Lane-status encoding

How the DATEX II MDM Baustellen lane-status strings work, and every key in the standard field and the extension.

How the encoding works

A lane-status string describes a road’s carriageway cross-section, read left to right, one character per element. It is case-sensitive. The same alphabet is used by the standard field laneStatusCoded and the richer extendedLaneStatusCoded, so one renderer handles both.

2 is the central reservation (median): it splits the oncoming carriageway on the left (lanes u/i, drawn as down arrows) from the direction of travel on the right (lanes o/e, drawn as up arrows). 1 is a temporary single-carriageway divider.
Lane cells are boxes: a green arrow = open, a blue arrow = narrowed, a green double arrow = reversible (w), a red cross = closed (x), a yellow box = hard shoulder present (s).
l/r are hard-shoulder separation lines; L/R are the heavier carriageway↔special-lane separators.
The sign codes (f F g G p P H) render as official StVO traffic signs.
Any character outside the alphabet renders as a boxed ?.

Standard — `laneStatusCoded`

Documented in the Mobilithek “Datenmodell für Baustellen Version 04-00-00 – 05|2017” (mobilithek.info/help/download).

Extension — `extendedLaneStatusCoded`

There is no public documentation for this field; it is in use in Mobilithek publications by several German federal states.

With thanks to Martin Phillip Ullmann of the LBV.SH for providing the documentation of the extended encoding.

The sign glyphs are official German StVO traffic signs from Wikimedia Commons, all in the public domain (PD-VzKat / PD-GermanGov / PD-Vz historisch), so no attribution is legally required — the per-sign sources are listed here for transparency.
