摘　　要：为了提高城市道路指路标志设置的有效性和科学性,根据驾驶人视认特性的实验数据研究其设置方法.利用眼动仪和GPS采集了不同光照条件下驾驶人视认指路标志的特性数据,建立了基于驾驶人视认特性的指路标志设置参数计算模型,并将计算的设置参数与规范值进行了比较.研究发现,驾驶人对指路标志的注视时间随速度和路名数目的增加而增大,且非专业驾驶人的注视时间大于专业驾驶人,顺光条件下的注视时间小于夜间.驾驶人对指路标志的视认距离随速度的增加而减小,顺光条件下的视认距离大于夜间.分别满足专业和非专业驾驶人视认要求的主要设置参数存在显著差异,部分规范值不能满足非专业驾驶人对指路标志准确视认的要求.In order to make the setting of road guide signs more effective and scientific,the setting of road guide signs based on the experimental data of driver＇s recognition was studied in this paper.Driver＇s recognition parameters of road guide signs under different light conditions were collected by eye tracker and GPS（global positioning system）,and a calculation model that defines the main setting parameters of road guide signs based on driver＇s recognition characteristics is established.The calculation results were compared with the existing norms.The research shows that the fixation duration of drivers to road guide signs increases as the speed of the vehicle and the road name number increase,and the fixation duration of novice drivers is longer than professional drivers.In addition the fixation duration under front light is shorter than that at night.The recognition distance of road guide signs decreases as the speed of the vehicle increases,and the recognition distance under front light is larger than that at night.The main setting parameters that meet the recognition requirements of professional drivers and novice drivers are notably different,and some setting parameters of the existing norms cannot meet the recognition requirements of novice drivers.
