App design concept for the Bucharest subway system

I thought it would be a good exercise to think about an app that shows real-time info about the subway system in Bucharest, depending on your location. The colors represent the Romanian flag as well as the main subway lines as they currently are. One great feature of the app would be the ability to buy tickets and use NFC to enter the station, which is currently possible but not implemented, as the Bucharest subway has been updated with new gates. I am thinking of continuing this series with station info panel concepts, street signs and more. What do you think?
