DYNAMIC TRAFFIC FLOW MANAGEMENT SYSTEM

This paper presents an efficient priority control for ambulance clearance. Each ambulance is equipped with radio frequency transmitter (RF Tx). We use RF receiver, PIC16F877A, liquid crystal display (LCD), piezo electric buzzer were attached to the traffic signals. It detects ambulance while arriving at 100 meters before reaching the signal. In addition, when an ambulance is approaching the junction it will communicate to the traffic signal in the junction to turn ON the green light. This module uses radio frequency (RF) transmitter, receiver and PIC16F877A for wireless communication between the ambulance and traffic signal.
