Name: High Employment Density - Transportation Analysis Zones (TAZs)

Display Field: TAZ

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Transportation Analysis Zones (TAZs) are a generic geography type used in four step travel demand models to hold demographic data. This layer of TAZs was created for use in the Rhode Island Statewide Model (RISM), which uses Population, Household, and Jobs in an econometric model to predict travel across the transportation system. The full layer has many more fields than are included here; those fields were eliminated for clarity. The included fields relate to job density and trip production for the purposes of helping to prioritize project submissions to the Transportation Improvement Plan. The basic geography is composed of census block groups, which are aggregated in places where the RISM needs less detail and kept separate in places where more detail in needed. The current version of the layer was produced by VHB for the Division of Statewide Planning. For more details see Technical Paper 166. High Employment Density are any Census Tracts with 2013 Job Density(SqMi) >=1000.
