TRAFFIC LIGHT CONTROL SYSTEM FOR EMERGENCY VEHICLES USING RFTECHNOLOGY

Abstract

Traffic signal monitoring and control using the 
radio frequency to monitor the traffic signal by 
linking the RFID to the Arduino. The project is very 
useful in monitoring different systems and the 
components used are Arduino nano , RF Tx, RF Rx , 
LED’s and buzzer. A circuitof three traffic lights has 
been designed for this project. The three LED’s 
used are Red, Yellow and Green. This is done to 
bring out a real time scenario of a traffic signal 
intersection. The three LED’s are powered by 
Arduino nano using jumper wires from the Arduino 
board to the breadboard where the LED’s are 
placed accordingly to represent a traffic signal 
intersection. 
The project works on Arduino control which is 
already coded inside the Arduino to detectthe RFID 
card when it passes through the sensor. The project 
is designed to read radio frequency signal from the 
card and initiate the alarm and the change in lights 
when the frequency interpretsthe sensor and 
triggers the lights and alarms to go on.Initially the 
lights are programmed to changethe colors 
periodically (just like traffic lights) and when RF Tx 
signal is detected by RF Rx reader,it changes the 
light to a particular colour is green in this case and 
the alarm also goes on.
