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
#How to remove rows from transcad manual
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. 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.
