Bluetooth technology-based traffic sign pushing method

Abstract

The invention provides a Bluetooth technology-based traffic sign pushing method. According to the traffic sign pushing method, all key points in a road section are determined and beacon base stationsare arranged in the key points, broadcast data packages of the base stations are built according to base station traffic sign classification information, base station position information, and base station node traffic sign information, and the broadcast data packages of the base stations are stored in corresponding beacon base stations; beacon base stations arranged in the road send the broadcastdata packages, and a traveling vehicle receives the broadcast data packages through a Bluetooth device; and the Bluetooth device transmits the received broadcast data packages to a vehicle pushing device, and the vehicle pushing device pushes traffic sign information according to the received broadcast data packages so as to warn a driver. Through adoption of the Bluetooth technology-based traffic sign pushing method, traffic accident rate can be lowered effectively, the driver traveling at where the visual field and terrain are unfavorable is protected, and accurate traffic sign informationis provided timely. The Bluetooth technology-based traffic sign pushing method has the advantages of low power consumption and low cost.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method for pushing traffic signs based on bluetooth technology. Background technique [0002] In recent years, with the unprecedented development of my country's urban road construction, urban roads and road networks have gradually formed, playing an increasingly important role in the development of the national economy. Traffic safety facilities belong to the infrastructure of the road network. It plays an important role in eliminating various vertical and horizontal interferences, reducing the severity of accidents, improving road service levels, providing sight guidance, and improving road landscapes. Traffic signs are an important part of traffic safety facilities. Using graphics, symbols, lines, and text of specific colors to guide, warn, plan or instruct traffic flow is of great significance to the guarantee of traffic safety. However, there are many p...
