State of development
The development status (also quality ) of a traffic route, e.g. B. a street, describes the structural condition of an existing street or a new street. This includes the alignment , the road cross-section and the location of junctions . The development status of a route section depends on the traffic load, the historical development and the available financial resources of the road construction authority.
Systematics
There are four stages of expansion:
- A full extension describes the final extension of a road from the point of view of guidelines and regulations.
- The partial extension is approaching the full extension in stages, but still has the old extension standard in parts. This is often necessary if the expansion has to be carried out with traffic and the road cannot be completely closed. This method is often used on motorways.
- An intermediate extension represents an interim solution in which only the roadway is widened and the superstructure is reinforced. The lines are retained so that dangerous spots such as tight curves or junctions are not removed. This procedure is often used on congested federal and state roads.
- When the road surface is renewed, only the road surface is renewed without any further changes being made. The road cross-section is retained.
