Problems solved by technology

But they are the same as the traditional fixed road traffic signs (including variable ones), because the information is sent in one direction, the content is fixed, and the information changes slowly, so it cannot collect safety information in real time in the complex and changeable road traffic environment. , synthesis, processing, and exchange, realize two-way wireless information transmission between people, vehicles, and roads, and provide drivers with on-site road conditions and real-time safety information in a timely, accurate, and dynamic manner

Abstract

An information indicating device of road traffic safety consists of road information unit including radio frequency circuit, radio communication circuit, infrared communication circuit and control-processing circuit; vehicle information unit including radio frequency circuit, interface circuit, directional indication circuit and control-processing circuit. It is featured as enabling to carry out two-way radio frequency data communication between two said units and enabling to carry out remote data update on emission information of road information unit through radio communication network.

Description

technical field [0001] The invention relates to the field of road traffic facilities, in particular to a road traffic safety information prompting device. Background technique [0002] At present, the prompts and warnings of road traffic safety information are mainly transmitted to drivers through road traffic signs beside the road. Traditional road traffic signs that use graphics, text, and symbols to represent information have fixed and single prompt content, which cannot reflect the time-varying and uncertain road traffic conditions in a timely manner, and are easily affected by factors such as rain, fog, and driver attention. Its function of prompting safety information is greatly limited. The variable road traffic information display board using LED display technology is difficult to be popularized and applied on the whole road because of its high cost, easy wear and tear, and inability to display information in real time.
