人机系统理论在交通标志有效性分析中的应用

Application of Man-machine System Theory in Validity Analysis of Traffic Sign

针对当前交通标志存在的问题,从人机工程学角度,介绍交通标志与驾驶员、车辆、道路环境构成的人机系统各要素内容;运用人机工程学图示模拟和感觉评价两种方法,对交通标志所处人机系统进行阐述,分析各要素特点及相互关系;结合问卷调查结果,指出交通标志在设计与设置过程中应注意的人机因素。研究成果可为提高交通标志设计、设置的有效性,改善交通安全状况提供理论依据。

In allusion to the present existing problems of traffic sign, each factor of man-machine system consisting of traffic sign, driver, vehicle, road and environment is introduced from the man-machine ergonomics view, the man-machine system of traffic sign is expatiated on and the characters and correlations of every factor are analyzed using man-machine engineering diagrammatic simulation and feeling evaluation, the man-machine factors deserving notice during the process of traffic sign design and setting are pointed out combining with questionnaire results. The research fruits can provide theoretical foundation for heightening the validity of traffic design and setting, as well as improving the traffic safety status.
