Public Transportation Assistance for Blind Using IOT

Public transportation assistance device for the blind is aimed at providing an assistance to the visually impaired in effectively utilizing the public transportation system by identifying his/her suitable vehicle for boarding, avoid unwanted ones. The use of multiple RF modules allows the blind to access more locations. The work involves using RF transmitter and receiver which uses a 433 MHz frequency band to transmit and receive signals between the bus and blind person. The haptic feedback motor is used to generate vibrations according to the messages received which informs the blind to get ready for boarding the vehicle. The work involves designing and building a prototype system that uses these transceivers. This technology improves the quality of the life of the blind people to go to the important places on their own using the public transport facilities. The technology can be extended to many more places as per the person’s wish using different frequencies. Result: This public transportation assistance device for the visually impaired enhances independent travel by identifying the correct vehicle for boarding and avoiding incorrect ones. Multiple RF modules enable access to more locations, using a 433 MHz RF transmitter and receiver to exchange signals between the bus and the user. Haptic feedback through a vibration motor alerts the user when their desired vehicle arrives, allowing them to prepare for boarding.
