Real-time road safety prompting system based on vehicle behaviors and prompting method thereof

Abstract

The invention discloses a real-time road safety prompting system based on vehicle behaviors and a prompting method thereof. The method comprises the steps of firstly carrying out the parameter information collection of each vehicle in a monitored road segment through roadside radar vision equipment, and inputting the collected parameter information into vehicle behavior identification equipment, identifying and grading the position and behavior of each target vehicle through a built-in identification algorithm, then inputting an identification result into a corresponding signal prompting lamp of the target vehicle, enabling a signal prompting lamp control unit to control the initial angle and the rotation angular speed of the prompting lamp in real time according to information such as the position and the speed of the target vehicle, and locking and tracking the target vehicle, enabling the control unit to control the prompting content and color switching of the prompting lamp according to the behavior identification result of the target vehicle, and enabling the built-in light sensor of the prompting lamp to obtain the brightness of the ambient light of the road in real time, and adjusting the light of the prompting lamp through the control unit. Finally, the whole-course tracking prompting early warning of each target vehicle in the monitored road section is finally realized.

Description

Technical field [0001] The invention belongs to the field of Intelligent Vehicle coordinated transportation system, especially in a real-time alert system and road safety tips based on vehicle behavior. Background technique [0002] In recent years, with increasing car ownership, there followed a series of traffic safety problems, this has been the government and society are highly valued. According to incomplete statistics, in the form of a large number of traffic accidents, the vehicle the attrition accounted for nearly half percent. Numerous studies show that the attrition in an accident, if the driver of the vehicle behind to take timely measures, can effectively prevent most accidents. Therefore, timely and effective detection and alert the vehicle speed is abnormal, with Chi abnormal behavior, is of great significance in reducing the incidence of traffic accidents, save lives and property losses, improve traffic safety. [0003] Bound by the technical level, the application...

AI Technical Summary

Problems solved by technology

[0003] Constrained by the technical level, the application of vehicle-road coordination technology is not mature enough at this stage. At present, the most common way to remind the driver is through sound and light such as speakers, buzzers and display screens installed on the roadside. equipment

The erection position of these devices is fixed, and there are limitations to the reminder of the driving vehicle. The reminder information is easily blocked by other vehicles and it is impossible to track the vehicle for a long distance.

Prompt devices such as audio and buzzers are prone to noise pollution, and will make drivers nervous and affect driving behavior

[0004] At present, there are similar projection reminder functions in some smart cars, but this function cannot be used for traditional cars that occupy the vast majority of the total. Provides a good solution for the prevention and control of traffic accidents
