Frequently Asked Questions

• What is a Traffic Analysis Zone (TAZ)?
  • TAZs are the units of the geographic boundary system used by the PSRC to run and report results from its Travel Demand Forecast Model. The TAZs nest within a larger Forecast Analysis Zone (FAZ) geographic boundary system, with each FAZ containing between 1 and 20 TAZs. TAZ boundaries generally, with few exceptions, also line up with census tract boundaries, with each census tract containing between 1 to 9 TAZs. There are a total of 938 TAZs in the region.
