The project aims at designing an intelligent traffic control system which is capable of estimating traffic density using IR sensors and then counts the number of vehicles with the help of IR sensors.  The system makes use of IR sensors and High power LED‘s as traffic lights and microcontroller.   Automation has created a bigger hype in the electronics. The major reason for this hype is automation provides greater advantages like accuracy, energy conversation, reliability and more over the automated systems do not require any human attention. Any one of the requirements stated above demands for the design of an automated device. The energy conversation is very important in the current scenario and should be done to a maximum extent where ever it is possible. Energy can be effectively conserved if we can control the traffic lights on the highways by glowing them according with time delay.   In this project, when the smoke sensor’s threshold value exceeds 8000ppm, the green light gets ON automatically. It remains in ON state for a predefined amount of time. The number of vehicles are counted using IR sensors. After the predefined amount, the signal turns to red.. The PIC Microcontroller used here is programmed by Embedded C language.

1. Automatically controlling the traffic lights
2. Traffic density estimation.
