Traffic calming consists of engineering and other measures put in place on roads for slowing down or reducing motor-vehicle traffic as well as to improve safety for pedestrians and cyclists.
traffic_calming=* is used to tag various specific devices to achieve this, but some of methods used such as barrier=bollard blocking transit traffic are not tagged with this key. Some, like proper urban planning are subjective and not mapped at all in OpenStreetMap.
Note that traffic_calming=* is one of those tags where data consumers should expect multiple values being separated by semi-colon, for example choker;cushion. Usage of semicolons is minuscule with below 800 usages in mid April 2023, however, they are still used slightly more often than all of those conjoined values such as choked_island or choked_table combined.
How to map
Add one of the following tags to a highway way, or a highway node where the device is placed.
Common values
By causing vertical deviation
By causing lateral deviation
By causing both lateral and vertical deviation
Without causing neither lateral or vertical deviation
