在对山区高速公路连续下坡路段交通组成、交通事故数据和道路几何线形指标进行分析的基础上,确定了山区高速公路连续下坡路段的典型车型,应用世界道路协会(PIARC)的温升模型对连续下坡路段的长度进行了界定,分析了道路几何线形指标对连续下坡路段交通安全性和驾驶员心生理的影响,并对连续下坡路段的安全保障措施进行了总结和分析。
Based on the analysis of the traffic composition, traffic accident data and geometric line indexes of the continuous downhill section of mountainous expressway, the typical models of the continuous downhill section of the mountainous expressway are determined. By means of the temperature rising model of the World Roads Association (PIARC) The length of downhill section is defined. The influence of road geometry index on traffic safety and driver’s psychology is analyzed. The safeguards of continuous downhill section are summarized and analyzed.
