A choker is a narrowed point along a road, generally reducing traffic to a single lane, deliberately designed to slow down or discourage motor vehicle traffic. Chokers can also be called 'pinch points' or 'slow points'.

How to map

This can be mapped as a node on a highway=* way. Optionally, the length of the choker can be mapped by splitting the highway=* way and adding traffic_calming=choker to the section of the way where the choker is located.

A choker can be used in combination with a pedestrian crossing.

Other traffic calming features can be used with a choker, such as a speed cushion. You can specify this like: traffic_calming=choker;cushion

Tags used in combination

  • priority=* -Specifies whether one direction of traffic has priority over another side which needs to give way (yield). If no direction has priority, leave this key blank.
  • bicycle_bypass=* - Specifies if there is a bypass of the choker for bicycles on one or more sides. For information in correct usage, refer to the wiki page.
  • maxspeed:advisory=* - Specifies if there is an advisory maximum speed for the choker
  • maxwidth=* (or more rarely width=*) - Maximum width of vehicle that can pass through it
