Now-a-days the amount of power consumed by street lighting shares a major part of energy demand. The traffic is high in some places and in other places of less density areas traffic will be low. But during night all street lights will be ON in conventional street lighting system. To overcome from this issue, proper energy saving methods and lighting control has to be implemented. In the proposed work we have two controls like, one is to switch OFF lights duringnovehicularmovementinstreetsandautomaticallyswitch it ON when vehicles arrive and the other modes are to give less intensity light for pedestrian and to switch ON bright mode during vehicle moments at sides on the roads. In this work the LED lights are used for street arrangement, the photo diodes and IR sensors are used to sense vehicular movement. The control signals of sensors have been fed to microcontroller 8051. In the microcontroller the control logic is implemented to control lights based on vehicular traffic and pedestrian movement with bright and dim mode of operation and to switch off lights during no vehicular traffic and pedestrian movement. From the proposed method the overall energy beingutilizedforlightingcanbeminimized. Moreovertheautomatic and intelligent control schemes are required to control the complex lighting system due to energy saving implemented in development of smart cities for the future and raise the standard of living for a cleaner and greener future
