| 摘 要： | 在考虑到高速公路上前后车的相对速度对临界安全距离影响的情况下,分析车辆的制动过程,研究不同路况下最大制动减速度的变化,对驾驶员反应时间、制动协调时间和减速度增长时间进行了合理设置,在以上分析的基础上建立高速公路临界安全车距模型,并进行仿真分析。仿真结果表明:本临界安全距离模型更具有合理性。

| Abstract: | After considering the influences of the relative speed of front and back vehicles in highway on the critical safety distance,the braking process is analyzed,the variety of the maximal deceleration in different road situations is studied,and a reasonable assumption for the drivers' response time,coordination time and braking increase time is made.Finally,this paper builds the critical safety distance model to do simulatation.The result from the simulation shows that the critical safety distance from the mode... |
