About Data Profiles

Data Profiles are discrete sets of data that are used in LEGION to simulate various factors crucial to accurate modelling. The following Data Profiles are available within LEGION Model Builder:

  • Population Profile – a profile used with Populated Zones and Evacuation Zones. Specifies the number and type of a zone's initial population and the destinations of Entities leaving a zone.
  • Arrival Profile – a profile used with Entrances. Used to model the arrival of pedestrians into a model over time.
  • Availability Profile – a profile used with all Spatial Objects except Entrances, Gates, Populated Zones and Evacuation Zones. Required to specify when an object is available for use or not, within a simulation. They can also be used with CAD Layers to turn CAD on and off at certain times in a simulation.
  • Delay Profile – a profile used with Delay Points and Gates. Used to model one or more delays that apply over a period of time.
  • Event Profile – a profile used with a Direction Modifier. Enables you to select a specific number of Entities to respond to events at specific times.
  • Exit Profile – a profile used with Exits. Used to control the rate of egress of pedestrians from a model.
  • Gate Control Profile – a profile used with Gates. Used to control whether a Gate is set to operate in one of these states: In, Out, Free In, Free Out, Free Both, Closed.
  • Passenger Distribution Profile – a histogram indicating preferred distribution of passengers along a Platform or inside a Train. Only works with the Platform and Service objects. A default Uniform Distribution profile is added to all new models.
  • Speed Profile – a profile containing preferred walking speeds for use with Entity Types.
  • Size Profile - Entity – a profile (histogram or distribution) that specifies the physical area occupied by Entities, within an Entity Type.
  • Size Profile - Luggage – a profile (histogram or distribution) that specifies the physical area of luggage, to be added to luggage-carrying Entities’ areas, within an Entity Type.

Arrival Profiles and Event Profiles are time-function histograms used by LEGION models to specify the arrival of Entities through Entrances and the number of Entities affected by Direction Modifiers, respectively.

Data Profiles can be created within LEGION Model Builder, using the Edit Data Profile dialog box, or they can be set up in the Data Template spreadsheet and imported using the Data Import Manager. To learn about the Data Template spreadsheet, see The Data Template Spreadsheet.

Creating Exit Profiles, Delay Profiles and Availability Profiles, using the Edit Data Profile dialog box, is described in relation to the Spatial Objects they are used with. See Spatial Objects In Detail. Speed, Size and Luggage Size profiles are described in relation to Entity Types (see CAD Layers and Availability Profiles).

A Note on Availability Profiles

Availability Profiles enable you to turn most Spatial Objects on or off at specified times and for specified periods within the runtime of a simulation. The objects that are not affected by availability are Entrances, Populated Zones and Evacuation Zones. They can also be applied to CAD Layers to simulate the arrival and departure of trains and other vehicles (see CAD Layers and Availability Profiles).

Availability Profiles can be created with the Data Template spreadsheet, or set up manually using the Edit Data Profile dialog box. They are like Arrival Profiles, but the graph specifies when one or more objects are available (On) and unavailable (Off).

Relevant objects have a parameter tab labelled Availability, where users may specify that the object uses the time scope of a particular Availability Profile. Availability Profiles can also be used in conjunction with conditions to make them sensitive to operational schemes, or events like emergencies or evacuations. A condition can be entered on the tab labelled Conditions.

For Direction Modifiers users can specify either an Event Profile or an Availability Profile in their Scope Profile. When using an Event Profile, the number of pedestrians specified in the profile each time step, are affected by the Direction Modifier, assuming that many are in it. When using an Availability Profile set to On, all Entities within the Direction Modifier will be affected, whatever their number.
