Abstract |
This article proposes a mechanism to reduce the battery power consumed by an independent solar-powered light intensity detection (LED) used for auxiliary traffic sign lighting by means of special background light sensor detection and an LED brightness control. This kind of traffic sign is deployed in remote areas and public utilities, where workers find hard to reach. Symbols and signs shaped by LED lights can assist drivers in mountain areas, remote areas, roads and highways with indications of directions and/or speed limits such that traffic accidents can be reduced. LED lights are especially suitable for environments with poor lights. |
