[CTPP] Re: Question from one of our pop staff

John: I would recommend you contact Mr. Phil Salopek or Ms. Clara Reschovsky at the Census Bureau (Population Division, Journey-to-Work & Migration Statistics Branch). Phil or Clara can look up the Metro Planning Organization contacts for the "Urban Element" contacts for New England areas. For the Boston MPO (Central Transportation Planning Staff) I would recommend talking to Marc Desmarais (their Census person) or Mr. Karl Quackenbush (Deputy Director at CTPS). I don't who's who in the other New England metro areas. All TAZes in the 1990 CTPP (Census Transportation Planning Package) AS WELL AS the 2000 CTPP are USER-DEFINED by the MPOs and STATE DOTs. I'm fairly certain there weren't rules that the TAZes nested on MCDs (it's nice if they were, but that's an issue for the local DOT or MPO to address! I can tell you that I nested my TAZes within Census Tracts, but NOT to PLACES....) Also, the CTPP/Urban Element CDs include a GIS layer (Caliper's TRANSVU format) of the TAZ, which can be overlaid on your MCD boundary layer. Your hotshot GIS analysts can then try to develop a correspondence between your places and the TAZes. I am crossposting my response to our "CTPP listserv" since that's where a lot of our MPO and Census Bureau colleagues "hang out" to discuss CTPP and Census Issues that are of interest to our MPO and Council of Governments communities. cheers, Chuck Purvis, MTC-Oakland CA *********************************************** Charles L.

Specifically, he would like to find out which TAZs are located within the boundaries of each MCD. He also needs to know if TAZs ever cross MCD boundaries in New England (e.g., like urbanized areas do). If so, to what level of geography do TAZs sum up to? Finally, are there any areas that are not covered by TAZs?
