Drift Zones
Drift Zones provide information about the nature of a space and people’s movement through it, such as the level of the terrain and any necessary changes of direction or changes in walking speed. In some circumstances, notably long corridors, they may be more appropriate to use than Focal Drift Zones. They are useful as a supplementary routing measure in areas of high congestion or anomalous situations where Entity movement needs to be ‘corrected’ from that created by LEGION Auto-navigation.
Drift Zones have an area, a directional arrow and can filter by Entity Type and Target. They are generally used for modelling the following:
- Long narrow corridors, generally for corridors of 2m width or less.
- Stairs and escalators in rare occasions when the specialised Stair and Escalator objects are not sufficient.
- Boarding areas in front of ‘ad-hoc’ stairs and escalators when the specialised Stair and Escalator objects are not sufficient.
Drift Zones are also useful in the following cases:
