Network length (transport)

A measurement can be made of the network length of various different modes of transport, including rail, bus, road and air.

Continental European and Scandinavian transport network analysts and planners have long had a professional practice of using the following terminology (in their own languages) to draw a distinction between: In 2000, this terminology was adopted by an English language best practice guide to public transport, to minimise the risk of confusion.

[1][2] Since then, a number of other English language specialist publications have adopted the same terminology, for the same reason.

The U.S. Department of Transportation's Federal Transit Administration has also referred to this as "Directional Route Miles (DRM)".

If a network is made up of railways, tramways, or a combination of the two, its track length may also be calculated.
