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. Access and egress is a specific form of the general concept of accessibility. 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:


Access and egress from a micro perspective

The physical point where you enter an urban object, such as a transport mode or building.


Access and egress from an urban perspective

Access and egress within the context of urban planning means the accessibility of a zone for a specific target group. For this accessibility architectural or infrastructural interventions are necessary, whether or not supported by legal arrangements. The roads serving this purpose are collectively known as an access route[2]. The level of accessibility determines the characterization of the access and egress road to a zone and forms an important aspect when developing evacuation management strategies.


Role of access and egress points in dealing with security events

Access and egress points are critical when dealing with an emergency or security event. In case of an emergency quick access and egress to and from the buildling are location are of vital importance. When planning evacuation routes access and egress points should be taken into account. Emergency access and egress points can be defined as[3]:

  • Emergency Access: Pertinent facilities and equipment remain available and unobstructed at all times to ensure effective security event detection, evacuation, suppression, and response.
  • Emergency Egress: A continuous and unobstructed way to travel from any point in a public building to a public way. A means of egress may include horizontal and vertical travel routes, including intervening rooms, doors, hallways, corridors, passageways, balconies, ramps, stairs, enclosures, lobbies, courts, and yards.

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.
