摘要
为了减少超车风险,建立较为完善的超车模型,本文对超车危险因素进行分析,形成超车因素风险指标体系。应用系统工程的理论对双车道公路超车危险因素进行分析,建立超车过程风险因素5级多层递阶解释模型结构,通过分析双车道公路超车风险因素之间的结构和层级关系,得出结构模型和解释结构模型图,找出影响双车道公路超车的直接因素、间接因素。研究表明,多层递阶ISM方法能有效的建立双车道超车风险因素辨识结构模型,直观的反映出各个影响因素之间的层级关系,操作简便,实际可行。
In order to reduce the risk of overtaking and establish a relatively perfect overtaking model, this paper analyzes the overtaking risk factors and forms a risk factor index system. Based on the system engineering theory, the overtaking risk factors of two -lane highway are analyzed and a five level hierarchical interpretative structural modeling is formed. By analyzing the structure and hierarchy among risk factors, the structure model and interpretative structural model are obtained and the direct and indirect factors that affect the two lane highway overtaking can be achieved. Research shows that the hierarchical ISM can effectively build a two lane highway overtaking risk factors identification model which can reflect the hierarchy among factors directly. The system has the advanta-ges of easy operating and practicality.
