摘　　要：已有部分研究分析了智能网联车辆与可变限速控制技术结合的安全效果,但缺乏基于驾驶行为特效的对比分析。文章研究了驾驶行为中的三个重要特性指标,即最小限速变化值、反应距离以及不遵章比例,通过建立的微观仿真平台进行了大量仿真分析,生成了微观车辆轨迹数据,并基于轨迹数据分析了智能网联车辆如何改进三种驾驶特性从而提高可变限速控制技术对高速公路安全改善的影响。文章的研究结果为高速公路在智能网联车辆环境下的安全改善提供了参考意义。Some studies have analyzed the safety effect of the combination of intelligent networked vehicles and variable speed limit control technology,but there is a lack of comparative analysis based on the special effects of driving behavior.This paper studies three important characteristic indexes in driving behavior,that is,minimum speed limit change value,reaction distance and non-compliance ratio.Through the micro simulation platform established,a large number of simulation analyses are carried out,and micro vehicle trajectory data are generated.Based on the trajectory data,it analyzes how intelligent networked vehicles improve three driving characteristics to improve the impact of variable speed limit control technology on highway safety improvement.The research results of this paper provide a reference for the safety improvement of expressway in the intelligent network connected vehicle environment.
