An update on AequilibraE

Posted Posted in AequilibraE, GIS, Python

A few of my readers have noticed my absence on this blog and the seemingly slow development of AequilibraE, so I decided to share what is going on and what the plans are for the next 6 months. The current version of AequilibraE (0.3.5.x) is the most powerful and robust version of AequilibraE yet, with […]

AequilibraE’s new release

Posted Posted in AequilibraE, Uncategorized

It has been quite a while since I last released a version of AequilibraE, but a new one just hit the QGIS repository. The long time between releases was initially due to an attempt to include select link analysis in the assignment, but a LOT happened in the meantime, and although this version still does […]

Scenario comparison

Just like it happened for the stacked bandwidth tool, I got a “ feature request” from colleagues at work for a scenario comparison tool, much in the style available in every single commercial software available out there. However, as QGIS allows for the creation of stacked bandwidths, it was natural to create something a little […]

Stacked bandwidths

This dynamic has two nice components. The first one is that some pretty […]

AequilibraE Linux support and desire lines

The last few weeks have been quite busy for me, with a quick trip to the US, a short and sweet conference in New Zealand and the costumary TRB paper reviewing and committee business coordination. However, I got to finish two new features of AequilibraE. Desire lines (including the Delaunay lines I proposed about two […]

New version of AequilibraE

I realize now that it has been well over a year since my last post, but I think I have a few good reasons: I moved to Australia (our hearts are still in the US, but we are living down under now) I completely re-factored AequilibraE, and it is now a much more robust and […]

Introducing AequilibraE for QGIS

Posted Posted in AequilibraE, GIS, Python

Back in January 2003 when I started my career in transportation planning as an intern at Logit, my main tools as far as software went were MS Excel and TransCad (sometimes Maptitude).  I would do all the modeling in Excel/VBA and use Transcad for assignment and visualization, and would always rely heavily on the visualization […]
