−	A bollard is an item of street furniture comprising a vertical post fixed into the ground at intervals to prevent vehicle access or to keep vehicles from using the pavement. Bollards can be up to a 1m high but are usually ~~much~~ shorter. The intervals between bollards usually allow the passage of pedestrians, prams ~~and~~ cyclists. They can also be used as traffic calming measures to narrow the available space for vehicles to pass through, thereby slowing them down.	+	A bollard is an item of street furniture comprising a vertical post fixed into the ground at intervals to prevent vehicle access or to keep vehicles from using the pavement.
