I compared my Hodgepodge model to TransCAD and it was pretty close however, mine was 10 times as slow due to me doing it all in python and not in an organized way. Use the calibration and validation every step of the way.for nodes, you'll need U_turns allowed?, left_penalty, right penalty, average_Delay, accepted delay, green_cycle_time_per_leg.link ID, link name, speed, length, number of lanes, capacity per lane, total capacity, and directionality.For turning restrictions and travel behaviour on specific links and nodes, make sure to incorporate those as fields in your GIS layer, here's what you'll need per link row:.Build a QGIS plugin for trip assignment, that is based on at least Stochastic, all or nothing, and equilibrium.IF you're using logit modelling or Bayes, then you can do something with R or WinBugs. For Mode Choice, it depends on the algorithm you're using.With steps 1 to 4, you can generate, trip production, attraction, their balancing, and Trip Distribution.this is just on top of step 3 to handle all your statistical needs forecasts and backcasts Build an R or MS Excel model that handles all your socio economic forecasting.The goal here is to be able to develop a table of the following sort: TAZ_001_HBW, HBNW, HBS, NHB, etc, for both attractions and productions for each zones Build a QGIS ITE plugin to determine highway trip generation and production rates - or - build your own trip generation data.

Build a QGIS Highway Capacity Manual plugin that analyzes levels of services on highway to determine Capacity -or- use best practices that are acceptable for the jurisdiction you're modeling.It is better if you can have those as event based data on top of your existing GIS layer IT also should be able to create and output origin/destination tables. This plugin should also be able to create your centroids and connect them to your existing links via your Traffic Analysis Zone (TAZ) ids. Build a QGIS routing plugin, or you can use osm2po, or postgis/pgrouting directly.

Although, I can't share the code with you, I can tell you what I did: On the other hand, I have developed 3 or 4 travel demand models based on QGIS. UrbanSim is an open source agent based modelling solution but as far as I recall it doesn't handle transportation networks.

The closest you can get are some micro modelling solutions like Transims or matsim that I find lacking of a lot of needed data, methodologies, tools, or network handling that are available in commercial software.

Some other stackexchange posts mentioned that the FreeARC utility may succeed in extracting an ARC file where nomarch fails, but their download links seem to be dead.The short answer is that there isn't one especially if you're looking for a TransCAD or Emme/2 alternative as there is no open source package that comes close to those.

Here is my first attempt at trying to understand what this file is: $ file AM.mtx Unfortunately I didn't see any occurrences of the strings 'matrix' or 'mtx'. I tried to search for TransCAD file formats and came across this page: I could use TransCAD directly to convert this to another format, but I'd like to be able to do this in an automated way via a shell script. I would prefer to do this at the Unix command line. I have what I believe to be a TransCAD matrix file called data.mtx which I would like to be able to convert to some other file formats. Having necessarily created a roadway network, TransCAD allows the establishment of specific trajectories over the link layout, termed route systems, intended for the operation of special transportation modes on fixed paths.
