2009 TIGER/Line Shapefiles released today; info on 2010,TIGER/LineShapefiles

by Ed Christopher

FYI--Besides the 2009 Tiger Files it looks like we will have the new 2010 Files before the 2010 Block population counts come out in around March of 2011. This is good news. Just yesterday I was in a meeting where the question came up. ================== The Census Bureau has released 2009 TIGER/Line Shapefiles today. Available here: http://www.census.gov/geo/www/tiger/ This will be the last public release of TIGER data until early 2011. This early 2011 release will include all of the updated 2010 tabulation geography that serves as the geographic framework for 2010 Census data tabulations (including the new 2010 Census tracts, block groups, blocks, voting districts, and much more). Around the same time as this 2011 geospatial data release, Census will be releasing the tabular data with 2010 Census population counts down to the Census block level. See the attached document for more information, including changes under consideration and a request for input. -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 4749 Lincoln Mall Drive, Suite 600 Matteson, IL 60443

Data Source Question

by Sabula, Julianne Ruth (Engineering-Const Planner II)

I am passing on a question from one of our strategic planners. "Where can I find data on Mode of transportation for work trips by county, travel time to work by county, number of commuters by community/city, and carpool commuter activity by community/city?" If anyone knows where to find this information (state of Utah), please let me know. Thank you!

Synthetic Data for PUMA using 2005-2007 ACS

by Liang Long

On February 23, Joseph Sakshaug, a Ph.D. Candidate from University of Michigan, gave a presentation at the Census Bureau on data synthesis for small geographic areas. Joe?s research is motivated by the increasing demand for microdata for small geographic areas with simultaneous increase in restrictions of data release at small geography due to the risk of disclosure. While Joe?s research is not focused on transportation data, his research is likely useful to our needs for the CTPP using ACS records. His research utilized county-level data from the 2005-2007 American Community Survey (ACS) and applied it to PUMA geography. He applied a Hierarchical Bayesian model to simulate the synthetic values while accounting for homogeneity within each geographical unit at the PUMA level. Joe tested many variables, including household income, age etc. In his validation the synthetic data were very close to the actual surveys with respect to distributions and means. Joe indicated that the method can be extended to smaller geographic areas such as census tract and block groups. The Westat team working on the NCHRP 08-79 project "Producing Transportation Data Products from the American Community Survey that Comply with Disclosure Rules" also attended the meeting. Joe can be reached by joesaks(a)umich.edu if you want to get more information about his research. Thanks!

My go-to document is Polzin's "Public Transit in America": http://144.171.11.107/Main/Blurbs/Public_Transit_in_America_Results_from_th… I dont' remember the table number, but he compares JTW and NHTS in detail.

Aggregating Census TAZs

by Tom Krenzke

Has anyone tried aggregating Census TAZs for the nation into something larger (e.g., 20K in population) that still makes sense for transportation planning (e.g., corridors, MIS, Districts, planning areas etc.)? Or do you have an algorithm that combines TAZs? If you do, would you have a correspondence file to share with us, and the purpose for which this aggregation was made? Thanks, --Tom Krenzke Westat

Journal of Transport and Land Use Vol. 2 No. 3 published

by Elaine.Murakami＠dot.gov

The CTPP community may be interested in this journal since the focus is on commuting and spatial structures. The paper by Patuelli uses administrative records (similar to LEHD OTM). The paper by Verhetsel is 31 mg, so my machine was unhappy trying to save it (and I was impatient). My apologies for duplicate postings.
