Study On Characteristics Of Driving And Its Countermeasures To Road Safety

Quantities of statistics show that more than 70 percent of road accidents are directly related with drivers and their driving characteristics, which are generally caused by driver's faults in perception, judgment and operation. This paper analyzes the driving characteristics, driver's own perception and judgment as well as operating characteristics and their influence on the road safety and then, proposes the feasible driver's management countermeasures, all of which have been regarded as an effective method concerned with propriety to reduce road accidents and enhance driving safety from existing serious situation.Based on the former research results, this paper investigates the issues of driving fatigue and comprehensive evaluation model based on driving characteristics, and analyzes the driving characteristics and their relevance with the road accidents by using the source materials analysis, applying the methods of level analysis theory and fuzzy theory, adopting means of document microscopic analysis, questionnaire and experimental test, etc. Meanwhile, under the goal of proposing countermeasures of preventing the traffic accidents by means of improving the driving characteristics, this paper systematically and thoroughly develop the research work.Based on the analysis of driver's perception, judgment, operating characteristics and affecting factors, a accident causes model is constructed to describe the driver'own mistake characteristics and its relation with the road accidents from microscopic angle, where weight of key affecting factors are determined by improved AHP method and its affecting level is quantitatively computered so as to provide a scientific basis for the prevention of driver accidents and the provision of operation measures.The paper studies the fatigue influence on the driver's perception, judgment and operating characteristics. With experimental data on driver's fatigue, investigation has been carried out to analyze the driver's perception, judgment and operating characteristics under different fatigue degree, the paper confirms the relation between fatigue degree and evaluation indicators of driver's characteristics. It also studies changing rules of drivers'evaluatation standards after testing the indicator under different continuous driving time and establishes the relational model between continuous driving time and each evaluation after testing the indicator. Propose the recommended value of continuous driving time based on the driver's driving characteristics. The findings provide the reference basis for the related departments to constitute or revise the rules of limited driving time.Based on establishing the appraisal indicator system of driving characteristics, the paper investigates the driver's perception, judgment and operating characteristics according to experimental psychology. By adopting the test methods and comparison analysis, testing and analyzing the characteristics of certain quantity of drivers disparate in age and sex, the paper determines single item evaluation of the driving characteristics after testing the indicator threshold value; Based on fuzzy and accumulating analysis, the paper introduces the synthesis appraisal classification of driving characteristics, evaluating the driver's perception, judgment and operating characteristics comprehensively. The result indicates that the introduced classification mode and real accidents are in good uniformity, which provides the theory basis for driver's examination and training.Through the in-depth investigation into of driver's characteristics and road traffic safety, the paper proposes the practical feasible countermeasures to prevent road accident for the improvement of driver's perception, judgment and operating characteristics. From the aspects of improving the driver's own psychology adjustment ability, strengthening the driver's psychological training, raising the driver 's occupational ethic standards and enhancing safe consciousness, the paper proposes the countermeasures to control driver's own mistake characteristics and preventing the driver's accidents; Aiming at developing driving compatibility examination, strengthening driver perception, judgment and operating ability training ,etc, the paper also put forward safety countermeasures for improving the driving characteristics; In order to prevent driving fatigue, it proposes the suggestions of longest continuous driving time and the midway relaxation time for drivers, driver's self-control and adjustment measures. The prevention countermeasures for the driving characteristics in road accidents have practical significance for the reduction and prevention of accidents caused by the driver's own mistakes behavior. The research results of this paper will further enrich the road safety research theory, provide the technical support for the analysis of driver's mistakes behavior accidents, and offer the reference for management, training and the examination of the driver. Significantly, it will instruct the driver management, and also provide a safe, healthy and comfortable traffic environment of freeway.
