Researchers Are Developing Smart Streetlights That Automatically Switch On And Off As Cars Pass
When you were growing up, how many times were you prompted to “turn off the lights when your not using them!”? It’s a habit many parents try to instill in their children. All that wasted electricity can rack a serious energy bill! Researchers at the Institut Teknologi Bandung in Indonesia know this all too well. They are developing smart streetlights that automatically turn on as vehicles approach, then turn off after they have passed.
The Automatic Road Lighting System (ARLS) is currently being tested with a video camera, light source, PC and toy car. The video camera is used to capture images of the toy car as it rolls into frame. Those images are then analyzed by the PC to determine the car’s speed and location. The computer uses this data to determine when to switch the light on and off.

Indonesia’s city of Jakarta has over 200,000 street lights! Those babies consumed $17 million of electricity on 2007. Think of the money they could save with this technology! Hopefully these new smart lights will enter production in the near future.
