"A transit map is a topological map in the form of a schematic diagram used to illustrate the routes and stations within a public transport system - whether this be bus lines, tramways, rapid transit, commuter rail or ferry routes. The main components are color coded lines to indicate each line or service, with named icons to indicate stations or stops.
Transit maps can be found in the transit vehicles, at the platforms or in printed timetables. Their primary function is to help users to efficiently use the public transport system, including which stations function as interchange between lines. Unlike conventional maps, transit maps are usually not geographically accurate - instead they use straight lines and fixed angles, and often illustrate a fixed distance between stations, compressing those in the outer area of the system and expanding those close to the center."
