Road traffic accident chain blocking system based on Internet of Vehicles

Abstract

The invention discloses a road traffic accident chain blocking system based on Internet of Vehicles and relates to the field of intelligent traffic management and control. The road traffic accident chain blocking system is characterized in that multi-source driving state information is transmitted to a blocking information processing center which comprises a standardized driving state data generating module, a driving state data storage module, a blocking expert database and a blocking cloud computing platform, the standardized driving state data generating module receives the multi-source driving state information, performs multi-source information fusion, outputs standardized driving state data which can be directly processed by the blocking cloud computing platform and comprises set attributes and transmits the standardized driving state data into the driving state data storage module and the blocking expert database, the driving state data storage module performs limit-time storage on the received data and transmits the data to the blocking cloud computing platform, the evolution law of a traffic accident chain is extracted from the evolution and development angle of a whole road traffic accident, and the traffic accident chain can be blocked effectively before the road traffic accident by utilizing the evolution law.

Description

technical field [0001] The invention belongs to the technical field of traffic intelligent management and control, and specifically relates to a road traffic accident chain blocking system, which can effectively block the accident chain at the initial stage of road traffic accident risk, so as to improve road traffic safety and reduce road accidents. The incidence of traffic accidents. Background technique [0002] In order to prevent personal injury caused by road traffic accidents, anti-collision systems are generally installed on vehicles. Traditional vehicle anti-collision systems are mainly composed of three parts: information collection terminal, information processing and decision-making center, and decision-making execution terminal. Among them, the information collection terminal passes The sensor equipment detects signal information such as the driving speed of the vehicle, the distance between the vehicle and the obstacle, and the driver's manipulation behavior, a...

AI Technical Summary

Problems solved by technology

This traditional vehicle anti-collision system mainly has the following problems: ①The control decision of the anti-collision system is based on the collision time based on vehicle speed and relative distance or the minimum safe vehicle distance based on the analysis of vehicle braking kinematics as the early warning parameter. The thresholds of early warning parameters establish different early warning or control strategies, which belong to the decision-making mechanism based on time and distance parameters; in fact, the entire evolution process of road traffic accidents is divided into the early dange
