Description

Technical Field

[0001] The present invention relates to the technical field of vehicle management, and in particular to a method for managing vehicle speed at a traffic intersection in a vehicle networking mode. Background Art

[0002] Nowadays, with the continuous improvement of people's living standards, people's desire for comfortable transportation has become stronger and stronger, and the demand for private cars has become higher and higher. Private car commuting has become the first choice for most office workers, but the traffic problems brought about by this have also increased. The simultaneous appearance of large-scale vehicles has caused road traffic congestion, frequent accidents, and difficulty in parking. These problems have shown an increasing trend year by year, and easy travel has turned into difficult travel. What is even more regrettable is that the number of deaths caused by traffic accidents each year has also increased year by year.

[0003] How to improve drivers' traffic safety awareness has become an urgent issue, and traffic intersections are prone to traffic accidents. If the speed of vehicles passing through traffic intersections is controlled, the probability of traffic accidents can be greatly reduced. With the development of technology and policies, vehicles will be fully connected in the future. However, the society currently lacks a method to effectively manage networked vehicles through big data vehicle networking. Now there is an urgent need for a method to use a networked system to manage the speed of vehicles not far from traffic intersections. Summary of the invention

[0004] The purpose of the present invention is to overcome at least one of the shortcomings of the above-mentioned prior art, reduce the current situation of frequent traffic accidents at traffic intersections, improve road traffic safety, and provide a vehicle speed management method at traffic intersections in a vehicle networking mode.

[0005] In order to solve the above technical problems, the technical solution to achieve the purpose of the present invention is:

[0006] A vehicle speed management method for a traffic intersection in a vehicle networking mode is applied to a networked vehicle management system and is mainly used to perform dynamic speed monitoring and management of vehicles at a traffic intersection. The vehicle speed management method includes:

[0007] Collect driving data of moving vehicles: vehicle spacing, number of vehicles;

[0008] Networked backend control center;

[0009] Terminal vehicle.

[0010] Furthermore, in the vehicle speed management method at a traffic intersection under the vehicle networking mode, the networking background control center is connected to the device for collecting driving vehicle data, and is used to receive data collected by the device for collecting driving vehicle data, so as to perform data analysis and calculation;

[0011] Furthermore, in the vehicle speed management method at a traffic intersection under the vehicle networking mode, the networking background control center collects the data of the traveling vehicles transmitted by the traveling vehicles: the distance between traveling vehicles and the number of traveling vehicles, and calculates the maximum speed allowed for the road section based on the distance between vehicles and the number of vehicles according to a preset algorithm.

[0012] Furthermore, in the vehicle speed management method for traffic intersections in the vehicle networking mode, the networking background control center has a preset algorithm formula:

[0013]

[0014] Among them, v represents the maximum allowable speed of the road section, n represents the vehicle number parameter, A represents the moving vehicles, m represents the vehicle spacing parameter, H represents the vehicle spacing, p represents the road distance parameter, and S represents the distance from the traffic intersection.

[0015] Furthermore, in the method for managing vehicle speed at traffic intersections under the Internet of Vehicles mode, the algorithm parameters n, m, and p of the networking background control center are determined by multiple comprehensive factors such as the road grade and the number of lanes in the city where the "method for managing vehicle speed at traffic intersections under the Internet of Vehicles mode" of the present invention is used.

[0016] Furthermore, in the vehicle speed management method at a traffic intersection under the Internet of Vehicles mode, the Internet-connected background control center is connected to a speed meter, and the speed meter is installed several meters before the traffic intersection. The distance between the speed meter installation location and the traffic intersection is determined by the local traffic law enforcement department.

[0017] Furthermore, in the method for managing vehicle speed at traffic intersections under the Internet of Vehicles mode, a speed meter tests the speed of passing vehicles and sends the test results to a networked backend control center via a networked system. After the networked backend control center screens the speeds of the measured vehicles, a speeding warning is sent to the vehicles that are about to exceed the speed limit.

[0018] Furthermore, in the method for managing vehicle speed at traffic intersections in the vehicle networking mode, the terminal vehicle is connected to the networking background control center and receives messages sent from the networking background control center.

[0019] Furthermore, in the method for managing vehicle speed at traffic intersections in the Internet of Vehicles mode, when a vehicle traveling on a road section receives a warning text message from the Internet-connected background control center, the vehicle learns that it has exceeded the maximum allowable speed. At this time, the driver begins to slow down until it reaches a safe speed, thereby allowing the vehicle to safely pass through the traffic intersection.

[0020] Furthermore, in the method for managing vehicle speed at traffic intersections under the Internet of Vehicles mode, the terminal vehicle identity information is obtained through the urban traffic vehicle management service system, and the driver, model and other information of the specific vehicle are obtained through the traffic vehicle management service system where the vehicle is registered.

[0021] The present invention also provides a vehicle speed management system for a traffic intersection in a vehicle networking mode, comprising:

[0022] A device for collecting driving data of moving vehicles, used to collect the distance between vehicles and the number of vehicles, collect and send them to the networked backend control center;

[0023] The networked backend control center is used to receive driving data, process and calculate the maximum permissible speed according to preset arithmetic, receive the speed of vehicles on the road measured by the speedometer, process the vehicle speed data, and screen out speeding vehicles to send warning information;

[0024] Terminal networked vehicles are used to receive speeding warning information.

[0028] 3. The vehicle speed management method for traffic intersections in the vehicle networking mode provided by the present invention uses informatization and networking of vehicle information throughout the process, and the steps are simple;

[0052] A section of XX city was randomly selected, 1000m before the four-lane crossroad of the main road in the city. The speed meter was placed 800m away from the traffic intersection. The number of vehicles collected by the device A was 492, and the distance between vehicles was A2. is 18.8m. The relevant transportation department calculated and determined that n = 2243, m = 0.343, p = 0.0114

[0053] According to the algorithm

[0054]

[0055] Calculation yields V = 2243÷492 + 18.8×0.343+0.0114×800≈20.1273 m / h.
