城市道路路侧冗余信息对指路标志视认的干扰对行车安全极为不利。设计了不同信息量的城市道路指路标志牌,并与典型的路侧冗余信息组合设置;然后在大量室内模拟试验基础上,利用稳健估计理论与方法,分有目标路名、无目标路名2种情况,对单块指路标志、道路景观标志组合、小汽车标志组合、女明星标志组合、路名(地名)指路标志组合的视认时间、视认反应时间进行了对比研究,得到不同类型路侧冗余信息对指路标志的影响程度。结论:路侧冗余信息影响程度从大到小顺序为路名(地名)标志、女明星广告、小汽车广告、道路景观。其中路名(地名)辅助信息、女明星广告干扰十分显著,在城市交通中应尽量避免;小汽车广告、道路景观干扰较小,可适当设置。
Disturbance of the redundant information of urban roadsides on the visual recognition of road signs is extremely unfavorable to traffic safety. Design urban road signboard with different amount of information and set it in combination with the typical roadside redundant information. Then, based on a large number of indoor simulation tests, using the robust estimation theory and method, Two cases were studied, the contrastive study of the visual recognition time, the visual recognition reaction time of the single road sign, the road landscape sign combination, the car sign combination, the female celebrity sign combination and the road name (place name) Get the different types of roadside redundant information on the impact of road signs. Conclusion: The influence degree of roadside redundant information descending order is road name (place name) sign, female celebrity advertisement, car advertisement, road landscape. Road names (place names) auxiliary information, female stars advertising interference is very significant, in urban traffic should be avoided; car ads, road landscape interference is small, may be set properly.
