Performing evaluations

Depending on the network objects used, various data is produced during simulations, e.g. information on vehicles, links, areas, nodes, traffic jams, green time distribution or PT waiting times (Overview of evaluations). This may be raw data or aggregated data. Depending on the type of data and the desired further use, you can show evaluations in lists and/or windows and save them to text files and/or database files. To do so, select the desired evaluations before the start of the simulation and configure them.

Note: Some output options and individual evaluation results may only be available with add-on modules. You need a license to use the add-on modules.

If you wish to display the result data of evaluations in a database, you must configure the database connection (Configuring the database connection for evaluations), (Saving evaluations in databases).

Tip: You can also show simulation data in diagrams (Creating charts).

1.  Define basic settings for the management of the result data: overwrite previous results, configure columns, file or database as location of automatic saving, define percentiles (Managing results).

2.  From the Evaluation menu, choose the desired entry:

  • Configuration: Opens the Evaluation Configuration window with the following tabs that allow you to make basic settings for result data management and evaluations:
  • Evaluation output directory box: By default, the path to the evaluation output directory, the directory to which the currently opened network file *.inpx is saved. If you are using Scenario Management and a scenario has been opened, you can view the path to the directory in which the scenario is saved.
  • Result Management tab: Under Result Management, make the basic settings for managing result data before you configure Result Attributes or the Direct Output and start the simulation.
  • Result Attributes tab: Select evaluations which you wish to display in attribute lists or result lists (Configuring evaluations of the result attributes for lists)
  • Direct Output tab: Select evaluations which you wish to save to a file or database (Configuring evaluations for direct output)

3.  Confirm with OK.

4.  If you have configured evaluations and wish to create result data from a simulation, start the simulation (Running a simulation).

The evaluations are generated and, depending on your settings in the selected program elements, they can be shown or saved to files or databases.

5.  If you have configured evaluations for network objects, whose results can be displayed in windows or result lists, from the Evaluation menu, select the entry of your choice:

Notes:  

  • By default, the currently selected units for distances, speeds, accelerations, decelerations are taken into account for the evaluation (Selecting network settings for units). You can also choose the unit for attribute values in the attribute selection list in the Format column (Selecting attributes and subattributes for columns of a list).
  • Some attributes use different units. These are specified in the evaluation.
  • If the script files change attributes that are used in evaluations, the changed values are saved to the evaluations.
