Access and egress
Access and egress means the rate or means of entry or exit to an urban object, such as a transport mode or building. It includes footpaths, corridors, doorways, gates, steps etc., which may provide a means of access and egress, to be suitably constructed, kept free from obstruction and to be well maintained[1].
Different levels of access and egress points can be identified:
- Micro-level: the physical point where you enter an urban object, such as a transport mode or building.
- Urban-level: the locations where you can enter or leave a specific zone of the urban area, such as an access and egress road.
Access and egress points are important for reaction forces in reaching the security event location. Obstruction of an access or egress point impacts the flow of people or vehicles towards the desired location. This has an undesired, indirect effect on the duration and impact of a security event, but can also have a direct economic or social effect because specific locations are not available for public.
