Street Lighting Energy-Saving System

Public street lighting can account for a large part of the total bill in typical cities worldwide. It is a key consideration for any government from several perspectives. These include environmental, safety, and economical issues. Nowadays, all the lights on the roads stay switched ON all night long. Hence, a massive amount of energy is wasted when there are no vehicles on the road. However, street lights are not necessary if there is no traffic on the road at night. As natural energy resources are limited, it becomes necessary to look for solutions to save energy; in particular, reduce energy consumption in street lighting. This paper proposes a smart system to control the street lighting and reduce energy consumption. It is intended to observe vehicle's movement on the road and turns ON a block of street lights ahead of vehicle. As the vehicle passes by, the system turns OFF the trailing lights. In addition, the system will control the intensity of light. Hence, a decrease in electrical consumption while a sustainable street lighting is ensured.
