The main use of traffic signal is to provide information that is the key to safe and smooth traffic flow. For most of the time traffic signals have existed, their design and construction have remained quite constant. This device is vehicle “ density adjusted with LED light sources, because LED light uses less energy than their incandescent counterparts. The device makes use of LED light sources, which are programmed to flash signals to the oncoming drivers to reduce collisions. All the lamps are given numbers and the specified number that is taken becomes active depending on the direction chosen. These are controlled by a microcontroller which acts as a supervisor, for the activities taking place in the system.
