Traffic early warning method based on GPS and traffic early warning system based on GPS

Abstract

The present invention provides a traffic early warning method based on a GPS and a traffic early warning system based on the GPS. The method comprises the steps of obtaining the position information of a first target and a second target periodically; calculating the actual distance between the first and second targets according to the obtained position information; comparing the actual distance with a preset distance threshold value, if the actual distance is not greater than the preset distance threshold value, determining whether the first and second targets are possible to impact in a radius range of the preset distance threshold value; if yes, sending an early warning signal to the first and second targets; if no, not sending the early warning signal. According to the present invention, when people and vehicles or the vehicles approach each other, by determining whether the paths of the two parties are possible to impact, the early warning signal is further determined whether to be sent to remind the two parties to slow down or avoid, thereby achieving the safe travel purpose.

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 ...
