This dataset represents the 665 TAZs within Clark County that serve as the primary geographic unit of analysis in RTC’s regional travel demand forecasting model. They are used to spatially aggregate socioeconomic data related to land use and used as travel model inputs. TAZs also serve as the origins and destinations for travel in the region modeling framework. (Also available as KML.)
