| Based on the requirements of vehicle-road collaboration technology,this paper designs a road signal light coordination system for vehicle-road collaboration to optimize road traffic efficiency.Firstly,the intersection lane model is designed according to the vehicle-road collaboration technology,and a typical model is used as an example to analyze the collision point of the vehicle through the intersection.After that,according to the different functions that the system needs to achieve and the role between each module,design the road signal light coordination system for vehicle-road coordination,build the hardware architecture of the road signal coordination system,and select the hardware modules such as radar,data acquisition card,data acquisition module and communication module according to the hardware architecture requirements;Then,the control method of road traffic signal based on vehicle-road collaboration technology is designed,the collision of vehicles passing through intersections is analyzed by using speed regulation vehicle traffic strategy,the collision point of vehicles is analyzed by simulating single-lane model and single-vehicle multi-lane model,and the collision point of vehicle passage is calculated by designing algorithms,and the vehicle passes safely and quickly through the intersection by designing vehicle traffic strategies.Finally,the collision point algorithm of the speed-regulated vehicle passage strategy is modeled.The model verification results show that the speed-regulating vehicle traffic strategy is safe and reliable,and the designed algorithm can make the vehicle pass through the intersection safely and efficiently. |
