摘要
为了评价高速公路路段的安全性,提高高速公路的安全运营水平,以交通工程学、计算机科学等理论为指导,在大量实地调查的基础上,应用层次分析法进行高速公路路段安全性影响因素分析,结果表明,驾驶员疲劳驾驶、车辆运行速度、道路纵坡度和车辆间干扰是引起道路交通事故的最主要因素。采用元胞自动机理论方法,构建了高速公路路段安全评估模型,确定了高速公路的安全等级,为高速公路的安全评估提供了一种新的思路。
In order to check the safety of highway section and improve the overall safe level of operation on highway,by a large number of field survey,based on traffic engineering and computer science,AHP is used to analyze the safety of highway section,the results show that the most important factors which result in traffic accident include driver fatigue on driving,vehicle speed,road gradient and vehicle interference.Based on the cellular automata theory,a safety assessment model of highway section is built to determine the level of highway safety.It provides a new way of thinking for safety assessment of highway.
