高速公路纵面设计微观事故预测模型研究

Study on Microcosmic Accident-predict Model Focused on Vertical Design of Expressway

介绍以道路设计要素的安全机理分析为基础 ,以统计分析为研究手段 ,针对高速公路纵面设计要素以及相关的要素组合、衔接方式所建立的事故预测模型。该模型体系可为公路安全设计。

This paper is focused on the study of accident predict model used for vertical design of expressway. On the basis of fundamental of traffic safety, this model stresses and explores the relationship between traffic safety and specific vertical alignment with joint and combination style.
