摘要
公路指路标志信息需求的增加容易导致驾驶员识别信息量过载与标志版面大型化,使驾驶员无法在安全时间内阅读完标志上的信息,因此,公路指路标志极限信息量研究是确保驾驶安全的重要课题。通过室内仿真实验与真实环境下的实验相验证的办法对标志信息量与驾驶员认知时间的关系进行了研究,并由此确定公路指路标志的极限信息量。
It will likely lead to information overload and the guide signs upsizing, when the traffic information demand on highway guide sign were increasing,and will cause the drivers impossibly red over it in safe time interval. The research subject of ultimate information content on a highway guid sign is a important subject for ensure the safety. The ultimate information content related with road name and the reaction time was studied by using the method of emulational tests indoor and compare with field investigation.The ultimate information content on a highway guid sign was determined.
