Network length (transport)

As network length is the length of a traffic network is called. This may relate to different modes of transport and can be expressed in different ways depending on the definition, such as the length of the route, as line length or a length of track. The term route network is it in Switzerland often used.

Length of

The path length is the sum of lengths of all routes, such as railway lines, routes or road sections. This is thus the total length of the used transport infrastructure. Each track is independent of a possible Befahrung by several lines, a Mehrstreifigkeit, or multi-track orientation is counted only once.

Line length

In regular service, the network length can also be specified as line length. This is calculated as the sum of the length of all lines of a transport system. Routes which are shared by several lines are thus counted repeatedly. The line length is therefore always greater than or equal to the length of the route.

Track length

In rail transport, the track length is given as a measure of the network length. Here, the length of all tracks belonging to a transport network is specified. Thus, a double-track line has a route length compared to twice the length of track.

Calculation example

The tram network a small town has two lines. Both lines begin at point A, go on a common path 5 miles to the point B. There, the journeys of the two lines share 1 takes another 5 miles to the terminus at Point C, line 2 ends after also a 5km at the point D. The entire route network is two-pronged, there are 1 km Depot and operating railroad line without traffic.

The distance is:

5 km ( A → B) 5 km (B → C) 5 km (B → D) -------    15 km The line length is:

10 km ( A → B → C, line 1) 10 km ( A → B → D, line 2) -------    20 km The track length is:

10 km ( A → B, each double track ) 10 km (B → C, each double track ) 10 km (B → D, each double track ) 1 km (operating routes ) -------    31 km References
