基于驾驶行为的夜间山区作业路段安全距离研究

山区公路养护作业多数边通车边作业,为了减少养护作业对道路交通的影响,作业工作常常在夜间进行。为了提高夜间道路交通的安全性,以夜间作业区环境影响驾驶员视觉特性理论分析为基础,应用眼动仪等科学仪器,实地采集驾驶员夜间行车速度、视距和驾驶员的心生理反应等数据,分析夜间驾驶员明适应时间与车速的相互关系,不同年龄驾驶员的暗适应时间的变化规律,得到了速度与安全距离的关系模型,最终确定了基于“黑洞效应”的夜间安全行驶距离值,为解决夜间交通安全事故多发提出来一种思路。

Study on Safety Distance of Night Mountain Operation Area Based on Driving Behavior

Mountain road maintenance operations most of the opening-side operations,in order to reduce the impact of maintenance operations on road traffic, work operations are often carried out at night.In order to improve the safety of road traffic at night,based on the theoretical analysis of the driver"s visual characteristics of the environmental impact night work area,eye tracker and other scientific instruments are applied.Data such as driver"s driving speed at night, line-of-sight and driver"s heart physiology responses were collected.The author analyzes the relationship between driver"s adaptation time and vehicle speed at night, the law of driver"s dark adaptation time at different ages.The relationship model between speed and safety distance is obtained.In the end, this paper determined the nighttime safe driving distance based on "black hole effect".A way of thinking is provided in order to solve the phenomenon of frequent traffic accidents at night.
