The project aims to provide an effective solution for controlling traffic signals according to the density of traffic at junction. Higher density traffic requires longer green signal than the one with low density hence the system serves this purpose.
The project uses a microcontroller of PIC16F8 series that is interfaced with the IR sensors and photodiodes aligned in line of sight configuration across the load for detecting the density that changes the junction timings. The density is measured in three ways low, medium and high according to which the timings are allotted for signals
