Smart bus boarding system for visually impaired passengers

Abstract

There are 161 million people visually impaired out of 6.7billion people in the world. Each visually impaired individual faces different challenges based on their specific level of vision. With the rise of various support-based organizations, more visually impaired people have been given the opportunity to education and many other means. But still the issues of navigation for the blind are very complex and troublesome especially when they walked down in street and also navigate to distant places by public transport system. In this project we propose a Passenger bus boarding system using wireless networks . The visually impaired passengers are provided with a RFID tag which containes the information of the passenger and also its destination information. The Bus stops containes RFID reader and a RF module of 2.4 GHz frequency along with their master controller installed in the sits of the stop. The RFID reader will recognize the Visually impaired passenger by his RFID tag and forwards its destination information to the microcontroller, which will process the information and waits for the bus arriving signal from the RF module. When the bus, that also contains one RF module with its microcontroller comes into the range of bus stop, the RF module at the bus stop will recognize the bus no. and forwards it to the microcontroller. The microller will compare the data of the bus no and passenger’s destination and generate the alert signal accordingly to the voice module, by getting the voice alert the Passenger will know that their bus has arrived or not. The driver at the bus will also get notification of the Visually impaired Passenger through LCD installed in the Bus unit.
