To set Additional Parameters:

1. To specify the direction in which queuing Entities face, check the box labelled 'Change the orientation of Queuing Entities' and enter an integer into the 'Change to n degrees' box.
2. To set 'Navigation Properties', enter a number in the box labelled 'Distance Factor'.
   Note: The distance factor applies if the Drift Zone is a filtering object rather than a target object. Distance factors indicate how much more or less energy a person would use using an escalator or stairs compared to walking. Escalators have default factor of 0.2 (20% of the energy needed to walk on flat ground is required) and stairs have a default factor of 1.98 (almost twice as much effort needed compared to walking on flat ground).
3. If you would like your Entities to change their behaviour to respond to certain environmental conditions, you can set 'Entity Special Behaviour' parameters:
   Warning: Use behaviour modification options with caution. For example, the Alighting and Late boarding modifications make Entities highly motivated, which can lead to unreliable results if assigned incorrectly. In most cases the options should only be used to influence sub-sets of Entities within discrete areas of a model and where a model without the modification has shown anomalous behaviour.
   • None - no special behaviour is applied to Entities
   • Entity Step
     • Entity Priority
       • High - Entities have priority and are able to pass other Entities (with a lower priority) first.
       • Low - Opposite effect to 'High'.
       • Use where an 'after you' etiquette is helpful to resolve competition between opposing or allied Entities.
       • High and Low priorities can be used in combination to amplify the effect of each.
     • Direction
       • Left - Entities prefer to avoid other Entities and obstacles by stepping to the left.
       • Right - Entities prefer to avoid other Entities and obstacles by stepping to the right.
       • Use to help resolve high-density counter-flow inside constrained areas (stairs, passageways, footpaths and similar).
       • Also helps when modelling the effects of signage, floor markings, or local customs.
   Entity Environment
   • Vehicle (carriages, buses, lifts and other vehicles)
     • Alighting—Similar to 'High priority'; increases tolerance of Discomfort resulting from high-density and removes Entity synchronisation.
       • Use to help Entities leave a crowded space (lift, train carriage and similar).
     • Late boarding—By increasing tolerance of Discomfort and removing Entity synchronisation, this results in Entities being more willing to push into crowded areas (like a cramped train carriage).
       • Use to help Entities enter a crowded space (lift, train carriage and similar).
4. Click on the 'Entity Filter' tab and complete the filtering details (for further information, see Filtering ).
5. Click on the 'Availability' tab if you wish to set availability restrictions on the Drift Zone. See Setting Availability parameters .
6. Click OK to save the parameters.
