Abstract

The invention discloses a V2I (Vehicle to Infrastructure)-based road boundary and accident black spot extraction method and a system. The system comprises an acquisition unit, a road boundary pretreatment unit, a road boundary synthesizing unit, a road boundary computing unit, a road boundary judging unit, an accident black spot comparing unit, an accident black spot recording unit, a mapping unit and a sending unit, wherein the mapping unit maps a historical road boundary line database after updating and a historical accident black spot database to a map layer; and the sending unit is used for sending the map layer information to all vehicles in a road-side unit V2I communication range in real time. The method and the system have the beneficial effects that all vehicles in the road-side unit V2I communication range can be provided with the map layer information, a proposed driving path and early warning information can also be provided, the multiple vehicles can be ensured to drive in the road boundary range and avoid the accident black spots, and the accident occurrence rate can be reduced.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a method and system for extracting road boundaries and accident black spots based on V2I. Background technique [0002] The Internet of Vehicles is through the Internet technology, all vehicles can transmit various information of themselves to the central processing unit. Through computer technology, the information of these large numbers of vehicles can be analyzed and processed to calculate the best routes for different vehicles, issue reports on road conditions and adjust signal light cycles. [0003] The Internet of Vehicles includes interconnection between vehicles and vehicles (V2V), vehicles and roads (V2I, Vehicle to Infrastructure), vehicles and people (V2P), vehicles and centers (V2C), etc. Communication and roaming, guarantee real-time, serviceability and network ubiquity in terms of functions and performance, and it is a unity of public network and private network...
