7 Simulation of Pedestrians
The following options are available:
● Individual Pedestrians: Each pedestrian is animated separately.
In 2D mode, pedestrians are displayed as colored, rounded boxes.
In 3D mode, they are represented by a 3D model from the model
distribution assigned to the pedestrian type.
- CONFIGURATION: If option Individual Pedestrians has been checked,
select the parameter to be displayed, enter the upper class limits to
set up the classes and assign a color to each class for display of
Speed or Acceleration of pedestrians in 2D display mode, cf. section
4.2.2.
- Interval defines that only every th frame of the visualization will
be updated. The default value is 1 and corresponds to a frame
update at every simulation time step.
● Aggregated values: If this option is active, each polygon (area, ramp,
stairway or grid cell respectively) is colored instead of display of
individual pedestrians. For that the CONFIGURATION settings are used.
- CONFIGURATION: Select the LOS scheme (or the parameter,
respectively) and define the appropriate color code. Alternatively, you
can select a parameter (Speed or Density) and set up user-defined
classes. For details, please refer to section 7.3.3.
- Update interval: Enter start and end of the interval for data updates.
The display changes every seconds, then shows
the result of the last (completed) interval and stays the same for
seconds (until the new result is displayed). The
update interval is also regarded for cumulative data display.
- Area-based: If this option is active, the walkable construction
elements (areas and ramps/stairs) are used for data collection and
graphical value display by color.
- Grid-based: If this option is active, a user-defined grid is created for
data collection and graphical value display by color that covers the
walkable elements. Enter the length of the edge of such a mesh to
define the cell size.
● No visualization: Neither individual pedestrians nor aggregated values
are displayed during the simulation. Use this option to maximize the
simulation speed.
Click CTRL+Q to activate the next of these three display options during a
simulation (Individual vehicles / Aggregated values / No visualization).
If option Aggregated values is selected in the [PEDESTRIANS] tab, press
CTRL+L to toggle between multiple LOS definitions. The LOS scheme
being currently used for data visualization is mentioned in the status bar.
