Research On Intersection Optimization Control Method In Cooperative Vehicle Infrastructure System Environment

With the continuous development of vehicle-road collaboration technology,vehicle network has become a new development direction of China’s road traffic soon,and congestion problem in the new environment how to improve has become a new research focus.Intersection is the core of the congestion,collaborative environment is in the road,the smooth passage of the vehicle is still depends on the reasonable distribution of the resources of time and space,so this article in order to improve the car road coordination under the condition of intersection traffic efficiency as the goal,by studying the new theory to realize the reasonable distribution of the resources of time and space optimization intersection,namely under the condition of collaborative research car road intersection optimization control method,the specific work is as follows:(1)Aiming at the shortcoming of the traditional intersection signal control,the car road coordinated system development present situation,safety,efficiency control model was developed based on the gap theory,studies the optimization control method,intersection saturation clearance is given under the condition of optimal speed calculation method,the optimal speed under the conflict of track prediction method and the saturated clearance under the speed adjustment method,and applies MATLAB-efficiency model for the safety of the paper puts forward the simulation verification.(2)Optimization control based on the theory of the gap in the intersection,based on the fusion of collaborative environment is car road intelligent made vehicles(CAV)characteristics,puts forward the clearance in cooperation under the condition of the vehicle road intersection control method,namely gap control method based on fixed driveway under the condition of intersection and parallel gap control based on variable lane under the condition of intersection method.(3)Vehicles made in the future and not made human under the condition of motorized vehicles(HPV),mix of gap junction coupling CAV/HPV signal coordination control method,study the theory of signal control and clearance of thecoupling way,and gives the against HPV gap selection and signal control mode,improve the efficiency of vehicles in the intersection of peers,for human signal control motorised CAV/HPV is proposed.
