Traffic light automation is the process of scheduling the traffic light signals without or minimal human
intervention. Automated vehicle traffic control system that combines traditional traffic lights with an
array of sensors to intelligently rout vehicle. The most common traffic light signals works on simple
timers where the traffic light will cycle through green, yellow, and red at regular intervals. Those timer-
based systems are best suited for busy areas where the traffic volume is heavy and consistent. On the
other hand sensor-based traffic light signals rely upon the density of the vehicle detected by an array of
sensors to rout the vehicle intelligently rather than depending upon the clock time. In addition to
inductive sensors there are also over-the road sensors that can use infrared, laser, acoustic, or visual
technologies to detect the presence of vehicles at traffic signals. Those sensor enabled system works
excellent in those areas here the timer-based system does not work well such as the area where the
volume of the traffic is unpredictable and sporadic or not equal in all the directions.
