The mobile app is the beginning of a bigger system that would make public transportation in Rome (and in other cities) a much better experience.
Data collected from the app will allow organizing the transportation system like never before. Planning bus stops and routes will be no more a guess work but an analytic decision taken from actionable and constantly updated data.
A smartphone is just one of the many ways a user can interact with the app, the same results can be achieved through a bot or vocal assistants like Siri or Alexa.
