collision,and to lower dead and injured rate.Finally,this paper applied the new principle of the roadside safety to improve the roadside security.
