It's just as bad to not make a plan as to blindly follow the one you
already have.

To: Subject: Survey on Transportation and Land Use Modeling Tools
Hello
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.
Thank you.
--Matt

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:
ftp://ftp.camsys.com/temp/outgoing/CTPP/New%20CTPP%20ACS/
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.
http://factfinder.census.gov/servlet/DatasetMainPageServlet?_program=ACS
&_submenuId=&_lang=en&_ts=
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
example.
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
results.
In general, my recommendation is to use 3-year ACS tabulations when
possible, because of the increased number of unweighted survey
responses.
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
population.
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?"

Video and Tutorial Help Data Users Prepare
for Launch of Census Bureau's New American FactFinder
In January 2011, the U.S. Census Bureau plans to launch a revamped
version of its data delivery tool, American FactFinder. The new American
FactFinder offers a new look, new tools and easier access to Census
Bureau information. In order to prepare users for this change, the
Census Bureau has prepared an online video, the American FactFinder
Virtual Tour, and a tutorial to demonstrate the enhanced features and
functions of the new and improved FactFinder.
It is important for users to become familiar with accessing data from
the new FactFinder in time for the release of 2010 Census data starting
next year. The American FactFinder will be the primary tool used to
access all 2010 Census data. It will also give users access to other key
data sets such as the American Community Survey, economic census and
other programs.
In addition to the video, a tutorial, "American FactFinder Quick Start,"
specifically demonstrates how to conduct a basic text search, view
search results and select a data product to view. Additional tutorials
on other new FactFinder functions, such as creating a map, transposing
rows and columns, and performing topic searches, will be available in
the near future.
To access the video and tutorial, visit American FactFinder at
http://factfinder.census.gov/home/saff/aff2.html.

Hi All,
The Census Bureau released a collection of brief reports based on the 2009 ACS, including one that focuses on commuting by public transportation in 2008 and 2009. See the following link:

Hi Everyone:
I posted a link to the FR notice on August 24. (a copy of that post is
at the bottom of this message)
The CB proposed criteria are best evaluated at the local level, as the
impacts will vary widely, based on how much the jump criteria influenced
the existing urbanized areas, population growth and decline over the
last decade, and the proximity to other urbanized areas and urban
clusters.
As a starting point, people might want to review the existing UAs by
using HEPGIS.
http://hepgis.fhwa.dot.gov/hepgis_v2/UrbanBoundaries/Map.aspx
This GIS was created by Bruce Spear, and is now maintained by Supin
Yoder at FHWA. The link above takes you to the part showing the Census
urbanized areas (50k+) and urban clusters (below 50k). It also includes
an approximation of MPO planning areas.
You can use the "info" button and click on specific areas, and the
Census 2000 population for that area will be shown in a box below the
map (you might have to scroll down to see it). You can use American
FactFinder to see an ESTIMATED population for the existing urbanized
areas (current boundaries).
http://factfinder.census.gov/servlet/DatasetMainPageServlet?_program=ACS
&_submenuId=&_lang=en&_ts=
By using the 2005-2007 (3-year) ACS you will have more geographic areas
included. Again, this ACS estimate does NOT have the results of the 2010
Census incorporated into it.
HEPGIS does NOT have the 2010 Census population counts that will be used
by the Census Bureau to define the new urbanized areas, however, you
will be able to review areas that the CB is expecting to fall into an
"agglomeration" (see pages 52180 and 52181 in the FR notice).
I (Elaine) checked a couple a "potential agglomerations" and they looked
like they were either already touching, or very close to touching, so it
would make sense to combine the areas, especially if the entire region
experienced population growth in the last decade. Combining some of
these areas could result in a total urbanized population exceeding
200,000 (current threshold for TMA), but at least in one case that I
checked, one of the two urbanized areas in the potential agglomeration
was already over the TMA threshold.
At previous sessions on this topic, the question of whether FHWA would
force MPOs to combine, the answer was "no, there are existing cases of
multiple MPOs in one urbanized area."
http://ctpp.transportation.org/Documents/UA%20Q-A.pdf
For the Jump criteria to shift from 2.5 miles to 1.5 miles. This could
potentially reduce some urban areas to below 50,000 or 200,000
population. But, without the benefit of the 2010 Census block data,
guessing at specific cases is impossible.
Hope this information is helpful to you.

