Key:crossing_ref has traditionally been used to distinguish between Key:crossing types by their relationship to signals, signs, and markings using the British "animal" descriptions of them (zebra, pelican, puffin, etc.). The tag is intended to refer to a name that is commonly understood in the local region a crossing is mapped in, and other crossing classification descriptions have become more prevalent over time, including some which refer only to the crossing markings and do not imply anything about signalization. In many countries, the presence of markings on a crossing and the presence of pedestrian signals are not so closely linked that a description of a crosswalk type could accurately imply anything about its signalization. (For example, unmarked signalized crossings are common in the United States, and describing a crosswalk as "marked" or "unmarked" would commonly be understood as only referring to the presence or absence of markings.)

|crossing_ref=zebra||A zebra crossing is a controlled pedestrian crossing without traffic signals. Intermittent white stripes are painted across the carriageway at the crossing as well as Belisha beacons on either side of the road. Zig-Zag markings are used on approach and exits of the crossing. Pedestrians have priority over road traffic.
Where a zebra crossing crosses a cycle track, zig zag markings & Belisha beacons can be omitted, pedestrians have priority over cyclists.
|crossing_ref=tiger||A tiger crossing is a controlled pedestrian & cycle crossing without traffic signals. A zebra crossing is provided with an adjacent cycleway crossing directly parallel to it (marked by cycle symbols & large square markings on the edge). Belisha beacons and Zig Zag markings are provided the same as a Zebra Crossing. Both Pedestrians and Cyclists have priority of road traffic on the main carriageway.
In initial trials they were called Tiger crossings due to using yellow stripes instead of white, however become known as "Parallel crossings" in Law.
|crossing_ref=pelican||A pelican crossing is a traffic signal controlled pedestrian crossing. These are an older design of pedestrian crossing in the UK which only legacy installations still exist from pre-2004. They always feature far-side signals for pedestrians, with the near-side push button units (PBUs) displaying text lit up with "WAIT" when the button is pushed, along with instructions on how to use the crossing. Pelican crossings do not use sensors to detect when the crossing is clear of pedestrians, instead using a flashing amber light for road traffic when they need to give way to pedestrians crossing the road, or continue if there are no pedestrians crossing. Zig zag markings are always provided, except when the crossing is part of a junction.|
|crossing_ref=puffin||A puffin crossing is a traffic signal controlled pedestrian crossing. These are the newer types of pedestrian crossing in the UK. They have additional sensors which can detect when pedestrians are waiting to cross, and to see when they are on the crossing, making the crossing safer and more efficient.
They usually have near-side signals shown on the side traffic first approaches from, making pedestrians look at traffic instead of across, this also means that pedestrians will not see the light change to red whilst they are on the crossing. Some puffin installations (mostly in London) still use far-side signals at busy crossings where it may not be easy for all pedestrians to see a near-side indicator. Zig zag markings are always provided, except when the crossing is part of a junction.
|crossing_ref=toucan||A toucan crossing is a traffic signal controlled pedestrian & bicycle crossing. These are a variation of pelican OR puffin installations which allow bicycles to cross as well as pedestrians. Newer installations will have near-side indicators (like puffin), while some older installations will have far-side (like pelican). On Near-side units they display both a red or green bicycle alongside a red or green pedestrian, while on far-side they will only show a green bicycle. Zig zag markings are always provided, except when the crossing is part of a junction.|
|crossing_ref=pegasus||A pegasus crossing is a traffic signal controlled horse crossing. These are a variation of pelican OR puffin installations which allow horse rider (either mounted or dismounted) to crossing. Like toucan crossings these can have either near side or far side signals, but Pegasus crossings are not combined with pedestrians or bicycles, which means they will also show a red or green horse. Pegasus crossings usually have a Toucan provided adjacent to them for pedestrians and cyclists to use. Zig zag markings are always provided, except when the crossing is part of a junction.|
There are several MUTCD-compliant crosswalk marking styles:
- crossing_ref=standard – the most common in the U.S.
Some other MUTCD-compliant crosswalk configurations involve more than a marking style, for example a certain kind of signal. These configurations have also been tagged using crossing_ref=*, preempting information about the marking style:
- crossing_ref=hawk – HAWK beacon
- crossing_ref=pedestrian_scramble – pedestrian scramble with explicit markings and signals; alternatively crossing:scramble=yes
As of 2021, highway=crossing crossing_ref=hawk is the most commonly used tag for a HAWK beacon, a relatively new kind of crossing in the United States that uses standard road markings and pedestrian signals but a unique signal directed at motorists. 
- Key:road_marking (Note that this tagging scheme, which is considered experimental, does not document a way to describe the marking style of a footway=crossing crosswalk line.)
