Showing data from links in lists
Using the Link evaluation, you can record the result attributes of vehicles based on segments or lanes of links and connectors for the defined time interval. You can restrict the evaluation to vehicle classes and individual vehicles. The following must be defined in the network:
- Links (Modeling links for vehicles and pedestrians)
- Connectors (Modeling connectors)
- Vehicle inputs (Modeling vehicle inputs for private transportation)
|
Note: Ensure that the attribute Link evaluation of links and connectors - which you want to evaluate - is selected (Attributes of links). |
If you assign links a color based on aggregated parameters, for the Links evaluation, select Collect data (Assigning a color to links based on aggregated parameters).
by default, the data for all vehicle classes is entered together. You can also show the data for certain vehicle classes separately in the evaluation (Configuring evaluations of the result attributes for lists).
You can save the following data and data formats:

1. From the Evaluation menu, choose > Configuration > Result Attributes tab.
2. In the Links row, select the option Collect data.
3. If desired, change the time and/or the interval (Configuring evaluations of the result attributes for lists).
4. Click the More button.
The Links window opens.
5. Make the desired changes:
Element | Description |
---|---|
Collect link results |
|
6. Confirm with OK.
7. Start the simulation (Running a simulation).
Result of evaluation of links
- From the Evaluation menu, choose > Result Lists > Link Segment Results.
A link evaluation contains the following data:
Attribute |
Definition |
---|---|
Volume |
Volume [veh/h] In mesoscopic simulation, for link segments outside the sections of microscopic simulation, the average number of vehicles is displayed that have entered and exited the sections on the meso edge. |
Density |
Vehicle density |
Speed |
Average speed |
Emissions |
For add-on module API package only: Results of emission calculation for selected file EmissionModel.dll (Activating emission calculation and emission model for a vehicle type). Emission values are also displayed in:
|
SimRun |
Simulation run: Number of simulation run |
LinkEvalSegs |
Link evaluation segment: Number of link evaluation segment |
DelayRel |
Delay (relative): Total delay divided by total travel time of all vehicles in this link segment during this time interval |
TimeInt |
Time Interval: Duration of the evaluation intervals during which the data is aggregated |
You can also show the following attributes of the Cartesian world coordinates in the list as indirect attributes of link evaluation segments:
Attribute |
Definition |
---|---|
StartCoord |
Start coordinates: coordinates (x), (y), (z) at which the link evaluation segment begins |
StartCoordX |
Start coordinate (x): x value of the start coordinate |
StartCoordY |
Start coordinate (y): y value of the start coordinate |
StartCoordZ |
Start coordinate (z): z value of the start coordinate |
EndCoord |
End coordinates: coordinates (x), (y), (z) at which the link evaluation segment ends |
EndCoordX |
End coordinate (x): x value of the end coordinate |
EndCoordY |
End coordinate (y): y value of the end coordinate |
EndCoordZ |
End coordinate (z): z value of the end coordinate |
Link |
Number of the link on which the link evaluation segment is located |
StartPos |
Start position: Position in meters at which the link evaluation segment on the link begins |
EndPos |
End position: Position in meters at which the link evaluation segment on the link ends |
