Transit map

A network plan is a topograph of lines of public transport network. There are different shapes, such as total power, rapid transit systems, nighttime network, urban and regional transport plans. The lines on the plans may be shown schematically or topographically, sometimes they also include information on attractions and recreational facilities. Shown are partly Information on tariff (tariff honeycomb, zones ), the frequency of operation ( switching frequency, student lines, rush hours) or tie points. To distinguish individual lines or modes of transport, different colors are used.

From the Berlin parlance, the name comes web spider or short: Spider found there as a term for the U- and S-Bahn network originated. The first network of elevated and subway was published there in 1914.

Revolutionary was the absence of topographical accuracy in favor of clearer and space-saving design. 1931 route network plan was for the Berlin S -Bahn published with circular representation of the ring route and otherwise horizontally, vertically, or running at a 45 ° angle lines with stations arranged at regular intervals. In the first time in 1931 by Harry Beck designed and published from 1933 line network plans of the London Underground also every subway line was represented by a graphic line their own color. This model became the model for schematic line network plans of many other cities.
