Research On Road Warning Signs Based On Cognitive Understanding

With the increase of automobile ownership in China,it has brought great influence to road traffic.Traffic congestion and traffic accidents have increased,causing huge losses to the social economy and people's lives and property.As a kind of public environment sign,road traffic signs use graphical symbols and text symbols to transmit various information to drivers and road users.It is also an important safety facility to guide the operation of road traffic.Through the study of related literatures,it is found that warning signs and ban marks are more important to the driver's personal safety than other road traffic signs.They suggest that the driver is potentially dangerous in certain special road sections.However,only when the driver can accurately understand the meaning of the traffic signs,can make more reasonable judgments and make correct driving behaviors,thereby reducing the occurrence of traffic accidents.Therefore,relevant research on the design of road traffic signs will have a positive effect on maintaining traffic order and reducing the loss of life and property caused by traffic accidents.The design of road traffic signs is a crossdisciplinary and interdisciplinary research topic involving design,semiotics,design cognition,and road traffic.Starting from semiotics and design cognition,this paper combines relevant literature research and road traffic reality analysis to propose a research topic of traffic sign cognitive understanding with warning signs as the research object and Pierce semiotic media analysis as the research method.In this study,the subjective evaluation scale of traffic signs was designed by using the ergonomics symbolic evaluation theory.Through the understanding of the driver's warning signs,they obtained their understanding scores for each warning sign and established the driver's logo understanding and The relationship between various factors of ergonomics.Then combined with Pierce's semiotic theory to analyze the driver's cognitive process of each warning sign,and get the five reasons why the warning sign is caused by the media factor.Finally,combined with the design theory,the design strategy to promote the cognitive understanding of warning signs is proposed,and the design strategy is verified with the design case.The results are in line with expectations.
