Bus navigation indicates which route and bus line leads from start stop to the destination stop.
I maintained the bus data through OpenStreetMap and read them at every start from an XML-Document. In order to read the file I used JDOM.
As I loaded the data somewhere in January 2020, some routes might be outdatet.
As seen here, the routes almost look like the real ones. However, they are not oriented to the north.
