Smart Traffic Light Control System with Automatic Vehicle Speed Breaker
Abstract
The aim of the project is to design a smart traffic light control system interfaced with a barrier gate and a LDR based traffic light control system. When signal timing changes by delay is provided with the help of microcontroller, barrier on zebra crossing will open or close to allow vehicles to pass. When the signal is red the interfaced barrier gate closes and a buzzer notifies the closing of gate, thereby blocking the traffic but when the signal is green the same barrier opens and allows a proper flow of vehicles to avoid traffic jam. We provided time delay for all signal to change and buzzer action by using AVR microcontroller. In front of the barrier gate a stop line is drawn and with the help of another IR sensor, the vehicle is tracked whenever it crosses the stop line. AVR microcontroller is used for signal timing change as well as street light control according to LDR.
