摘要隧道路段作为交通的咽喉，不仅事故多发，而且隧道内发生交通事故后处理困难，极易造成群死群伤。隧道进出口亮度的急剧变化，造成驾驶员明暗适应困难, 是形成隧道进出口事故黑点的重要原因。因此，研究隧道路段驾驶员的明暗适应特性及视觉安全保障技术对提高隧道路段的安全性具有非常重要的意义。30084

本文在通过设计隧道路段驾驶员明暗适应实验的基础上，通过D-Lab驾驶行为分析系统记录了驾驶员在各个隧道行驶过程中的眼动、心生理行为等参数，并主要以心率和瞳孔直径作为评价指标，分析了驾驶员在各个路段行驶过程中的明暗适应性变化特征。再运用数理统计、回归分析等相关数学方法研究了驾驶员的明暗适应性时间变化规律，构建出了驾驶员明暗适应性数学模型。为今后在隧道方面的设计和驾驶员自身在隧道内的安全行车提供更加合理与安全的方案。

Title The study of light and dark adaptation time for the
drivers in the urban tunnels.
Abstract
As the throat of the traffic, the tunnel section, not only accident-prone, and the traffic accidents which happen in tunnel post-processing difficult, easy to cause group die group of injury. Tunnel import and export of the brightness of the dramatic changes, causing the pilot light and shade to adapt to difficult, is the important reason of tunnel import and export of accident black spots. Therefore, research on tunnel sections of the pilot to adapt to the characteristics of light and shade and visual security technology to improve the safety of the tunnel sections has very important significance.
This article through the design of tunnel section of the driver to adapt to the experiment on the basis of light and shade, through the D-Lab system records the driver driving behavior analysis in each eye, the heart is in the process of tunnel driving parameters, such as physical activity, and mainly in heart rate and pupil diameter as evaluation index, analyzes the driver in each section of the adaptive changes of light and shade in the process of driving. Again using the mathematical statistics, regression analysis and other related mathematical method to study the driver's time variation law of light and dark adaptation, build up the mathematical model pilot light and dark adaptation. For the future in the field of tunnel design and the driver itself in the safety of the tunnel driving provide more reasonable and safe solution.
