Status: de factoPage for proposal

This tag describes a pedestrian crossing that is marked but not controlled by traffic lights or people.

The type of marking can still be described explicitly with crossing_ref=*

Another common way to map such crossings is to use crossing=zebra (only if the markings are zebra markings) or crossing=uncontrolled.

How to map

Set a node node on the highway where the transition is and add highway=crossing + crossing=marked.

If the crossing is also mapped as a way way, tag it as highway=footway footway=crossing crossing=marked or highway=cycleway cycleway=crossing crossing=marked as appropriate.

Tags to use in combination

  • tactile_paving=yes/no - Indicates whether a blind or visually impaired pedestrian can detect or follow the feature using a cane
  • crossing:island=yes/no - Specifies whether a pedestrian crossing has a refuge island
  • crossing_ref=* - Used to reference a specific type of crossing markings
  • crossing_ref=zebra - A crossing with zebra markings
  • bicycle=yes/no - if the crossing is expressly also to be used by cyclists
  • lit=yes/no - Indicates whether a feature is lit.
  • kerb=* - Used to indicate height and thus accessibility of a kerb
  • crossing:markings=* - The existence and style of pedestrian crossing markings
  • wheelchair=* - Indicate if a special place can be used with wheelchairs

Software support

Editors

Starting from v2.12.0, released Dec 2018, iD described crossing=zebra as "outdated" and encouraged users to switch to crossing=marked + highway=crossing. This has attracted controversy.

This change was reverted in v2.17.0, released Dec 2019, due to ambiguity issues raised by mappers.[1]

Renderers

OsmAnd draws gray and white stripes along the crossing way and adds a pedestrian pictogram at the crossing node.

Straßenraumkarte Neukölln reserves a parking-free buffer zone around the crossing that is smaller than for crossing=zebra or crossing=traffic_signals. [1]

Routers

OpenSidewalks converts crossing=uncontrolled and crossing=zebra to crossing=marked. [2]

MOTIS Per Pedes Routing indicates whether the crossing is marked [3][4][5] and can calculate a detour that avoids unmarked, unsignalized crossings. [6]

Tagging schemes and tag growth evolution

Graphs of different schemes are shown on the following page link:
📈 http://taghistory.raifer.tech/#***/crossing_ref/zebra&***/crossing/zebra&***/crossing/marked&***/crossing/uncontrolled&***/crossing/traffic_signals

The amount of objects increased exponential after implementation of a iD preset end of 2018 via v2.12.[2]

The growth of the amount of objects stopped immediately after implementation an update of iD preset end of 2022 via id-tagging-schema v5.10, see chart above (green line).[3]
