Early warning method and system of two kinds of passenger cars and one kind of dangerous goods transport vehicles based on vehicle-road cooperation technology

Abstract

The embodiment of the invention discloses an early warning method and system of two kinds of passenger cars and one kind of dangerous goods transport vehicles based on the vehicle-road cooperation technology, and relates to the field of the vehicle-road cooperation technology. The early warning method comprises the following steps: a roadside unit RSU obtains information of two kinds of passengercars and one kind of dangerous goods transport vehicles entering high speed road sections, wherein the manner the RSU to obtain the vehicle information comprises: a manner in which the two kinds of passenger cars and one kind of dangerous goods transport vehicles actively upload the vehicle information, or a passive obtaining manner by a roadside sensing device; the RSU reports the obtained information of the two kinds of passenger cars and one kind of dangerous goods transport vehicles to a road network monitoring center; the road network monitoring center performs real-time positioning and tracking on the two kinds of passenger cars and one kind of dangerous goods transport vehicles by using a positioning system; the road network monitoring center judges an early warning RSU based on thereal-time locations of the two kinds of passenger cars and one kind of dangerous goods transport vehicles, and issues early warning broadcast information to the early warning RSU; and the early warning RSU issues the early warning broadcast information to the traveling vehicles on the road sections. By adoption of the early warning method and system disclosed by the invention, the problem that noeffective means is available to make reasonable control and early warning on the two kinds of passenger cars and one kind of dangerous goods transport vehicles in the prior art, resulting in a high road accident rate can be solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle-road coordination, and in particular to a method and system for early warning of two passengers and one dangerous vehicle based on vehicle-road coordination technology. Background technique [0002] "Two Passengers and One Hazard" refers to chartered vehicles engaged in tourism, passenger vehicles of Class 3 or above, and special road vehicles for transporting dangerous chemicals, fireworks and firecrackers, and civilian explosives. The two-passenger-one-danger vehicle has a great potential safety hazard because of its large passenger capacity or dangerous goods in the driving process. Once a traffic accident occurs, it will often cause serious consequences such as heavy casualties or property losses. [0003] Moreover, with the continuous development of industry technology, automatic driving has gradually become the ultimate goal of the future transportation industry. I...
