Research On Typical Potential Dangerous Driving Scenarios

At present,China's road traffic accident casualty rate is still high,the road traffic safety situation is very grim.The driver is the leader of road traffic safety,and many traffic accidents occur because the driver does not perceive and predict the potential danger in the traffic environment,and can not take measures to avoid in advance,leading to the accident.Therefore,to strengthen the driver's perception of risk perception and processing capacity,can effectively predict the potential danger,you can reduce the occurrence of traffic accidents.This article first analyzes the road traffic safety system as a whole,and analyzes the four elements of people,vehicles,roads and environment that make up the system.Mainly on the motor vehicle drivers,non-motor vehicle drivers,road grade,road line type,road quality,road intersection,a variety of weather conditions and night conditions and other elements were analyzed,we can see a lot of traffic accidents are due to Motor vehicle driver caused by illegal.Secondly,the summary of the previous traffic accident classification,through the summary of previous achievements,found a reasonable classification for the driver training,that is,by urban road,township road,mountainous road and highway four kinds of common road classification.The characteristics of the four roads and four kinds of accidents on the road often carried out a detailed analysis of the type of accident.Based on the statistics of traffic accidents in 2011-2015,the influence factors of traffic accidents were analyzed by gray correlation analysis method.The main factors and secondary factors influencing road traffic accidents were obtained,and 26 kinds of scenarios of the scene library,carried out a simple case analysis.One more,using 3DMAX software to create a simple accident scene on the have been designed accident scene,a potentially dangerous point has been set up in the animation.It is convenient to combine with eye tracker to test the difference between the new and old drivers and the effectiveness of the scene.Mainly established the city road,urban road,mountain road and highway road four kinds of scene animation.Finally,the mainly job is to design the eye tracker and scene animation experiment and to collect the driver's eye movement data,mainly fixation,saccade and blink data,as well as the location of the eye and the location of the fixation,and to analyze and filter to obtain valid data.Draw the picture of the fixation and compare the number of fixation about the potentially dangerous points,and get that the number of fixation points for skilled drivers is more than that of the novice driver.A comparative analysis of the gaze time was made,and the skilled driver's gaze was longer than the novice.By contrast,the validity of the scenario design is also verified.
