Research On Driver Behavior Characteristics Under Dynamic And Static Comprehensive Driving Suitability Conditions

A large number of Statistical results of road traffic accidents at home and abroad show that the human factors(i.e.drivers)are the main factors.Resear ch on driving suitability show that traffic accidents caused by human are conc erned not only with driver's physiological and psychological factors,but mostly with dynamic driving suitability index in risky situations.Therefore,research on safety feature of driving behavior under condition of static and dynamic co mprehensive driving suitability,can improve driver's ability of comprehensive evaluation on driving suitability and provide effective theoretical basis for the driver's license exam selection and training.The thesis first summarizes the deficiency of driving suitability theory at home and abroad,it demands that the driver should not only possess basic req uirements of driving skills,but also recognize,judge and execute in time in d aily driving.Based on driving suitability test system and KMRTDS simulation system,the thesis selects valid data of 30 subject driver's dynamic and static driving suitability index data out of 62 subjects to analize drivers' safety beha vior under condition of static and dynamic comprehensive driving suitability.C ombining static and dynamic driving suitability and using entropy method,prin cipal component analysis and cluster analysis combining.data analysis method,the thesis put forward the fusion of static and dynamic driving suitability drivi ng suitability index,and establish dynamic evaluation model of driver safety f eatures under the condition of static and dynamic comprehensive driving suitab ility.The thesis then put clustering analysis on 30 subjects by means of SAS d ata.Results show that the 30 subjects were divided into 5 groups;the thesis c arried on divergence testing analysis on comprehensive driving suitability of di fferent population statistics,results showed that the difference is not significan t with respect to different gender,age and driving experience.Finally,based on the classification of drivers,different categories of subje cts for correlation between sex and comprehensive driving behavior,the results show that the sample size is large enough the case generally there will be si gnificant,so the follow-up study should increase the sample size;the IV class were significantly perceived characteristics and direction the risk of wheel angl e standard deviation and MAX correlation,positive correlation;the II class we re significantly related to MAX risk perception characteristics and longitudinal acceleration,showed a positive correlation;the V subjects perceived risk chara cteristics and the standard deviation of the longitudinal velocity correlation sig nificantly positive correlation;and the ? class the subjects of risk perception characteristics and 5 kinds of risk behavior parameters has no significant corre lation.
