Pl:Crossings
crossing służy do oznaczenia skrzyżowaniem pomiędzy dwoma różnymi ciągami komunikacyjnymi przeznaczony dla różnych rodzajów transportu, potencjalnie wymagające zatrzymania się w celu przepuszczenia innego ruchu.
Terminologia
W Polsce pod pojęciem crossing rozumiemy przejście dla pieszych zarówno takie wyraźnie oznaczone znakiem drogowym D-6 lub pionowym P-1-, jak i takie które nie ma oznaczeń.
Podstawowe wymagane tagi
Podstawowe oznaczenia przejścia dla pieszych:
| Jeśli droga … | Przekracza … | Przecięcie oznaczamy tagiem | Tag na linii |

| Footway | Cycleway, bridleway, path, road, or track | highway=crossing[1] | footway=crossing[2] |
| Footway | Railway | railway=crossing[3] | footway=crossing |
| Cycleway | Bridleway, path, road, or track | highway=crossing | cycleway=crossing[2] |
| Cycleway | Railway | railway=crossing[3] | cycleway=crossing |
| Bridleway | Footway, cycleway, path, road, or track | highway=crossing | ?
|
| Bridleway | Railway | railway=crossing[3] | ?

There are ongoing proposals for other kinds of crossings:

Street crossings
Street crossings are classified by the presence of traffic control devices regulating the movement of traffic at the crossing. Tags for classifying crossings have historically grown organically, but there were two formal attempts at standardizing the tags. All of these tagging schemes are in widespread use in OpenStreetMap but have incompatible semantics:
- By 2008, the predominant tagging scheme set crossing=* to a set of mostly animal nicknames corresponding to specific types of pedestrian crossings in the United Kingdom and some Commonwealth countries. These tags made no provision for crossing types found in other countries. In some cases, mappers have diluted the meaning of these terms to cover other configurations.
- A 2008 proposal moved the zoo animals to a separate crossing_ref=* key and uses crossing=* to indicate the degree of traffic control, making some UK-centric assumptions about which kinds of traffic control devices go together. This scheme differed significantly from preexisting usage, due to concerns about the eccentric UK terminology.[5] Despite being approved in a relatively small vote, it was ignored by many mappers, who continued to use the crossing=*-only scheme.
- A 2018 proposal, which was expanded the following year, streamlines crossing=* to indicate only whether the crossing is marked, relegating signalization to an orthogonal crossing:signals=* key, by analogy with the subkeys used at railroad crossings. It also resolved misleading terminology associated with the 2008 proposal.
Popular editors have implemented a mix of these schemes, often incompletely.[6] Mappers in some regions prefer one scheme over another. As of June 2022, relatively few renderers and routers are known to make any distinctions based on these tags.[7]
Some schemes are able to express more common configurations of crossings than others:
| Road markings | Pedestrian signals | Cyclist signals | Equestrian signals | UK-centric ad-hoc usage | approved 2008 proposal | 2018/2019 proposal |
|---|---|---|---|---|---|---|
| tak | tak | tak | nie | crossing=toucan | crossing=traffic_signals crossing_ref=toucan bicycle=yes |
crossing=marked crossing:signals=yes bicycle=designated |
| tak | tak | nie | tak | N/A | crossing=traffic_signals crossing_ref=pegasus horse=yes |
crossing=marked crossing:signals=yes horse=designated |
| tak | tak | nie | nie | crossing=pelican | crossing=traffic_signals crossing_ref=pelican[8] |
crossing=marked crossing:signals=yes |
| tak | nie | nie | nie | crossing=zebra[9] | crossing=uncontrolled crossing_ref=zebra |
crossing=marked |
| nie | tak | nie | nie | N/A | N/A | crossing=unmarked crossing:signals=yes |
| nie | nie | nie | nie | N/A | crossing=unmarked[10] | crossing=unmarked |

Railroad crossings use subkeys of crossing=* to indicate the presence of certain warning devices:
- crossing:barrier=* for boom gates
- crossing:bell=* for an audible tone, such as from a bell
- crossing:light=* for flashing crossing signals
- crossing:saltire=* for a crossbuck
An uncontrolled railroad crossing – that is, one lacking any of these warning devices – is sometimes tagged level_crossing=uncontrolled. Formerly, level_crossing=* paralleled the 2008 proposal for street crossing classification; however, most of its values are now deprecated.
Inne oznaczenia
- crossing=no – indicates the absence of a crossing where one would otherwise be implied by highway geometry
- ford=yes – indicates the location of a ford, where a non-waterway crosses a waterway
- hazard=animal_crossing – indicates an area where animals are known to cross the road, creating a collision hazard
- man_made=wildlife_crossing – not a crossing in the sense of conflicting traffic, but rather a kind of grade separation

- ↑ Footway–cycleway intersections in some regions, such as the Netherlands, are not considered crossings because of local right-of-way rules.

- ↑ Originally, the value zebra entailed a specific pattern that in the UK is only found at unsignalized crossings, never at signalized crossings. However, in colloquial usage elsewhere, it has come to mean any kind of road marking.
- ↑ crossing=unmarked was not included in the original 2008 proposal, but it was approved for unmarked crossings as part of a 2011 proposal about sidewalks. It became popular for unmarked, unsignalized crossings as part of a crossing=traffic_signals/uncontrolled/unmarked tagging scheme. The 2018 proposal for crossing=marked reaffirmed the broader, approved definition of crossing=unmarked that also applies to unmarked, signalized crossings.
