An arm barrier (boom gate, boom barrier) is a bar, or pole pivoted (rotates upwards to open) in such a way as to allow the bar to block vehicular access through a controlled point. Combine with access=* where appropriate.
Note that "lift gate", term used in OSM tagging is not used in actual English.
How to map
Tag a node with barrier=lift_gate. A tiny proportion of cases (0.01%) tag a way instead.

Access
If no access tags are provided, generally motor_vehicle=private would be assumed. Since pedestrian and cycling access is generally physically possible for the majority of boom barriers, many mappers imply foot=yes + bicycle=yes; however, the access may be restricted or obstructed by other means. As can be seen from the examples below, a multitude of situations is possible, so explicit tagging of access is recommended.
|
Boom barrier that intentionally provides no obstacle for pedestrians and cyclists. Generally used to control access to territories with private parking but otherwise free access.
|
|
Boom barrier that doesn't restrict access for pedestrians or cyclists, but neither provides a means to cycle past it without dismounting. |
|
Boom barrier with folding parts physically preventing pedestrian access when closed. Similar barrier when opened |
|
Boom barrier which is physically surmountable by pedestrians, but anybody attempting that would likely be halted by guards from the adjacent amenity=security_booth.

Boom barrier Boom barrier before a movable bridge that is open to traffic most of the time, but closed when the bridge is moved to allow a ship to pass.
