Research On The Identification And Prevention Technology Of Black Spots On Mountainous Arterial Highway

Along with the economic development of our country,the traffic pressure on t mountainous trunk highway is increasing,resulting in frequent accidents and seriously affecting the safety of driving.Based on the field investigation and a large number of data collection work,this paper has the important practical significance to carry out Research on the identification and prevention technology of black spots in mountainous arterial highwayFirst,with the help of VBOX,dynamic ECG,radar velocimeter and other instruments,the data of the line parameters,driver’s heart rate and driving speed are collected.The relationship between the line parameters and the speed of the road is studied by mathematical statistics and analysis,and the classification standard of mountainous trunk highway is obtained.The method of comparative analysis is used to analyze the advantages and disadvantages of traditional black spot detection methods.Secondly,By analyzing the time distribution of accidents and the form distribution of accidents on mountainous trunk highway,the impact factors of accidents are analyzed from the aspects of human,vehicle,road,and environment,and the mechanism of accident black spots on mountainous trunk highway is discussed.The grey incidence analysis method and entropy weight method are used to analyze the significant influencing factors of accidents.Thirdly,based on the significant influencing factors of mountainous trunk highway,the relationship between the growth rate of driver’s heart rate,the linear parameters and speed is analyzed,and the safety assessment of mountainous trunk highway based on drivers’ physiological responses was established.By identifying the tension and safety threshold of the growth rate of driver’s heart rate,the method of identifying the black spots on mountainous trunk highway is proposed.Finally,by identifying accident black spots in the project,a deceleration system based on driver’s visual illusion is developed for accident black spots.The application can effectively reduce accidents and improve safety of roads.Carrying out the policy of "safety is first and precaution is crucial" will bring huge social benefit.
