Design and Fabrication of a Smart Traffic Light Control System

Although the importance of traffic lights which give safety to the users on roads, the traffic jam causes great loose in time and energy (fuel) for some people, while others crossing road or roundabout have no traffic jam. The main objective of this paper is to design and implement a suitable algorithm and its simulation for an intelligent traffic signal simulator. The system developed is able to sense the presence or absence of vehicles within a certain range by setting the appropriate duration for the traffic signals to react accordingly. By employing mathematical functions to calculate the appropriate timing for the green signal to illuminate, the system can help to solve the problem of traffic congestion. The reason depends on resent fixed programming time. So, our target in this paper is to make this time unfixed according to the size of traffic jam, When there is a traffic jam in any road the green light which means permeation gives full time to the user of the road. If there is no traffic jam, the green light does not give full time, but it gives programming time. The new timing scheme that was implemented promises an improvement in the current traffic light system and this system is feasible, affordable and ready to be implemented especially during peak hours. In general, the system works adequately, as foreseen in the design process. Key-Words: Traffic lights, PLCs, Lab VIEW, Matlab, Sensors
