WHAT IS A TRAFFIC ANALYSIS ZONE?
A Traffic Analysis Zone (TAZ) is a special area delineated by state and/or local transportation officials for tabulating traffic-related data. The boundaries typically follow physical features such as streets, rivers or canals and are updated as part of the decennial census. There are over 500 TAZs in Ada and Canyon Counties . TAZs vary in size from a few blocks to several square miles. The former are typically found in downtown areas, while the latter are more typical in rural areas. Nearly all metropolitan planning organizations such as COMPASS use TAZ geography to analyze future transportation needs.
