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:

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
  • per link segment: the data is entered in the segments for all lanes
  • per lane segment: the data is entered in the segments for each lane

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
