Study Of Highway Dangerous Driving Behavior Under Ice And Snow Pavement

Heilongjiang province is situated in the north of China, with long ice and snow time,From2008to2011, highway mileage of Heilongjiang province has seen massive growth.at the same time, the automobile of heilongjiang province has a big increase, the traffic accident rate is rising year by year, has bring deep influences to economy, politics and every aspect of social life of heilongjiang province. Under the condition of ice and snow road, Easily lead to accidents, how to improve the safety performance of highway snow and ice conditions, has the very vital significance.This paper analyzes the snow conditions on the highway road conditions, visibility environment, vehicle type, and vehicle characteristics to traffic on highway traffic safety impact. Select the vehicle speed, vehicle acceleration, distance, vehicle parameters from the four left lane as the front line distance characteristic factor, constructed highway dangerous driving behavior identification model snow conditions based on hidden Markov model, identify speeding driving the car in less, illegal overtaking lane pressure other four dangerous driving behavior. Finally, these four dangerous driving behaviors appropriate safeguards developed and established by the video surveillance subsystem, dangerous driving behavior identification subsystem, information dissemination subsystem three subsystems dangerous driving behavior monitoring system.This paper was first used in the field of speech recognition Hidden Markov model to dangerous driving behavior of the vehicle identification field, the identification model is embedded into the current highway monitoring system to establish real-time monitoring system for dangerous driving behavior.Research shows that the risk of driving behavior identification based on hidden Markov model can accurately identify the model of dangerous driving behavior under conditions of highway snow and ice, but also for the proposed improvement measures to enhance highway safety under snow and ice conditions makes certain contribution.
