Bollards are a common design of vehicle security barriers (VSB) that are required in certain locations to mitigate criminal or terrorist vehicle-borne threats. Bollard type VSBs provide a solution that resolves many common operational issues faced at busy transport interchanges.
Observational surveys and research studies have been carried out under normal travel conditions to assess whether permanent bollards schemes affect pedestrian movement or give rise to additional health and safety concerns.
Studies of evacuation scenarios have not been carried out.
This traffic advisory leaflet (TAL) outlines the findings of these studies and provides guidance to inform the planning and design of bollard schemes installed for the purpose of hostile vehicle mitigation.
Guidance revised November 2016 for the release of Influence of bollards on pedestrian evacuation flow (TAL 01/16).
