Study On The Typical Traveling Track Features And Driving Behavior Mode In Mountainous Highway

With the rapid development of reform and opening up, the total mileage of highway and the car ownership has increased a lot, traffic construction made remarkable achievements. Meanwhile, the traffic accidents has been the biggest source of production safety accidents in China, The death toll accounts for the total number of various types of production safety accidents is increasing year by year. According To Statistics, the death toll of traffic accident is 3.4 million in 2014, and the mortality per thousand vehicles is 2.22. The speed of the vehicle has been used as the main research direction in the field of traffic safety, and its correlational research has also made some achievements. But it’s not enough to just consider speed factor. In the road curved section with unreasonable linear, because of the drivers tend to choose more comfortable path, Trajectory deviation appeared seriously. The statistics shows that the accidents always happened with misfit between the trajectory and the road linear. The study on the traveling track features is significant to analysis of the causes of traffic accidents and security governance in the curve.To investigate the influence mechanism of trajectory formation by the factors in the road traffic system, based on the study and research of domestic and foreign material, by means of experimental study, facing curved road section of secondary level or below, studying on driving tack on curved section, this paper mainly analyzed the features and change rules of driving tack with the change of road conditions and driver types. Next, the author cluster analyzed the experimental data, defined each driving behavior mode, and discussed corresponding behavioral motive. At last, this paper proposed and established the pedigree of driving behavior in the Low grade highway in mountain area based on the traveling track.This paper designed a new experimental method used to collection the track data in the continuous road, defined the conception of trajectory drift rate, which can provide some thoughts to the next work. The study on traveling track features in the different road conditions found that the most important factors which influence the trajectory is curve radius, corner, length, and driving direction. The result of analysis on the change rule of trajectory can provide effective basis to linear reconstruction in curve, formulate speed limit values, accident prediction, setting up traffic safety facilities, and highway traffic management. In the research on different driving behavior mode, the author came up with a stage analysis method, which means the vehicle cornering process is divided into several stages, to discuss all of track type at each stage. The pedigree of driving behavior building at last can enrich the research field of driving behavior. Besides, it can provide reference to complete the driver model.
