- See Traffic calming on Wikipedia
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
