The main goal of this project is to provide efficient solution for traffic signal system to overcome the problems that occurs with normal signal timings during emergency automatically.
The emergency situations are like ambulance, fire brigade gets stuck in traffic .This vehicle needs priority to go first as well as the requirement occurs when there is high density at a particular direction.
The system work with AVR family Microcontroller that is interfaced with the IR sensors and photodiodes aligned in line of sight configuration across the load for detecting the density.
The system featured with android application device remote control that overrides the signal timings by immediately giving green signal in the vehicle direction and red signal for all others.
The density is calculated in three ways such as low, medium and high according to timings are allotted for signals.
The timing overridden is done using Bluetooth technology in android device.
