Study On Comprehensive Identification Method Of Driving Tendency

With the rapid development of the economy,the car as the one of the most common and convenient means of transport,is being used by more and more people.Road traffic safety problems are also increasingly prominent.Among influential facts of traffic safety,the internal factor of drivers is one of the key points.Moreover,the vehicle-environment affects the traffic safety simultaneously through people-the driver.According to the view of international and domestic scholars,the driver's physiological and psychological characteristics are closely related with traffic safety.As the basis of psychology factors,physiology factors play important roles in impacting driver's behaviors.The factors that closely related with driver's physiological and psychological characteristics include gender,age,driving experience,personality,driving tendency and so on.And the differences between driver's behavior induced by that of gender,age,driving experience and personality usually can be all attributed to the driver's tendency.The driving tendency is the research object in this paper.According to the driver's psychology test,as well as the research results of traffic psychology and engineering psychology,such as the driver's physiological and psychological features under the exogenous and endogenous environment variables,the analytic study on the driving tendency mechanism is undertaken,different types of drivers corresponding to the driving tendency characteristics are studied,and the theoretical basis are provided for the research on personalized automobile safety driving warning system based on driving tendency identification.The results show that:Firstly,the definition of driving tendency is described,and the affecting factors and performance features of the driving tendency are analyzed,and the classification of driving tendency is showed.Secondly,the driver's driving tendency is measured through designing questionnaire,and the factor analysis of survey results is conducted.Thirdly,the drivers are classified by the psychological questionnaires of driving tendency,then the characteristics of different driving tendency are investigated and analyzed.Fourthly,the evaluation system of the driving tendency is built,then the driver's driving tendency is judged by the use of multi-level fuzzy comprehensive evaluation method and evidence theory.Then based on the driver's psycho-physic characteristic and the fact that the knowledge representation and acquisition could be fused,decision tree was used to study the driver's driving tendency.
