With the rapid development of economy and urbanization process,the number of vehicle ownership and driver are rapid increased,but come along with traffic accidents increasing and the huge loss of people’s life and property.As we all know,the driver is the dominant of the road traffic system,and a large number of statistical data and research also show that more than 70%of road traffic accidents are directly related to the driver.The occurrence of traffic accidents is usually caused by the driver’s selective attention and improper handling to the traffic risk information.Therefore,studying on the driver’s selective attention behavior of risk traffic information,can help more indepth understanding of traffic accidents caused by the driver,and very good help analyze the sensing properties of the driver of traffic risk information,and the drivers’education and training,and also have very strong practical significance for improve drivers’safety awareness and prevention of traffic accidents.This thesis is launched based on the above situation.First,have a review of the relevant literature at domestic and abroad,analyzes the factors and research methods of the driver’s selective attention,explore the mechanism of the drivers’ selective attention,and confirmed the methods of the present subject.Secondly,using the collection of tachograph video,classification and grading indication information of the risk traffic information.Select five typical indication risk information video,established indication risk information database.And using the analytic hierarchy process to determine the factors and weight coefficient that affect the indication risk information.Thirdly,30 drivers are organized to carry out the desktop experiments,obtained the driver’s reaction time of the indication risk information and the location that the drivers’click on the screen;VSDesign is applied to design the three-dimensional virtual landscapes,using the KMRTDS driving simulation system developed in our laboratory to carry out the simulation experiment under different kind of indication risk information,collect the drivers’ braking-reaction time and steering response time under different kind of indication risk information.The result show that:the ability of drivers’ selective attention is closely related to driving experience,as the driving experience increased.that means driving experience and reaction time are negative correlation,as driving experience increased,reaction time will be reduced,the score will be increased,the selective attention will be stronger;driving experience and braking-reaction time are negative correlation,with the driving experience increased the braking reaction time is shortened;the kind of indication risk information affect the drivers’ selective attention.old and new drivers’ reaction time of indication risk information are reduced by vehicle-vehicle,vehicle-non-motor vehicle and vehicle-pedestrian order;steering response time is also verified by comprehensive weight coefficient vehicles-motor vehicles,motor vehicle-non-motor vehicles and motor vehicle-pedestrian order;steering response time also verified this point.
