The Travel Assistant Device (TAD) mobile application grew out of a research project conducted at the University of South Florida’s National Center for Transit Research [1] [2]. The travel assistance system for sight-impaired or intellectually-disabled passengers allows them to plan a transit trip and download information to a GPS-enabled mobile phone with the TAD mobile app installed. Phones with the application installed give audio and vibrating alerts when it is time for the passenger to pull the stop cord and alight from the bus.

The TAD system uses GTFS data to import up-to-date schedule and stop. The product is being commercialized by DAJUTA [3], a Florida-based company. Updates on the TAD project can be found at the USF TAD website [4].
