Sub: StatewideTazs The statewide component of the CTPP will have the county and place/MCD as default geographic reporting units, just as in the 1990 CTPP. We have discussed including tracts as a possibility to be added, but have not decided on including it as a geographic reporting unit in the CTPP data structure as a default. A county can have TAZs defined by only one entity (the State DOT or the MPO) in the present stage because TIGER allows only one geographic layer. However, we are in the process of setting up a system where State DOTs can, at a later stage, go in and define State TAZs in the metropolitan areas for their statewide modeling. These State TAZs will be used for CTPP 2000, but will not be included in TIGER. This effort will succeed the TAZ-UP and Work-Up effort and will take place in 2001. Nanda Srinivasan
