Startup Idea : Bus route on map

Many of the bus stops now have bus routes indicated on the panel at the back. They are all in text form. Apps on handphone apps normally helps you to get from point to point and is able to tell when is the next bus arriving. However, there is nothing to help a person know where will the buses go to when it arrives. Not all people arriving at the bus stop knows where they are and thus the apps are useless when they want to go to the nearest rail station or nearest location they know. Showing the various bus routes at the station on the handphone map will help very much in this case.
