中文摘要
道路交通系统是由人、车、路、环境四要素组成的一个复杂大系统。驾驶人作为该系统中唯一一个拥有思维,能自我反馈修正个体行为的复杂能动主体,是系统中的核心要素,在控制和协调交通系统方面起着主导作用。驾驶人对注意的处理过程是经其感知和判断等心理过程作用的结果。我们根据认知心理学原理,从驾驶人感知觉、意识、记忆等特征出发,通过驾驶人的适应性分析,得出驾驶人的注意处理过程的概念模型。
虚拟现实(Virtual Reality)是近年来出现的高新技术,利用虚拟现实技术可以使操作者能够真正进入一个由计算机生成的交互式三维虚拟环境中,与之产生互动,进行交流。道路行驶过程中影响驾驶人注意的因素主要包括行车环境、遮挡、炫光以及驾驶人自身因素等。本试验是通过设计山区隧道和山区转弯两路段的交通标志试验场景对驾驶人注意的影响因素进行系统问卷调查,分析结果表明用该仿真试验来研究驾驶人对交通标志注意这种方法是可行的。

Abstract
Road traffic system is made up of people, vehicles, roads, environment is plicated large posed of four elements. Driver as a unique thinking mode of the system, can be self feedback correction individual behavior plex dynamic main body, is the core of the system elements, in the control and coordinated transportation system plays a leading role. Driving people to pay attention to the process is with the mental processes of perception and judgment of the results. We according to the principle of cognitive psychology, from the drivers sense of perception, consciousness, memory, and other characteristics, by means of driver's adaptability analysis, concluded that drivers pay attention to the concept of process model.
Virtual Reality (Virtual Reality) is a high and new technology in recent years, the use of Virtual Reality technology can make the operator can enter a real interactive 3 d Virtual environment generated puter, and the resulting interaction, munication. Affect drivers pay attention to in the process of road factors mainly includes the driving environment, shade, dazzle light and driver itself factors, etc. This test is designed by two sections of the tunnel and turn in the mountainous area traffic signs for drivers to pay attention to the influence factors of test scenarios system questionnaire, analysis results show that the simulation test is used to study drivers on traffic sign note this method is feasible.
