Key:traffic_calming

+/- traffic_calming Description To tag road features that are designed to slow down traffic in residential areas. Group Highway Element help Used combinations in World Australia/Oceania Europe (list) Asia (list) Central America (list) South America (list) Africa (list)

The traffic_calming=* tag can be used to identify roads or points along a road with speed bumps or other devices to slow motorised traffic.

How to Map

Add one of the following to either a length of highway=* or to a node along the highway:

List of common values:

• traffic_calming=yes: General / unspecified traffic calming device
• traffic_calming=bump: Short bump - length (in direction of travel) about 30 cm or shorter. Spans the entire width of the road, but can have cuts and small gaps left and right for cyclists. (see speed bump)
• traffic_calming=chicane (not to be confused with barrier=chicane): Hazards on the street you have to drive round (see chicane)
• traffic_calming=choker: Narrowed road, sometimes signed as pinch points
• traffic_calming=cushion: A hump with spaces between or several multiple rectangular humps aligned across the road. This allows emergency vehicles, buses (due to their wider axle) and bicycles to pass through without slowing down. (see speed cushion)
• traffic_calming=hump: Similar to a bump, but longer - total length usually 2-4 m (in direction of travel) (see speed hump)
• traffic_calming=island: An island is a small area that temporarily separates two different directions of traffic. See also crossing=island for islands intended for pedestrians crossing the road.
• traffic_calming=rumble_strip: Multiple very low bumps (few cm at most) spaced few meters apart spanning the entire width of the road. Does not limit speeds as such, but are very noticeable to the driver as they generate noise and shake the car mildly. Not to be confused with the similar device used to alert drivers when they drift from their lane. (see rumble strips)
• traffic_calming=table: Designed as a long speed hump with a flat section in the middle. The flat section is long enough for all wheels of a passenger car to fit on that section simultaneously. Does not slow as much as a hump and is usually used on roads with residential speed limit. (see speed table).
