Traffic light control systems are widely used to monitor and control the flow of automobiles through the junction of many roads. However, the synchronization of multiple traffic light systems at adjacent intersections is a complicated problem given the various parameters involved. Conventional systems concentrate mainly on allotting equal time to all the lanes. In addition, the mutual interference between adjacent traffic light systems, the disparity of cars flow with time, the accidents, the passage of emergency vehicles, and the pedestrian crossing are not implemented in the existing traffic system. This leads to traffic jam and congestion. The paper propose a system based on ATMEG32 microcontroller that evaluates the traffic density using Laser sensors and accomplishes dynamic timing slots with different levels. Moreover, a portable controller device is designed to solve the problem of emergency vehicles stuck in the overcrowded roads and notifying the vehicles the current traffic scenario.
