T-Junction traffic light using IR sensor

The traffic light is signaling devices positioned at road intersections, pedestrian crossing, and other locations to control flows of traffic. There are different types of traffic light such as 4 ways traffic light and T-junction traffic light. For our project we have an idea of doing T - junction traffic with IR sensor at the minor road. This project reduced the traffic congestion that usually happened at the minor road due to the drivers need to make sure that the main road is clear and safe to crossover the road. The main road also normally always busy, so this will effect the drivers on the minor road. By placing the IR sensor at the minor road, it will send the signal to the traffic light to give them crossover the road and set it around 15 seconds. The purpose of this project is to give some advantages towards minor road users. Therefore, improvising the T- junction traffic light needs to be done by bringing in the T-junction traffic light using IR sensor. This IR sensor will detects the presence of vehicle at the minor road and send the signal to the system that had been programmed into a microcontroller (PIC16F877A). Besides that, output devices such as LED, BCD decoder and 7 segment display is implemented into the system.
