Regular bus
A regular bus line has a starting point and final destination, and runs according to a planned timetable and a route with a fixed set of bus stops.
Bus lines
The regular bus lines are identified by a line number on the front of the bus. The line numbers also have their own colour: this is visible on the line map of each transport area (also called 'concession').
Line network map
A line network map is a map of a transport area with all the bus lines, the routes they travel and the locations of the bus stops.
