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.

Dear Colleagues (apologies for cross-posting for those who also subscribe to TMIP-L),
The study team for NCHRP 8-79 (Developing Transportation Data Products from the American Community Survey That Comply With Disclosure Rules) is looking for small and medium-sized MPOs to participate in the second phase of research into the impact of disclosure-avoidance techniques on the resulting data usability for transportation planning and travel demand modeling of the 5-year ACS-based CTPP tabulations. The team is interested both in small and medium-sized MPOs who maintain their own travel demand forecasting models, and MPOs who perform sketch-planning modeling using the methods from NCHRP Report 365. Participation would include production of a nominal amount of travel model output.
Please contact me off-list at rroisman(a)vhb.com<mailto:email@example.com> if you represent a small or medium-sized MPO and would like to assist the research effort, or know of some good candidate agencies. Thank you for your time.

To: Subject: Survey on Transportation and Land Use Modeling Tools
I am pursuing a PhD in the School of Public Policy at George Mason
University where I am currently finishing my dissertation work. The
topic of my dissertation is how simplified integrated transportation and
land use modeling tools can be used to support transportation and land
use planning. As part of my research, I put together a survey to better
assess what role integrated transportation and land use modeling (ITLUM)
tools can play in the metropolitan planning decision-making process.
Recent surveys indicate that many states, jurisdictions, and
metropolitan planning organizations are looking at implementing ITLUM
tools. However, there are a number of ITLUM tools available to
practitioners ranging from simple sketch planning tools to complex
microscopic simulation tools. There are benefits and limitations to
using any type of ITLUM tool. Selecting a specific tool to use is often
a tradeoff among many different factors. The purpose of this survey is
to gather expert opinion on the use and application of ITLUM tools as it
relates to the metropolitan planning decision-making process.
You can access the survey here: https://vovici.com/wsb.dll/s/54c9g4817b.
Please complete the survey by January 11, 2011.
If you could forward this survey to your colleagues I would appreciate
it. I am trying to get as diverse a response rate as possible. I believe
the topic of my research will be of interest to SCOP members and I look
forward to sharing the results of my research with you.

Re: INVITATION to a Webcast on the Use of Archive Data for Planning
and Operations Performance Measures sponsored by the I-95 Corridor Coalition
Learn how outsourced probe data is being used for performance measures and
planning at various levels - national, regional, and specific MPOs.
The Travel Information Services Program Track (TISPTC) is inviting you to
participate in a webcast titled "The Use of Archive Data for Planning and
Operations Performance Measures" on Thursday, December 2, 2010 from 1:00 PM
to 2:30 PM (EST).
Shawn Turner (Texas Transportation Institute) - Use of Private Sector Speed
Data for Historical Performance Monitoring: Lessons Learned from National
and State-Level Analyses. His presentation will include lessons learned
through TTI's three most recent projects/applications: 2010 Urban Mobility
Report (to be released in early December 2010); Texas DOT's 100 Most
Congested Roadway Segments; and, Minnesota DOT's Pilot Project for Statewide
Reporting. Shawn will also discuss key insights that will help public
agency staff more easily procure and use private sector speed data in their
agency's planning and performance monitoring processes.
Michael Pack (University of Maryland CATT Lab) - I-95 Corridor Coalition
Vehicle Probe Project (VPP) Dashboard & Data Download Tool. Michael will
explain this tool that was developed for North Carolina's VPP Performance
Measures project and incorporates incident data through RITIS (Regional
Integrated Transportation Information System) with real-time and archived
data and provides access to raw data for report development beyond scope of
this application. Michael will also review the data that is being collected
and the performance measures that can be calculated.
Andrew Meese (Metropolitan Washington Council of Governments) - Use of the
Vehicle Probe Project data for Congestion Management Process Support. More
specifically, Andrew will review MWCOG's efforts regarding their use of the
VPP data in the Congestion Management Process (CMP), speed validation in
travel forecasting models, and speed distribution for air quality modeling.
Andrew will also discuss the advantages and caveats and the potential future
uses of the Vehicle Probe Project data by his agency.
If you plan to participate in this webcast, please RSVP to
nhrebien(a)kmjinc.com (or Natalia Hrebien at 610.228.0207) by Monday, November
29, 2010 and she will register you for the webcast and forward to you the
conference call information and webcast link.
Should you have any questions in the meantime, please contact Bill Stoeckert
at 774.207.0367 or Karen Jehanian at 610.228.0211.
We look forward to your participation!
While you are still waiting for the CTPP full data release with the
access software (scheduled on December, 2010), don't forget FHWA
prepared and released the county-to-county and place-to-place flow
tables prior to full data's formal release. The flow tables are for
Total Workers and for 18 categories of Workers by Means of
Transportation. County level data also included CTPP 2000 data but
categorized only by 8 transportation modes. We have NOT included the
CTPP2000 for Place-to-Place data files because of difficulties in
matching FIPS codes for Places between 2000 and the current CTPP. These
two files are published in CS FTP sites:
Also, transportation profiles using ACS 2005-2007 and CTPP2000, which
give people a quick transportation snapshot of their areas are also
published at AASHTO CTPP website.

The Census Bureau released the 2009 ACS (1 year) data in late September.
This is the first time that sub-county (Place) totals were added to the
weighting procedure. Therefore, you may see some large differences
between 2008 and 2009 ACS 1-year results, based on this new method.
(The previous weighting method was restricted to county level data.)
I attended the Washington State Data Center meeting on Nov 5, and the CB
reported that there were large differences in Detroit and Omaha, for
We have previously reported that the lack of sub-county estimates was
problematic for some cities. Please see our CTPP profile sheets using
2005-2007 ACS http://ctpp.transportation.org/Pages/profiles.aspx
where we recommended that you might want to use independent city totals
as controls. So, we hope that that use of sub-county controls will help
the ACS in the long run, but in the short run, it is probably not a good
idea to make a year-to-year comparisons with 2008 and 2009 ACS 1-year
In general, my recommendation is to use 3-year ACS tabulations when
possible, because of the increased number of unweighted survey
Other news: The CTPP (using 2006-2008 ACS) will be going into software
beta-test this week. This round of CTPP, with more than 200 tables,
will use a web-based data access system. The tabulations are
restricted to geographic units with more than 20,000 residential
Selected home-to-work flow tables (county-to-county and place-to-place)
are available on the Cambridge Systematics ftp site:

If I understand it correctly, the TAZ system being created by MPOs for submittal to the Census Bureau will be used to obtain the 'CTPP-like' product being paid for through AASHTO. As far as the ACS tabulations are concerned, we will still only have existing Census geography, e.g. county, MCD, tract. TAZs will NOT be part of that geography.
My question is, "Am I correct in this assumption?"
