In this paper, a density based auto traffic light control system with GSM based remote override is designed and implemented to in particular, eliminate the usual conflicting authority between the green light for the motorists/pedestrians and emergency vehicles and in general reduce very long queues of vehicular traffics at the cross-road junctions in Enugu Metropolis. Three PIC 16F877A microcontrollers, one each specifically dedicated for intelligent allocation of right of way based on vehicle densities sensing, allotting of due passage duration time, and overriding feature for emergency cases, is proposed and implemented. The traffic override is either performed by the pressure switches for density detections or the GSM module for emergency cases at any given time. The GSM remote overriding authority may be vested only on the emergency vehicle operators to override the set timing of the traffic light control system in the event of emergencies to eliminate traffic logjams and possible fatalities.

Configuration technology is a new technology for monitoring in the current society; it is the result of the development of computer control technology. To traffic light control system, it is to combine the use of configuration technology and procedures related to PLC, and through software simulation and traffic lights light changes, traffic light control system could achieve the monitoring problem, and if the system is in good condition, its application can save a lot of labor powers and materials.
