What it is Filled
A short sturdy post, originally a mooring post on a quay or ship for securing ropes, and now also a post set in streets, pavements and squares to control or prevent vehicle access, protect pedestrians and buildings, and mark boundaries, in fixed, removable, rising and impact-resistant forms; bollards are elements of street furniture, port infrastructure and security design and are governed by standards for visibility, spacing and impact.
Why it exists Filled
Let an agent explain bollards and their kinds and uses in mooring and streets, describe design standards and accessibility considerations, support selection and placement questions, and describe history.
Distinguishing features Filled
- Point obstacle
- Mooring or access control
- Fixed or movable
- Standardised
What robots and AI may and may not do Filled
Must not
- Present a bollard as impact-rated without certification.
- Advise placing bollards that block wheelchair users or trap visually impaired people.
- Operate rising bollards without authority or while people are near.
- Confuse mooring and street bollards.
Only with a human decision
- Approving hostile vehicle protection for a public space.
May
- Explain mooring and street bollards and their uses.
- Describe accessibility considerations such as contrast and spacing.
- Support choosing bollard types for a stated purpose.
Moral aspects Filled
- Bollards protect pedestrians from vehicles; poor ratings give false security.
- Badly placed bollards hurt blind and disabled people.
Who is affected
- Pedestrians
- Disabled people
- Drivers
Owners Filled
Steward
The highway authority or property owner who installs it; the port authority for mooring bollards.
