Research On Traffic Accident Mechanism Of Expressway Low-Information Intake Sections

Low-information intake sections is part of the expressway, the traffic safety of it can’t be defined bythe existing design standards and evaluation method, and the traffic accident mechanism of it was almostblank. So the research on it has important realistic significance and application value.The paper had started with the demand theory of expressway low-information intake sections’accident mechanism, based on the field survey data and the psychology (Biological psychology,environmental psychology, cognitive science) professional latest theory and had systematically andcomprehensively researched the expressway low-information intake sections’ accident mechanism anddriving behavior by using the method of combining the mathematical statistics, theory fusion and systemanalysis. The paper included the research of expressway low-information intake sections’ features, theanalysisof the typicalsectionsa and researches of Driving environment-behavior relationship and accidentmechanism on the sections and Security measures.The paper had analysed that driving in the environment of less disturbance and lower drivingcomplexity will easily lead to few driving operation and reducing of psychology tension by studyingdrivers’ operation characteristics and feeling feature on expressway low-information intake sections. Andthe paper had studied the influence of drivers’dynamic visual, feeling adaptation, selective attention andperceived defense in expressway low-information intake sections ontheir ingesting, analyzing and dealingwith external environment information and had defined the typical low-information intake sections bystudying the process of drivers’perception road information. By analyzing the expressway typicallow-information intake sections’ accident distribution, accident cause, travelling speed, and so on, the paperhad studied the danger of low-information intake sections and put forward three kinds of hazardousexpressway low-information intake sections.The paper first introduced environmental psychology theory system to study the d traffic safety ofexpressway low-information intake sections. And the paper put forward the influence of the Externalenvironment stimulate on drivers’ Cognitive evaluation, physical sensei, behavior and emotionalexperience and the correlations between them, and had confirmed that awakening is the key factor. Thepaper had studied that expressway low-information intake external environment is easy to cause drivers’low performance, produce cognitive distortion and bad mood based on Environmental psychologytheory. The paper had systematically studied Driving environment-behavior relationship in expresswaylow-information intake sections and had analyzed the cause of speeding and driving fatigue, put forwardDriving environmental stress model and accident mechanism in expressway low-information intakesections, and put forward the traffic security measures to enhance the environmental stimulation and senseilevel in expressway low-information intake sections.
