    This project demonstrates intelligent traffic control with capability of controlling the traffic flow according to the varying situations of traffic flow with the help fuzzy logic. The control of traffic is done using 8051 microcontroller. The fuzzy allows the 8051 to take decisions according to number of vehicles on each road and as a result control the timing of green signal of the respective lanes. The input to the fuzzy is number of vehicles, given into the system by a PIR sensor. The intelligent traffic control does not restrict to only control of 3 lights, but also gives freedom to take decision during emergency situations, such as giving way to fire engines and ambulance vehicles. The project is demonstrated by three different modules. Module 1 demonstrates the traffic light working with the fuzzy input vehicles in 4-road junction. The system classifies the traffic into 4 types: isolated, light, medium and heavy. The number of vehicles is put into either one of the categories and the timing of the green signal varied based on the category. If emergency is detected, then the green signal of the respective lane is made to blink for a considerable long duration, so that the emergency vehicle leaves the junction. Module 2 employs a Passive infrared sensor that detects motion. This PIR sensor is used to count the number of moving vehicles and the number is displayed on a 16X2 LCD display. This serves as the input to the fuzzy code. Module 3 demonstrates the detection of emergency vehicles. It employs a RF transmitter and receiver. The RF transmitter is placed on the emergency vehicle, and the receiver at the traffic junction. When the transmitter is in the range, and receiver detects the vehicle, receiver initiates the emergency signal. It sends a emergency message to traffic control room on a 16X2 LCD display.
