A Blind-Friendly Navigation System Integrating RFID Technology for Enhanced Accessibility in Public Transportation

Abstract

This paper proposes a new system to improve accessibility and navigation for people who are blind at bus stops. The system uses RFID technology, which involves RFID readers, RFID tags on buses, bus stop modules, and camera-equipped blind sticks. When a visually impaired person arrives at a bus stop, they push the switch on their blind stick to activate the bus stop module. This triggers the system to capture information about the buses, using RFID technology. As buses with RFID tags pass near RFID readers, which are located 100 meters away from the bus stop, their information is transmitted to the bus stop module. This information, including bus numbers and routes, is then announced audibly to all passengers, making it easier for people who are blind to decide which bus to take. Once the blind person boards their desired bus, the system automatically turns off to save resources. This system provides a practical solution to help people who are blind navigate public transportation systems safely and independently.
