Placing an Individual Focal Drift Zone
This procedure describes how to place a single FDZ. You will not need to do this very often but may find it useful to resolve problems with tricky geometry in the model or with spatial conflicts encountered by the other partitioning methods. You may also use Focal Drift Zones with focal segments to improve navigation of very large crowds around corners, or to create ‘fanning-in’ or ‘fanning-out’ effects near bottlenecks.
To place an individual Focal Drift Zone:
-
Click on
or select
.
-
Click in the model where you would like to place the FDZ’s focal
target.
The shape of a suggested FDZ is indicated by brown dotted lines. You can move these lines by moving your cursor, which will also move the focus.
- To accept the suggested shape press <Enter> and go to step 6. To reject the suggestion and draw the shape manually, type n and press Enter.
- Drag and draw the shape of the FDZ manually; press <Enter> to place it.
- You are prompted to decide if you want to add a Focal Segment. Press <Enter> to add one, or type n and press <Enter> to place the FDZ without a Focal Segment and go to the last step.
- If you chose to place a Focal Segment, follow the steps described in Placing a Focal Segment .
- Set the FDZ’s parameters as described in Setting Focal Drift Zone parameters.
