山区高速公路事故多发路段事故原因分析研究

Analysis and Research on Reasons of Accidents at Blackspots on Expressways in Mountainous Area

对某高速公路事故多发段的事故数据进行分析,结合道路线形参数及运行速度等多种因素,指出驾驶人员的反应、车辆组成结构及道路线形、超高、摩擦系数、视距等外部因素的综合作用是山区高速公路事故多发的根本原因。

This paper analyzes accident data at blackspots of some expressway and points out that the synthetic action of external factors such as the reaction of drivers, composition of vehicles, road alignment, over-height, frictional coefficient and range of visibility, etc. is the reason for frequent occuranee of blackspots on expressways in mountainous area.
