Setting Focal Drift Zone parameters

As with all Spatial Objects, you need to set the parameters of the FDZs you have placed. This is best done as a ‘group edit’.

To set FDZ parameters:

  1. Select all the FDZs you need to edit in the Object Directory (they will be on a Partition Layer).
  2. Select Edit Properties.

    The ‘Edit Multiple Focal Drift Zones’ dialog box is displayed.

  3. If you require your FDZs to only affect those Entities navigating towards their focal segments, check the box labelled 'Filter by entities navigating through the associated focal segment'. This can be important if you have FDZs close together and want to ensure they only affect the desired Entities.
  4. Click on the Filters tab and complete filtering details (see Specifying filter settings for full instructions). If you checked the box mentioned in the previous step, you may not need to specify any further filters here.
  5. If you want to link a Focal Drift Zone to an Availability Profile, click on the ‘Availability’ tab.
  6. Select an Availability Profile from the drop-down list labelled ‘Time Scope’. If you don’t want to apply conditions, proceed to step 10.
  7. If you want to apply conditions to the Availability Profile, check the box labelled ‘use condition’.
  8. Select an option from the left-hand drop-down list:
    • AND– the condition will apply only when the ‘Time scope’ settings and the conditional settings are both ‘true’.
    • OR – the condition will apply when either the ‘Time scope’ settings or the conditional settings are ‘true’.
  9. Set up your condition as described from step 4 of "To set up a Condition:" in Restrictions .
  10. If you wish to apply any restrictions to the condition, click on the ‘Availability’ tab again and enter values for the following restrictions (details in Restrictions ):
    • Time before action
    • Minimum activity period
    • Maximum activity period
    • Minimum time between Actions
  11. Click OK to save the parameters.
