#Using transcad to utd modeling full
Some are just beginning, some have full running models. TransCAD Users There are many states in America that currently use TransCAD Many states in America are using TransCAD. Why are agencies converting their travel models to TransCAD?Ħ Why Convert? Some widely-used older modeling software are no longer being supported – a new modeling platform is required Limited capabilities in Graphics Memory GIS Network size Number of TAZsħ There are many states in America that currently use TransCAD Why Model?
