To State DOTs and MPOs who will be delineating TAZs and TADs for the CTPP:


Many of you have been sending corrections to the TAZ contact databases over the last couple of weeks.  Thanks so much for your attention to this matter.  If you haven’t done so already, please convey your changes/updates to Ms Liang Long,


The Census Bureau Geography Division has told us that they are likely to use a data download system to transmit the TAZ delineation software and the county files to you.  This system will be password protected.    There will still be some agencies for which this approach may not be feasible, and in those cases, a mailout will be used instead.


Don’t forget the workshop on ACS data at TRB annual meeting, on Sunday,

January 23 at the Hilton, Columbia Hall 6 from 9:00 a.m. – noon.    Hope to

see you there.
