Vehicle-road-person-coordinated intelligent early warning system and method for expressway traffic safety

Abstract

The invention discloses a vehicle-road-person-coordinated intelligent early warning system and method for expressway traffic safety. The system is composed of a piece of reflective clothing with an LTE-V straight-through module and a positioning system, roadside LTE-V communication equipment, and a roadside video monitoring system, vehicle-mounted LTE-V communication equipment, a vehicle-mounted millimeter-wave radar, a vehicle motion state sensing module, and a vehicle-mounted safety early-warning module. According to the invention, the protection measures and equipment are provided for driving safety on an expressway; long-distance early warning and close-distance driving behavior intervention can be carried out on a detected dangerous source; and the collision probability among the driving vehicles, operators, and persons with illegal behaviors on the expressway is reduced.

Description

technical field [0001] The invention belongs to the active safety technology, and relates to a cooperative driving safety warning technology in an intelligent transportation system, in particular to a vehicle-road-human coordinated expressway driving safety intelligent warning system and method. Background technique [0002] When the vehicle is driving on the expressway, its speed is generally between 80km / h-120km / h, and some vehicles may also experience speeding or severe speeding. If the driver has fatigue driving, limited vision, distraction, desertion, etc., it will be difficult to effectively find the workers on the expressway ahead and the pedestrians who illegally climb over the guardrail or cross the central isolation belt, which will easily cause serious traffic accidents. accidents; on the other hand, even if the driver can detect the above potential dangers, due to the limited perception range of the human eye, he cannot perceive long distances in advance and dece...

AI Technical Summary

Problems solved by technology

[0004] In view of the problems existing in the above-mentioned prior art, the object of the present invention is to provide a highway traffic safety intelligent early warning system and method based on vehicle-road-human coordination, which takes into account the current roadside communication equipment and video surveillance on the highway. The problem that the equipment does not cover the whole area solves the problem of active safety protection for the operators on the expressway and the pedestrians who illegally climb over the guardrail or cross the central isolation belt
