This page is meant to document some of the undocumented questions relating to sidewalks and crossings and (hopefully) find some solutions.

Sidewalks

Use of `footway=sidewalk`

Should footway=sidewalk be used on every parrallel way to a road? How about cycleways? (Already partially discussed on Sidewalks)

Crossings

What is a crossing?

Is every interection of a sidewalk with a driveway a crossing? What should data consumers be expected to do with interections of sidewalks and driveways without highway=crossing?

Sidewalk intersecting a driveway.

Tactile Paving

Mappers can add tactile_paving=yes to indicate whether there is tactile paving at the crossing (tagged on the highway=crossing node 883 495 times as of 2022) Is there a way to tag the nodes saying the tactile paving continues across the whole crossing?

Tactile paving across the whole crossing.
Tactile paving on either end of the crossing

Talking Buttons

How to tag crossing "beg buttons" which will tell you information (possibly only when you hold the button down) such as the cross street or the travel direction?

Crossing information on the way

How much (if any) information should be duplicated between the highway=crossing node and the footway=crossing node? (Currently iD presets suggest duplication of the crossing=* information on the crossing way as well as the node.

Look left/right

How to tag markings which say "look left" or "look right" before the crossings

Warning of two way traffic
Look left warning

Traffic signs

Should traffic_sign=* be used on the crossing node to indicate the presence/absense of a traffic sign for the crossing? (Currently used 1 127 times as of 2022) Should a new key be invented? (e.g. crossing:traffic_sign=*) Should warning signs be included as well?

Pedestrian priority

How to tag whether a pedestrian has priority at a crossing? A "marked crosswalk" may indicate pedestian priority or it may only be cationary. crossing_ref=delineated describes a marked crossing without pedestian priority, but perhaps a new value of crossing=* (or perhaps a new crossing:priority=*) may be better and combine unmarked and marked unprioritized crossings, while using crossing:markings=* to tag the actual road markings.

How about handling the different priorities of diffenent crossers (i.e. pedestians have priority at a crossing, but cyclist must give way)?

Another example is unmarked crossings in Germany at intersections: Pedestrians must give way to cross traffic, but turning vehicles must give way to pedestrians. Should this even be tagged? What sort of defaults can we set per country (in much (all?) of the USA, any intersection of the road and a sidewalk is a "crosswalk", whether painted or not).

`footway=*` values for connections to crossings

Different users have discussed varous opinions regarding the footway=* value for the bit of footway between the kerb ramp and the sidewalk centerline. Some see it as an extention of the sidewalk (and thus footway=sidewalk, while others see it as an extension of the crossing (and thus footway=crossing).

Image	Discussion
Example for tagging as separate way
	Current tagging reccomendations at `footway=` (Tagging `footway=crossing` from sidewalk centerline to sidewalk centerline) Thick green ways: `highway=footway` + `footway=sidewalk` Thin green ways: `highway=footway` + `footway=crossing` Light blue nodes: `kerb=` Nodes with small traffic signals icon (missing yellow): `highway=crossing` + `crossing=traffic_signals` Node with large traffic signals icon: `highway=traffic_signals` + `crossing=no`
	Tagging recomendations of Berlin/Verkehrswende/Gehwege (Tagging `footway=crossing` from sidewalk centerline to sidewalk centerline) Sidewalk (`highway=footway` + `footway=sidewalk`) Crossing (`highway=footway` + `footway=crossing`) Crossing node (`highway=crossing` + `crossing=...`) Kerb (`barrier=kerb` + `kerb=*`).]]
	Only tagging `footway=crossing` kerb-to-kerb. (Prefered at Proposed_features/sidewalk_schema) Thick green ways: `highway=footway` + `footway=sidewalk` Black and white lines: `highway=footway` + `footway=crossing`
