Description

A point where the flow of traffic is impacted by crossing aircraft. Aircraft crossings—while uncommon—are uniquely problematic for routing purposes.

Highways that cross runways may be closed for a considerable length of time to facilitate the safe landing of an aircraft. The impact to routing can be highly variable due to aircraft movements, making the calculation of an average delay to routing harder to quantify in comparison to other crossings. There are often unique restrictions placed upon vehicles crossing the highway (for security and safety purposes). They are most commonly controlled by boom gates, flashing lights, or airport/security staff, and all serve to prevent aircraft colliding with ground vehicles.

Ground Control traffic

[W] Ground operations traffic maneouvres on aeroways as a routine component of their regular duties. These vehicle movements are often coordinated via radio and traffic controllers, and tagging each point where these vehicles may interact with an aeroway would be unproductive. This tag should only be applied to ways which can be used by traffic other than routine ground operations.

Tagging

The tag is applied to a node on a suitable ground-based way in two situations:

Intersection of ground way and aeroway

Where a ground way and aeroway intersect, the tag should be added to a node that is shared by both the highway=*, railway=* (or similar), and an aeroway=taxiway, aeroway=runway, (or similarly trafficable aeroway feature).

On a ground way only

Where there is no suitable aeroway feature to share the node (for example, roads passing under an unmapped flight path), the tag should be to the highway=*, railway=* (or similar) at the approximate point where aircraft would "cross" the way.

Tags to use in combination

  • crossing=* can be used to specify the details of the crossing.

Aircraft Crossing Types

The relative position of the aircraft to ground traffic can nearly always be deduced by the connecting ways on the node. (ie: intersecting node=ground/node on ground-based way=overhead)

In some very rare cases it may be required to clarify the exact interaction between the aircraft and the ground-based way.

Tag Possible Values Comment
crossing:aircraft=* ground (default) Aircraft crosses way while on the ground
overhead Aircraft crosses way while airborne overhead at a low altitude
exclusion_only Aircraft does not directly cross the way, but the way is not navigable due to its movement nearby (ie, jet wash/unsafe clearance)
