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:

Output	ASCII file	MDB table	Attribute file from attribute list
Aggregated data	-	-
Raw data	-	-	-

Show result attributes in attribute lists (Displaying result attributes in attribute lists)
Show result attributes in a result list (Showing result attributes in result lists)

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: Vehicle Network Performance Evaluation (Vehicle network performance : Displaying network performance results (vehicles) in result lists) Vehicle record (Saving vehicle record to a file or database) Vehicles in Network list (Displaying vehicles in the network in a list)
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
