Line network plan
There are different forms, for example total network, rapid transit, night network, city and regional transport plans. The lines on the plans can be shown schematically or topographically , sometimes they also contain information about places of interest and leisure facilities. In some cases, information on the tariff (tariff cells, tariff zones), the frequency of operation ( clock frequency , school lines , traffic times ) or connection points are also shown . To differentiate between individual lines or modes of transport, different colors and line widths are used and the line numbers are placed on the corresponding route displays.
Simplified line network schemes with large corner radii are perceived to be clearer, but do not offer any orientation that allows use outside of the means of transport. This is achieved by traffic route maps , which, in addition to the (often simplified) representation of the urban landscape with its local and road network, including the name of the goods, include the traffic routes with their geographically correct stops , sometimes also with their names. Important destinations such as government offices and leisure facilities (e.g. swimming pools) are also listed here. A good choice of colors for the various map elements is very important to achieve a better overview.
Especially in Berlin the line plans is the name given to the simplified overview schemes web spider or shortly spider used. It is used, for example, as a name for the Berlin U- and S-Bahn network plan. The first network map of the elevated and underground railway was published there in 1914.
The renunciation of topographical accuracy in favor of a clearer and space-saving design was revolutionary. In 1931 a route network plan was published for the Berlin S-Bahn with a circular representation of the ring route and otherwise horizontally, vertically or at a 45 ° angle with stations arranged at regular intervals. In the route network maps of the London Underground (the so-called tube map ), first designed by Harry Beck in 1931 and published from 1933, each underground line was also represented by a graphic line of its own color. This model became the model for schematic line network plans in many other cities.
