A generic crossing with no traffic signals of any type, just road markings; e.g., zebra-crossings. Which means mostly used in combination[1] with highway=crossing (and crossing_ref=zebra) as mentioned in an approved proposal[2]. Despite the name, this tag is not for uncontrolled crossings: for unsignalized, unmarked crossings, use crossing=unmarked.

It is also used for pedestrian level crossing without barrier or light signal. It maybe indicated by a St. Andrew's cross.

This tag is also used for pedestrian crossings of tramway crossing.

When used as a railway level crossing, if the railroad crossing has barriers add crossing:barrier=yes instead.

If the railroad crossing has a warning light add crossing:light=yes instead.

For pedestrian crossings on a street, there is another proposed scheme available which seems to be more specific. The used tags are:

  • crossing=marked - A generic crossing with no traffic-signals of any type, just road markings
  • crossing=unmarked - A crossing without road markings or traffic lights

Terminology

uncontrolled is a misnomer in the context of pedestrian and bicycle crossings along roadways. In reality, "uncontrolled crossing" is a legal term or traffic engineering jargon that varies in meaning by region but never carries the same semantics documented above:

  • In the United Kingdom, an uncontrolled crossing by definition has a pedestrian island (traffic_calming=island) and may or may not have road markings.[3][4]
  • In most of the United States, an uncontrolled crossing at an intersection of two roads may or may not have road markings, but an uncontrolled crossing mid-block is required have either road markings or traffic signs, or else it is not a crossing at all.[5][6][7] In some states, such as California, an uncontrolled crossing may or may not have road markings. An uncontrolled crossing is implied at any intersection where one is not visibly marked or signposted, even if it would be a very unsafe place to cross.[8]

Data consumers should be aware that this tag may have been used on a variety of crossing types and avoid making strict assumptions when encountering it. The crossing=marked/unmarked tagging scheme is intended to resolve this discrepancy in conjunction with crossing:signals=*.

How to map

Set a node node on the junction where the transition is and add

at the highway
at the railway
by the tram

Tags to use in combination

  • bicycle=yes/no - Access permission for cyclists
  • tactile_paving=yes/no - Indicate if a specific place can be detected or followed with a blindman's stick
  • wheelchair=* - Indicate if a special place can be used with wheelchairs

Editor preset

There is an implementation of a JOSM preset, which is using tags highway=crossing + crossing=uncontrolled + crossing_ref=zebra for a zebra-crossing (crosswalk) object.
