An Intelligent Traffic Signal System for Ambulance Priority Using Internet of Things
Main Article Content
Abstract
Introduction: Modern metropolitan surroundings face a great deal of traffic congestion, which is made worse by an increasing number of vehicles and a growing population.
Objectives: This proposed study seeks to alleviate this problem by introducing an innovative system that empowers ambulances to interact with traffic signals, accelerating their progress.
Methods: The Arduino ATMega 2560 microprocessor, Light Emitting Diodes (LEDs), and traffic signal relay are the key components of the system that work together to alert users to the presence of an approaching ambulance and modify the traffic signals. The proposed device turns the nearby traffic signal green and initiates a blue and green light sequence to indicate the ambulance's arrival. In the receiver component, a Bluetooth HC-05 module is employed to facilitate communication. Through a specialized program called Bluetooth Terminal HC-05, users can send signals to the traffic light system informing it of an approaching ambulance.
Results: The findings of the simulation verify that the proposed system is capable of quickly detecting the presence of an ambulance and effectively modifying traffic signals.
Conclusions: It may be easily installed on different road networks because to its affordability.
