中文摘要： 近年来我国高速公路长大隧道群段交通事故数居高不下，且严重性强，已成为严峻社会问题，其中驾驶员视觉疲劳是主要诱发因素之一。高速公路长大隧道群驾驶环境封闭单调，频繁进出隧道致使驾驶员视觉明暗适应困难，产生"驾驶疲劳"，从而增加交通事故潜在风险，但目前我国尚缺乏对整个隧道群段驾驶员视觉疲劳问题的系统理论研究，相关管理政策措施无法跟进。本项目拟充分借鉴已有成果，通过现场测试，采集驾驶员眼动等指标参数，分析其变化规律，甄别其视觉"兴奋点"、"疲劳点"；结合指标测试结果，引入视觉疲劳和视觉疲劳指数的概念，确定度量标准，分析驾驶员视觉疲劳从形成到累积的演化规律，并研究其与驾驶绩效、照度、车速的关系；根据驾驶员视觉"疲劳点"在长大隧道内的分布区间，设置灯光刺激，提高视觉兴奋性，并模拟测试实用效果。项目组拥有驾驶模拟系统等实验平台和工作条件，在视觉特性、驾驶行为等方面具有研究基础，具备完成项目研究的条件。

英文摘要： Even though the number of dead and wounded in the long freeway tunnel involved traffic accidents has been decreased over the previous decade, the statistics are still alarming and it has already become a serious social problem in China. Obviously, a great amount of factors contribute to the accidents at these locations and driver's vision fatigue plays an decisive role in causing crashes and facilities. Due to the lonely and boring driving environment in long freeway tunnel group, driver's vision faces significant diffuculty in adapting the unexpected lighting change while entering and exiting the tunnel frequently, which may result in a "visual fatigue" and even lead to accidents. However, the all-around understanding of vision fatigue has still not been realized and thus the effective countermeasures could not be pursued. Therefore, this project analyzes the reported findings and collects the eye movement through experiment so as to judge their variation law with time and identify the excitation and fatigue locations of vision. The definitions of vision fatigue as well as vision fatigue index are determined and then it intends to fully reveal the aggravation process of vision fatigue. Moreover, the effects of vision fatigue on driving performance, pavement illumination and speed are also checked through data m
