bolard

A bollard is a sturdy post or column, typically made of metal, concrete, or stone, used to direct traffic, prevent access, or secure areas. They are commonly found in urban environments, along sidewalks, in parking lots, and at the entrances to buildings or restricted zones. Bollards serve a variety of purposes, including pedestrian safety, traffic calming, and asset protection.

In traffic management, bollards can be installed in a row to create a barrier, preventing vehicles from entering pedestrian areas or driving onto sidewalks. They can also be used to delineate parking spaces or guide the flow of traffic in congested areas. Removable or retractable bollards offer flexibility, allowing for controlled access when needed, such as for emergency vehicles or maintenance crews.

Beyond traffic control, bollards are frequently employed to protect buildings and infrastructure from accidental or intentional impact. Their robust construction can withstand significant force, acting as a physical deterrent against vehicle ramming attacks. In some applications, bollards are integrated with lighting to enhance visibility and aesthetics, contributing to the overall urban design and safety of public spaces. The design and material of bollards can vary widely depending on their intended function and the surrounding environment.
