Bollard

Mooring bollards, such as this one in the Hudson River, were the first type of bollard. The use of the term has since expanded.

A bollard is a sturdy, short, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats. In modern usage, it also refers to posts installed to control road traffic and posts designed to prevent automotive vehicles from colliding or crashing into pedestrians and structures.
