AI Technical Summary

Technical Problem

Conventional road lighting systems face inefficiencies in power consumption and visibility due to uniform illumination across all road sections, inability to predict vehicle movement paths, and inadequate response to emergency vehicles, leading to increased energy use and potential delays.

Method used

A road lighting system that predicts vehicle movement paths and selectively controls lighting based on predicted paths, enhances visibility for emergency vehicles, and separates power supplies for normal and emergency lighting.

Benefits of technology

The system reduces unnecessary lighting and power consumption, optimizes energy use based on vehicle speed and road curvature, and ensures timely visibility for emergency vehicles, improving safety and efficiency.

Abstract

The present invention relates to a road lighting system based on vehicle movement path prediction for improving power efficiency, comprising: a vehicle detection unit installed at multiple points on a road to collect information on whether a vehicle has entered, driving speed, and vehicle identification; a movement path prediction unit that analyzes information collected from the vehicle detection unit to predict a vehicle's driving path or a possible branching path; an emergency situation determination unit that determines whether a vehicle is an emergency vehicle or an accident based on information collected from the vehicle detection unit; and a lighting control unit that selectively turns on or controls the illumination of streetlights in a road section corresponding to the vehicle's driving path or the vehicle's branching path predicted by the movement path prediction unit. The lighting control unit is characterized by individually controlling a main lighting unit provided in the streetlight and a warning lighting unit provided in the streetlight but separated from the main lighting unit when it receives an emergency situation signal from the emergency situation determination unit.
