Traffic Analysis Zones (TAZs)

Delineation of TAZs for 2015 Regional Travel Demand Model

Traffic Analysis Zones (TAZs) are created by referencing spatial and demographic features within the Metropolitan Planning Area. The size of the zones vary, but in general the more populated an area is with residents and employment the smaller the zone, while sparsely populated areas have larger zones.

Other factors in delineating TAZs:

  • Geographic Features
  • Bodies of Water / Terrain
  • Boundaries
  • Census Blocks, Parcels

BFCG Staff worked closely with regional planners in defining TAZs. The 2015 version of the model includes a large increase of TAZs created that will allow for more reliable outputs and detailed travel behavior information.
