Large Trucks Long-term On Illegal Lane Discriminant Model Research

At present, large trucks traveling occupancy the illegal lane of highway for a long-term phenomenon of the increasing number, planted safety problems and the impact for the highway traffic on the highway, Due to the upward trend year by year of large trucks traveling on illegal lane caused so many traffic accidents and huge losses,at home and abroad has no specialized detection of violations of big trucks occupancy the highway for long-term illegal lane, there are so many rules which are focused on remediation, public education and the provision based management approach, to the present has not yet received a substantive effect.So this thesis has analyzed and summarized the current domestic and abroad detection techniques applied to large trucks, analyzes the advantages and disadvantages of the various detection techniques,we choose video detection technology,for,ease of installation, inexpensive,many mature video recognition technology does not require human participation, identify the correct rate,so we choose video detection technology in this thesis.Research techniques and methods based on correlation detection under the highway environment of large trucks traveling on illegal lane.Based on the video detection technology, traffic safety distance, calculate the actual movement distance of the camera imaging principle, that "change lanes based security vehicle movement dynamic estimation illegal lane discriminant model", this model is divided into four typical violations, discrimination model one; adjacent lane without cars;discrimination model two:adjacent lane has a large truck in front of the big truck,discrimination model three:adjacent lane has a large truck behind the big truck;discriminant model Four:adjacent lane has trucks behind and in front of the big truck. Large trucks’safe distance,the speed lane change and security as the main parameter to change lanes to study the current situation to driving a large truck to discuss large truck safety program change lanes, and finally the actual driving distance determination according to whether they are big trucks Long-term illegal lane road, and gives the settings and parameters determining the value of illegal lane impact models,and the model algorithm implemented in the specific detection system.Experiments show that the discriminant model can accurately determine whether the big truck long-term illegal lane driving, and driving on illegal lane and determines the type of model, and determine the correct rate over 80%, to achieve a better experimental results, our efforts can provide high-speed illegal lane highway with large trucks to provide strong evidence to support data, reduce the long-term illegal lane and driving large trucks and cause accidents.
