I have completed TAZ updates for all 8 Counties in the Indianapolis Metro Area using
TransCAD 3.5 District Manager Phase 2 Utilities developed by the Caliper Corp. Significant
time saving was achieved through tagging atomized polygons.
Attached is a copy of procedures used in Indianapolis. It has been expanded to cover joint
operations of coding statewide zones in addition to MPO zones. It also touches on how to
code statewide zones in non-MPO Counties.
