TransCAD Versions
TransCAD comes in two versions, Standard (or Full TransCAD) and Base TransCAD. Base TransCAD is built from the same software as Standard TransCAD. Base TransCAD has most of the GIS capabilities of TransCAD but many fewer procedures for transportation planning and analysis. Procedures included with both versions of TransCAD include network creation, shortest path calculations, network partitioning, and the creation of network bands (isochrones). Procedures not included with Base TransCAD are all of the travel demand forecasting and routing/logistics procedures. Planning utilities which permit importing of CTPP and PUMS files, import of TranPlan, MINUTP, emme/2, and TRIPS files are not included in Base TransCAD. There are some additional capabilities for public transit that are part of Standard TransCAD that are not in Base TransCAD. These include transit O-D estimation, shortest path based upon schedules, and traveler information functions. Lastly, Standard TransCAD has many advanced features for editing line layers that are not included in Maptitude or Base TransCAD. These include creation of interchanges and conflation of less accurate line layers to more accurate ones.
