Street category

The term road category (also road class or road system ) describes the classification of a road within a road network with regard to the road construction load , the design standard and the usage restriction.

If roads are classified according to the road construction load, the road network is divided according to the road construction load carrier on the basis of the applicable road laws . In Germany , for example, public roads are categorized at federal level into federal autobahns and federal roads , and at state level into state roads , district roads and municipal roads . Austria and Switzerland ( national road , cantonal road , municipal road ) have a similar categorization. The classification is given in Germany by the relevant road and route laws .

If one looks at the structure of the road network according to design standards, various properties, such as the function (connection, development or stay) of the road as well as its location (urban or out of town) and surroundings (cultivated or cultivated), are important for the classification. This type of road categorization is specified in the road construction guidelines in Germany .

Furthermore, roads can be categorized according to the type of usage restriction, for example for different types of traffic. The usage restriction is usually specified by corresponding laws or ordinances, in Germany and Austria by the road traffic regulations , in Switzerland by the road traffic law .

Design rules

The following parts of this section seem since 2013 is out of date to be : RIN defined categories, RAL replaced RAS-L / Q / K
Please help with to the missing information research and insert .

The division into street categories defines the so-called standard. These include, for example, the width of the lane or the design speed v _E . At the same time, it also defines which road construction guidelines apply to these roads. Roads of group A and categories BI and B II are planned according to the "Guidelines for the construction of roads" RAS-L , RAS-Q and RAS-K . The guidelines for the construction of motorways (RAA) have now been introduced for motorways . For the streets of the categories BIII, CI, C III, D II, D III and E III, the guidelines for the construction of city streets (RASt) apply . The guideline for the construction of rural roads (RAL) completes the new series of regulations and replaces the RAS series.

Road classes in the province of Schleswig-Holstein

The Schleswig-Holstein Provincial Parliament of the Prussian Province of Schleswig-Holstein adopted principles for the expansion and maintenance of the road network as early as 1879. The resolutions of the state parliament of December 12, 1879 and March 5, 1891 (published in the Official Journal 1891, p. 233 and Official Journal 1905) stipulated different widths, gradients and curve radii for the following road classes:

• Main country roads with a carriageway width of 6.0 to 7.0 meters for paved tracks and 5.0 to 6.0 meters for clinker tracks,
• Secondary roads with a lane width of 5.5 to 6.0 meters for paved tracks and 4.5 to 5.0 meters for clinker tracks,
• 1st class secondary roads with a lane width of 5.0 to 5.5 meters for paved tracks and 4.0 meters for clinker tracks,
• Second class secondary roads with a lane width of 2.5 to 5.0 meters for paved tracks and 2.5 to 4.0 meters for clinker tracks.
• Provincial roads were main and secondary roads which, after their expansion, had become part of the maintenance of the province.

Switzerland and Liechtenstein

Switzerland and Liechtenstein have the following classification:

• Classification according to the Road Traffic Act: Autobahn , autostrasse , main street , side street
• Classification according to the building contractor: see road system in Switzerland and Liechtenstein # Roads according to building load
• Classification by category (expansion standard): see road system in Switzerland and Liechtenstein # Roads according to expansion standard
