Study On The Way How Color Effects Driver's Space Distance Identification Under Dynamic Environment

Road traffic system is a dynamic system being composed of person,automobile and road, The driver's dynamic visual character is a factor which is mostly relative to traffic accidents. To study for driver's dynamic space distance identification rule will help us to set traffic sign and safety establishment scientifically, ulteriorly, it is important for us to prevent and control traffic accident.This paper designs a experiment concerning to space distance identification for driver, based on analysis of driver's dynamic visual character and color visual character.This experiment explores the rule between automobile speed and space distance identification in different barrier colour on day and night. Besides it,we study the rule of space distance identification in different barrier colour according to different illumination.In the whole experiment,we emphasize that how color effects driver's space distance identification under different environment through change the barrier color. Based on the analysis of experiment data,two mathematic models are founded,one is that the modle between speed and space distance identification in different barrier colour on day and night,and the other one is that the modle between illumination and space distance identification in different barrier colour in dusk, Based on the contrast of driver's identification distance in different barrier colour, we summarize the rule of space distance identification according to the contrast of colour in different environment.
