The guidelines for the construction of motorways ( RAA for short ) are a technical set of rules that is valid in Germany and that was introduced with the General Circular Road Construction ARS 7/2009. They describe the planning and design of motorways and are a result of the work of the Research Association for Roads and Transport . The current and first version is the 2008 edition.

predecessor

The RAA replace the following regulations for the part of the motorways and urban motorways:

  • RAS-L , edition 1995/1999 - Guidelines for the construction of roads, part: Routing
  • RAS-Q , Edition 1996 - Guidelines for the construction of roads, part: Cross sections
  • RAL-K-2 , edition 1976, corrected reprint 1991 - guidelines for the construction of country roads, part: junctions, section 2: plan-free junctions
  • AH-RAL-K-2, 1993 edition - Current information on the design of non-plan nodes outside built-up areas (supplements to RAL-K-2)
  • RAS-K-2-B, 1995 edition - Design guidelines for plan-free junctions on streets of category group B (supplements to RAL-K-2)

Standard cross-sections

Design class 1 (long-distance motorway / supraregional motorway)

RQ 43.5 (width of the paved area is 2 × 18.25 meters)

Standard cross-section for new eight-lane motorway routes to be built. Use from 100,000 vehicles per day.

RQ43,5.svg
RQ 36 (width of the paved area is 2 × 14.5 meters)

Two-lane, six-lane motorway for heavily used motorway sections. Suitable for the range between 60,000 and 100,000 vehicles per day and a high proportion of trucks.

RQ36.svg
RQ 31 (width of the paved area is 2 × 12 meters)

Standard cross-section for motorways with four lanes. Capacity up to 70,000 vehicles per day.

RQ31.svg

Design class 2 (motorway-like road)

RQ 28 (width of the paved area is 2 × 10.5 meters)

Standard cross-section for motorway-like roads. Capacity up to 30,000 vehicles per day. With higher forecast traffic volumes , a 4 + 0 traffic routing in workplaces is necessary, then standard cross-sections of design class 1 should be used.

Design class 3 (city motorway)

RQ 38.5 (width of the paved area is 2 × 16.5 meters)
RQ 31.5 (width of the paved area is 2 × 13 meters)
RQ 25 (width of the paved area is 2 × 9.75 meters)
