Braille bus notification buttons

How can public transport commute be made simpler for persons with impaired vision?

Real time data on map services is often unreliable while availing public transportation.This can add to the challenge of commuting for visually impaired individuals. The proposed system allows a user to select the route they intend to travel at the station, by pushing a 3D printed button with numeric and Braille embossing. An immediate audio feedback is provided to the user to inform that the input was successfully registered.

We incorporated color coded LEDs to inform the driver of the approaching vehicle that the service is requested by someone with special needs. As soon as the vehicle enters the terminal, the driver can trigger an audio notification using a mobile app that the vehicle has arrived and can make sure that the commuter is able to avail the service.
