A GPS-based traffic warning method and system

Abstract

The present invention provides a traffic early warning method and system based on GPS. The method includes: periodically acquiring the position information of the first target and the second target; calculating the distance between the first target and the second target according to the acquired position information The actual distance between; compare the actual distance with the preset distance threshold, if the actual distance is not greater than the preset distance threshold, it is judged that the first target and the second target are within the preset Whether there is a possibility of collision within the distance threshold radius; if there is a possibility of collision, an early warning signal is sent to the first target and the second target; if there is no possibility of collision, no early warning signal is sent. The present invention further judges whether to send an early warning signal to remind both parties to pay attention to slow down or avoid by judging whether the routes of the two parties may collide when people and vehicles, or vehicles and vehicles approach each other, so as to achieve the purpose of safe travel.

Description

technical field [0001] The invention relates to the technical field of traffic management and information service, in particular to a GPS-based traffic warning method and system. Background technique [0002] In the increasingly urbanized modern life, people, motor vehicles and non-motor vehicles will appear in the same public domain on many occasions, and traffic accidents may occur if you are not careful. For example, when there are obstacles such as construction sites or billboards on the side of the road, or at intersections with poor visibility, if pedestrians or vehicles cannot identify the road conditions at the first time, they are very likely to collide due to insufficient avoidance. [0003] The traditional way to solve the above problems is generally to set up traffic signs and other signs that mainly play a prompting role in areas where traffic accidents are prone to occur. However, with exposure to the sun, rain, wind and rain, these signs are often damaged by ...

AI Technical Summary

Problems solved by technology

However, with exposure to the sun, rain, wind and rain, these signs are often damaged by fading, corrosion, etc., making it difficult for people to recognize their contents normally

Obviously, this kind of method puts pedestrians or driving vehicles in a relatively passive position, and cannot flexibly and effectively ensure safe travel.
