Wow I've just discovered the world of TRANSIMS, a transport model with ambitious aims: "to model all aspects of human behaviour related to transport in one consistent simulation framework" (Nagel, 1999). I was sceptical at this claim at first, but further exploration has revealed that it is increasingly being adopted by Municipal Planning Organisations in the US, is completely open source (complete with a NASA license), and works on Linux as well as Windows.

All this is very exciting for someone researching modelling travel flows.

My question to the GIS community is has anyone got this to integrate with other OSGEO tools such as QGIS, PostGIS or PGrouter (although TRANSIMS has its own route planner)?

There is also a python-based visualiser for this software: http://sourceforge.net/projects/transimsstudio/?source=recommended

Hope this set of links is of use to others, and hope that people who've encountered TRANSIM can provide insight into its integration with GIS.

  • Since you're looking at transims, have you looked at urbansim.org ? – dassouki Mar 6 '13 at 19:22

This is a preliminary answer based on further research of and experience with agent-based transport models: use MATSim instead.

MATSim has a number of advantages over TRANSIM (Balmer et al. 2009), and has an inbuilt ability to interact with QGIS (MATSim Tutorial 2.1.4. Installing QGis).

I'm in the process of testing this software (so this answer may need to be updated), but preliminary results suggest that this answers my question to the T.

  • A short note: Nagel, that you quote on the 1999 paper, is also the main driving force behind MATSim. He started the work on MATSim after returning from the US to Europe, where he could not continue to work on TRANSIMS due to licensing reasons at that time. – cello Apr 25 '14 at 12:41
