Most traffic control systems in use today operate on a simple timing mechanism that changes the lights after a given time interval. This is not maximally efficient as all lanes on intersections do not have the same traffic volume. This paper reports the design and implementation of a model of a Sensor Based Intelligent Traffic Control System. The design was achieved using infrared sensing mechanism, an AT89C51 micro-controller and actual C programming, as the decision/control unit and neon lamps switched by relays for the indicator section. The system developed is able to sense the presence or absence of vehicles within certain range, measure the traffic volume rate, then make decisions on which lane to best direct the traffic in the region by dynamically assigning allowed times (time for the green lights to remain illuminated) to each of the lanes. After construction and testing, it was observed that the allowed time allocated by the system to the different lanes was directly dependent on the volume rate at which vehicles ply the various lanes.
