AequilibraE Project

This page is dedicated to a practical implementation of the AequilibraE project. In case you are interested in better understanding its structure, please visit its documentation webpage.

Under the project tab, there are some options to choose from and the following sections explore some of these actions.

Open & Close project

These options are pretty straightforward and are used either to open or close a project. You just have to click Project > Open project to open a project, and Project > Close project to close it.

Keep in mind that to open another project or to create a new one, you must close the currently open project, otherwise AequilibraE is going to return an error.

Create example

AequilibraE has three different example sets one can use as learning tool, and they were all made available within the QGIS ecosystem.

Within Project > Create example, select one of the available models, the desired location of the output folder, and just press Create. The window will close automatically and you can open the project folder in the Project tab.

Parameters

The parameters file is part of the AequilibraE package for Python, so all the reference documentation for this section can be found in its documentation page.

The QGIS plugin, however, has a nice interface to view and edit the parameters file, which can be accessed through Project > Parameters. This interface, depicted below, allows one to edit and validate parameters before submitting them as the new parameter file for all AequilibraE procedures.

Log file

The log file contains information about which actions took place and when they happened. For example, after you create a project from OSM, if you access the log file, you are going to see something like the figure below, containing the sequence of steps followed to import the OSM network. If you wish to access this file later on, it is also possible to save this log file locally in your machine, using the save to disk button in the lower left corner of the log file box.

Run procedures

The run procedures allows you to define model entry points and their default arguments, and run models to the model itself. Usage at QAequilibraE is pretty straightforward: select one of the available functions, click on the Run! button, and wait for the log file to open with the output results of the model.

To better understand the application of the run module, we encourage you to read about it at the AequilibraE documentation.
