Assigning a color to links based on aggregated parameters
During a simulation, you can display traffic-related parameters classified by color based on link segments. For these traffic-related parameters, you can select result attributes of the current simulation, e.g. volume, density, emissions or delay time (relative). For visualization of the data, you can define colors or select color schemes that have been predefined, e.g. for volume, density, emissions or delay time (relative). Thus you can easily differentiate the vehicular parameters on the individual links during the simulation in the network, for example, to quickly locate a hotspot in a large network.
You can make similar settings for pedestrians in areas (Using LOS schemes for showing aggregated pedestrian values).
At the same time, you can also display the vehicles in the simulation in color based on their attributes or simulation data (Assigning a color to vehicles based on an attribute), (Dynamically assigning a color to vehicles during the simulation).
The Drawing order 3D attribute of display types also affects links whose display is based on the Use color scheme graphic parameter, since a display type is assigned to each link.
1. Before starting the simulation, from the Evaluation menu, choose > Configuration > Result Attributes tab > Links and make the following settings:
2. Select Collect data.
3. Into the From time and To time boxes, enter the simulation seconds during which you want to collect data for a classified display.
4. Into the Interval box, enter the length of the time intervals for which you to aggregate data.
5. Click the More button.
6. Select how you want the data to be collected:
- per lane segment: separately for each lanes
- per link segment: for all lanes together
7. On the network object sidebar, next to Links, click the Edit graphic parameters button .
The list with the graphic parameters of the network object type opens (List of graphic parameters for network objects).
8. In the Drawing mode list box, click Use color scheme.
9. In the list of graphic parameters, click Color scheme configuration.
The Edit Color Scheme for Links window opens.
If the window does not open because the option has been deactivated since program start, click the icon at the end of the row to open the window.
Under Classification based on, Lanes or Segments is selected. This depends on the option per lane segment or per link segment of the configuration of the evaluation for links (Showing data from links in lists).
10. In the Classification based on section, select > Segments. Lanes have static attributes only.
11. Make the desired changes:
Symbol | Element | Description |
---|---|---|
Attribute |
Opens an attribute selection window. The result attributes can be filtered (Setting a filter for selection of subattributes displayed). |
|
Predefined color scheme |
Select pre-defined color scheme list box: Select a defined color scheme and show it in the list below. The color schemes vary in color and class bound:
|
Element | Description |
---|---|
List |
The unit of the values depends on the attribute selected and is displayed in the Classification section, below the attribute selected. |

12. If you want to change the RGB values in the Color column, double-click the desired row.
13. Confirm with OK.
