| In the data analysis based on traffic accidents,road traffic accidents directly caused by drivers account for about 70%.If we consider the human factors in vehicle,road design,construction,maintenance and road environment,there are nearly 90%of accidents and people.Related factors.Drivers’ mistakes in driving are the direct cause of road traffic accidents.Driver errors are caused by many factors,including the driver’s own,traffic management rules and road operating environment,but the driver himself is causing traffic accidents.The root cause.The road traffic environment in China is complicated.Although the number of road traffic accidents is decreasing year by year,the total number of traffic accidents cannot be underestimated.Therefore,research on dangerous driving for driving behavior is of great significance.This article first sorts out 356 passenger car accident cases in the Chinese CIDAS database and describes the characteristics of the accident.The data shows that traffic accidents are closely related to driver behavior,which is manifested in individual characteristics such as driving style,age,and driving age.In addition,traffic accidents have a strong relationship with basic environmental factors.In order to understand the causes of traffic accidents in more detail,we analyzed the mechanism of dangerous driving conditions.Secondly,this article collects individual driver information and environmental information,conducts detailed research on driving behavior characteristics and general patterns,and analyzes the influence of individual driver characteristics and environmental factors on driving behavior.Finally,based on the real traffic accident case of CIDAS,this paper conducts a questionnaire survey of non-professional drivers as a sample,and then the statistics of the CIDAS real traffic accident driving return survey data and accident morphology information,to build a "driving behavior score-performance model-evaluation index" dangerous driving behavior evaluation system three-tier structure.Through the gray clustering theory,the driver’s propensity for accidents is obtained.The results show that drivers aged 18-30 are more likely to have accidents,while drivers aged 6-10 years have the highest tendency to have accidents.Followed by drivers of 4-5 years,general drivers have the highest tendency to cause accidents among the three types of drivers.Based on the summary of driving behavior and traffic safety,this paper expounds the research status and progress of driving behavior and traffic safety based on people,vehicles,roads,environment and traffic management,and prospects the current research on driving behavior and traffic safety.It provides a solid theoretical foundation for the safe and effective control of vehicles,paving the way for research on driving behavior and active safety technology and unmanned technology. |
