The problem of traffic congestion due to the rapid increase in the number of vehicles passing through Sango - Polytechnic Ibadan Junction has led to this design, ‘Sensor-Based Traffic Light Control System’.This system is designed to coordinate the smoothness of traffic during the peak hours (between 7:00-8:30am & 3:00-5:00pm) during the working days (Mondays-Fridays). The traffic light system is designed using Programmable Integrated Circuit (PIC) F1508/9 Microcontroller as the major component, Phototransistors and Infrared LEDs as Sensors for effective traffic control. The PIC is implemented via an IC programmer using a micro-C language. The developed traffic light control system worked according to specificationsusing a prototype that resembles the real application. The System gives priority to congested traffic rather than the usual fixed-time operations.  It is however recommended that the design be solar powered and more sensitive sensors such as the RFID be used to improve upon this design.In conclusion, the functionality of the prototype shows that the developed system can be used for a real life traffic control at road intersections. Besides it can be used as a teaching aid in schools and road safety agenciesfor various road users.
