高速公路路面抗滑力与交通事故的模糊分析

Fuzzy Analysis of the Relationship Between Accident and Skid Resistance of Pavement on Motorways

根据对我国 7条高速公路在两年时间内的事故与抗滑力调查 ,用模糊分析的方法对所取得的数据进行了分析 ,得出了高速公路上事故与路面抗滑力关系不明显的结论。这说明在高速公路上尽管行车速度高 ,但行车条件好 ,纵、横向干扰少 ,需要频繁刹车或紧急刹车的情况少 。

This paper reaches a conclusion that the relationship between accident and skid resistance of pavement on motorway is not clear according to the fuzzy analysis of the two year's data on seven motorways in China. This indicates that the friction demands on motorways is lower than that on common highways, although the traveling speed on motorway is much higher than that on common highways. This accounts for the good traveling condition on motorways such as high standard alignment and less longitudinal and lateral interference.
