This is an example of a City Subway Map. A transit map is a topological map in the form of a schematic diagram that depicts the routes and stations of a public transportation system, such as a bus, tram, rapid transit, commuter train, or ferry route. The major components are color-coded lines that represent each route or service, together with labeled symbols that represent stations or stops. The major aim of a transit map is to assist passengers, particularly those inexperienced with the system, in taking the right routes to go between two destinations; this may entail changing vehicles or modes of transportation throughout the trip.
