Early warning method, server and system for highway shunting area

Abstract

The embodiment of the invention discloses an early warning method, server and system for an expressway shunting area, and the method comprises the steps: judging whether a target vehicle has a backing behavior or not through the real-time collection and analysis of the driving data of the target vehicle at a road section in front of the shunting area, and when the target vehicle has the backing behavior, giving an early warning. And the dynamic reversing duration, the dynamic early warning distance and the shunting area lane type of the target vehicle are obtained through real-time analysis, early warning areas are generated, and the early warning equipment is controlled to play different early warning information for different early warning areas. According to the driving condition of the target vehicle, the rear vehicle is guided and adjusted in real time, and the rear vehicle is prevented from colliding with the target vehicle or causing congestion.

Description

technical field [0001] The invention relates to the field of highway safety management, in particular to an early warning method, a server and a system for a highway diversion area. Background technique [0002] The highway scene is complex, and the diversion area is a common accident-prone area on the highway. According to statistics, the total length of highway interchanges or ramps accounts for less than 5% of the total mileage, but the number of accidents is as high as 40%, and the fatal accidents are 11%. 50% of the accidents at the entrance and exit sections of the expressway occurred on the exit section, 34% occurred on the entrance section, and 16% occurred on the connecting section. [0003] Some vehicles drive in the wrong direction after passing the diversion intersection, and take dangerous measures such as reversing and changing lanes to change the direction of travel, which will cause traffic accidents such as rollover, rear-end collision, collision with guard...

AI Technical Summary

Problems solved by technology

[0003] Some vehicles found that they were driving in the wrong direction after driving through the diversion intersection, and took dangerous measures such as reversing and changing lanes to change the direction of travel, which caused traffic accidents such as rollovers, rear-end collisions, collisions with guardrails, and lane queuing congestion, resulting in greater life and property loss

[0004] In the existing technology, when the vehicle in front is reversing, it often only informs the car coming from behind how many meters there is a reversing behavior in a certain lane ahead, and it is difficult for vehicles in other lanes to respond correctly to this. The diversion area is chaotic and congested, and often occurs when the rear vehicle brakes and the rear vehicle does not brake in time and rear-ends
