Pl:Crossings

Tramwaj na przejściu pieszym w Tallinie.

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	footway=crossing
Footway	Railway	railway=crossing	footway=crossing
Cycleway	Bridleway, path, road, or track	highway=crossing	cycleway=crossing
Cycleway	Railway	railway=crossing	cycleway=crossing
Bridleway	Footway, cycleway, path, road, or track	highway=crossing	?
Bridleway	Railway	railway=crossing	?
Path	Road or track	highway=crossing	path=crossing
Path	Railway	railway=crossing	path=crossing
Road or track	Railway	railway=level_crossing	N/A
Highway	Aeroway	aeroway=aircraft_crossing	N/A
Railway	Aeroway	aeroway=aircraft_crossing railway=level_crossing	N/A

There are ongoing proposals for other kinds of crossings:

• An area representation of a pedestrian crossing

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. 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. 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.

Some schemes are able to express more common configurations of crossings than others:

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.

• 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