------COPY of Elaine's post to the CTPP listserv on August 24, 2010---
The Federal Register notice from the Census Bureau is now posted.
The due date for comments is November 22.
You may want to listen to Mike Ratcliffe's web presentation from June
11, 2010 that is available at:
http://ctpp.transportation.org/Pages/webinardirectory.aspx
The Census Bureau announces publication of the "Proposed Urban Area
Criteria for the 2010 Census" in the Federal Register of August 24,
2010, available on the Federal Register's website at
http://www.gpoaccess.gov/fr/
The Census Bureau is seeking public
comment on these proposed criteria. Comments, suggestions, or
recommendations regarding the criteria should be submitted in writing,
no later than November 22, 2010, to Timothy Trainor, Chief, Geography
Division, U.S. Census Bureau, Washington, DC 20233-7400.
The Census Bureau's urban-rural classification is fundamentally a
delineation of geographical areas, identifying individual urbanized
areas of 50,000 or more people and urban clusters of at least 2,500 and
less than 50,000 people; "rural" encompasses all population and
territory not included in urban areas. The Census Bureau's urban areas
represent densely developed territory, and encompass residential,
commercial, and other non-residential urban land uses. Additional
information about the Census Bureau's urban-rural classification is
available on the Census Bureau's website at
http://www.census.gov/geo/www/ua/urbanruralclass.html
The proposed urban area criteria for the 2010 Census as well as
summaries of the proposed changes, are available on the Census Bureau's
website at http://www.census.gov/geo/www/ua/2010urbanruralclass.html
Changes proposed for the 2010 Census include:
* Use of census tracts as analysis units in the initial phase of
delineation
* Potential return to a maximum jump distance of 1.5 miles (the
distance was increased to 2.5 miles in the Census 2000 criteria).
* Use of land use/land cover data to identify territory containing
non-residential urban land uses or land cover that restricts urban
development, such as marshland and wetlands.
* Lowering the minimum number of enplanements (departing passengers)
from 10,000 to 2,500 to qualify airports for inclusion in urban
areas.
* Elimination of the central place concept.
* Requirement that, in addition to at least 2,500 total population,
an area must contain at least 1,500 persons residing outside
institutional group quarters to qualify as urban.
* Splitting urban agglomerations of 1,000,000 or more population
Based on metropolitan statistical area boundaries, or, in New England,
along metropolitan New England city and town area boundaries.
(Note: the FR notice on pages 52180 and 52181 includes potential urban
agglomerations)
For further information about the Census Bureau urban-rural
classification, or the proposed criteria for the 2010 Census, please
contact Vincent Osier, Chief, Geographic Standards and Criteria Branch,
Geography Division, U.S. Census Bureau, via e-mail at
vincent.osier(a)census.gov or telephone at 301-763-9039.
1. Jane Traynham of the Maryland State Data Center shared their
work using the new CTPP 3-year data. Please see the bar charts that
show changes in county-to-county commute flows.
http://planning.maryland.gov/msdc/S1_Census.shtml
2. Nathan Erlbaum of the New York State DOT has created tables
that show the county-to-county flows, using CTPP2000, LEHD 2006, and
CTPP 2006-2008.
https://www.nysdot.gov/divisions/policy-and-strategy/darb/dai-unit/ttss/
cttp_acs
Because of the very large population in New York City, the 5 boroughs
are treated as counties. If you look at the "internal" county flows for
Kings, Queens, and New York, you will see major differences between the
LEHD and the Census 2000 and CTPP 2006-2008 numbers, and if you ignore
the numbers and use % distributions, you will see large differences as
well. Nathan's web page lists many of the reasons for these
differences, including differences in the worker population, survey vs.
administrative records, etc.
3. The CTPP2000 in .ivt format (including the Beyond 20/20
software) are now available in the BTS TranStats as downloadable files.
http://www.transtats.bts.gov/Tables.asp?DB_ID=645&DB_Name=Census%20Trans

yond%2020/20%20Access%20Tool&DB_Short_Name=CTPP%202000 Previously these
were available by ordering CD copies through the BTS Bookstore. We hope
this web-based system makes it easier for everyone.
The CTPP 3-year (2006-2008) full set of more than 300 tables will be
available using web-based software prepared by Beyond 20/20 under
contract to AASHTO's CTPP program. The software will be in beta-test
this month (October).
4. ACS Workshop at TRB Annual Meeting, Sunday, January 23, 2011.
If you are planning to attend TRB in January, please remember to arrive
in time to attend this data workshop on Sunday. The organizers have
requested the morning session (8:30 a.m. until noon). Topics will
include 2010 Census, ACS standard tabs and Public Use Microdata Sample,
CTPP (3-year and 5-year tabulations), and TAZ delineation software.
5. And, just in case you lost the link to the ftp site with the
County-to-County and Place-to-Place flows from the CTPP 3-year
tabulation, here it is:
ftp://ftp.camsys.com/temp/outgoing/CTPP/New%20CTPP%20ACS/
Please share your work using the new CTPP (2006-2008).
I will be sending another post to the CTPP listserv shortly that
addresses TAZ delineation only.

Dear CTPP community:
I am passing along an announcement for an Association of Public Data
Users (APDU) webinar in which you may be interested.
The webinar is open to non-APDU members for a $50 fee.
You might also want to consider becoming a member of APDU.
http://www.apdu.org/ The last conference (held in September) included
an excellent presentation about data.gov, among many useful sessions.
The CTPP data access software that is being designed and tested by
Beyond 2020 (under contract to AASHTO) will include limited ability to
re-calculate standard errors, e.g. when adding geographic units, or
adding table cells.

Webinar: User Needs for Calculating Standard Errors in the ACS
October 15, 2010
3pm - 4pm EST
Host: Warren Brown, University of Georgia
Presenters: Doug Hillmer, Independent Consultant, and Jane Traynham,
Maryland State Data Center
Description: With the ACS, it is increasingly important that data users
pay attention to standard errors. This session is aimed at helping
users better understand and calculate those errors. What are the
requirements that should be addressed by an online statistical
calculator to facilitate users manipulating published tabulations and
calculating appropriate measures of reliability?
Users needing to calculate the reliability of various estimates-such as
differences between geographic areas, differences over time, ratios, and
proportions-need to have an online tool that facilitates the process.
This webinar is directed at users of the tabulated data from the ACS who
have found it necessary to calculate measures of reliability but find
the process to be arduous, time consuming, and with a high likelihood of
errors. The presenters will share their ideas for the specification of
requirements and seek feedback from the webinar participants.
