TRAFFIC CONTROLLER BASED ON RF

Abstract

The project aims to provide a rational reaction for the traffic signal system to routinely refuse the
usual sign timings during emergencies. When there is an emergency situation, such as a fire department or
crisis car trapped in rush hour traffic, people tend to think that need should come first. In addition, the
necessity becomes apparent when a certain route acquires excessive thickness. Hence, the system makes use of
an android application device remote control that effectively offers a green piece of information for vehicles
travelling in that direction and a red sign for all other traffic. The project makes use of an 8051 family
microcontroller that is connected to IR sensors and photodiodes that are evenly distributed across the shop to
see the thickness. The thickness is measured using three distinct methods: low, medium, and high, as
indicated by the durations that are suitable for sign. RF advancement is used for the management of the
replacement.
