[Fwd: RE: CTPP Census Journey to Work Question]

by ed christopher

i am passing this along to the list. i believe that is where frank meant it to go. when posting to the list the list serve address is "ctpp-news(a)chrispy.net". someone along the way slipped the word "owner-" in front of the address which sends the message only to me. also, when responding to the entire list, please make sure to "reply all" to make sure your response goes to the list and not just the person who stimulated the response. -------- Original Message -------- Subject: RE: CTPP Census Journey to Work Question Date: Fri, 30 May 2003 11:42:16 -0400 From: Fred Frank <fred.frank(a)knoxtrans.org> Organization: Knoxville-Knox County MPC To: "'owner-ctpp-news(a)chrispy.net'" <owner-ctpp-news(a)chrispy.net> Hello, The Census data for journey to work is a one-way figure. The Knoxville MSA average for a home to work trip is 23.2 minutes. It would also be representative for a work to home trip, so you could double that figure to get the total time a person would spend traveling to and from work- 46.4 minutes. Hope this helps.

Re: [CTPP] Census Journey to Work Question

Dan, I understand that the trip home often takes longer because there's more congestion in the pm (because there are more non-work trips being made during pm rush hour than during am rush hour).

RE: [CTPP] Census Journey to Work Question

by Murakami, Elaine

Here is a link to the Census "long form" which includes the "journey to work" questions. http://www.census.gov/dmd/www/pdf/d02p.pdf Yes, it only the trip TO work. And, yes, you can double it to approximate a "round trip." Results from the National Household Travel Survey (NHTS) http://nhts.ornl.gov/2001/index.shtml show that many more people STOP on their way home from work, we call this "trip chaining." Results from the 1995 NPTS show that 60% of women, and nearly 50% of men make a stop on their way from work to home. So, the result is the that trip from work to home, including one or 2 stops is often considerably longer than the trip TO work. http://www-cta.ornl.gov/npts/1995/Doc/Chain2.pdf Thank you for sharing the Arbitron application. You may also be interested in the county-level CTPP profiles that were released last October. http://www.fhwa.dot.gov/ctpp/dataprod.htm These have a few tables, including comparisons to 1990 results, and tables of commute time by mode of travel, and vehicle availability by household size. This same link also has information on the Census Bureau's County-to-County worker flow data. The CTPP Part 1 (residence) tables will begin release in a few weeks. They will be mailed initially to the State DOTs and MPOs for their review, before they are released broadly and publicly. Elaine Murakami Federal Highway Administration 206-220-4460

Re: [CTPP] American Community Survey - May 13, 2003 Hearing

by Chuck Purvis

TO: CTPP-News; Nathan There were some slight problems in the PDF and WORD files I uploaded to our FTP site. So, I re-up-loaded them to our FTP site, as well as our HTTP (hypertext transfer protocol - - web page) site: ftp://ftp.abag.ca.gov/pub/mtc/census2000/ACS/ACS_Hearing_MAY1303/ http://www.mtc.ca.gov/datamart/census/acs/ If the FTP doesn't work, there may be a "firewall" issue. I wouldn't know if it's from our end or your end. Perhaps your systems administrator could tell. An any case, I've made duplicates of the same file at the http url, shown above. Maybe Ed and I can update trbcensus.com to add links to these documents on the ACS page? Chuck Purvis ************************************************************** Charles L.

CTPP 2000 back into PRODUCTION MODE

by Murakami, Elaine

HURRAH! The Census Bureau is now back to getting CTPP Part 1 tables out the door! -----Original Message----- From: Clawson, Dave Sent: Friday, May 16, 2003 9:38 AM To: SCOP Cc: Horsley, John; Oakley, Janet; Basso, Jack Subject: Good news about the CTPP 2000 Late yesterday, we received word from Nancy Gordon of the Census Bureau that they are reversing their April decision to withhold 10 additional CTPP tables from release because of disclosure concerns. Over the past several weeks, Jack Basso and I at AASHTO along with staff from BTS and FHWA have been discussing with Census Bureau staff our concerns about the April decision and the major negative impact it would have on the 2000 CTPP package for the States and MPOs. I spoke with Phil Salopek of the Census Bureau today regarding the revised schedule now that they have the green light to start releasing these materials (CTPP Part 1). Phil indicated that the first of the state CDs would go out in early June, with all of the states and MPOs having their respective CDs by the end of July. Phil said that they will do a limited production of CDs initially (two per MPO plus the quantity requested by the State DOT). Once a State and its MPOs have their CDs, they would have about a one month period to use it and let the Census Bureau know of any corrections needed. Once a state CD has been through that review process and any corrections have been made, then a larger quantity of CDs would be prepared for public distribution.

CTPP is delayed and we have no expected date of delivery

by Murakami, Elaine

Just when the Census Bureau was ready to issue CTPP Part 1, everything has ground to a halt. On April 18, 2003, the Census Bureau advised the CTPP Working Group that 10 tables in CTPP Part 1 could not be released. These 10 tables were in addition to the 3 tables that were already slated to be eliminated, given earlier stated concerns with the quality of Group Quarters data from the decennial census. The logic that would eliminate these 10 tables would ALSO eliminate two very critical tables in Part 3 (flow from home to work), these are: 3-2. Number of Vehicles in Household (4) by Means of Transportation to Work (8), and 3-7. Household Income (5) by Means of Transportation to Work (5). It is not clear what logic the Census Bureau would apply to Part 2 and whether any of those Tables would also be eliminated. AASHTO is discussing their concerns with the Census Bureau, and we hope to have a resolution soon. However, we cannot even estimate when the CTPP Part 1 will now be released. Your truly, with major disappointment, and discourgagement, Elaine Murakami Federal Highway Administration Office of Planning 206-220-4460

Re: CTPP Part 1?

by Elizabeth Hartmann

Has there been a schedule change for release of the CTPP (beyond county-to-county flows)? We had been expecting the data in April, and the calendar says tomorrow is May! There have been anouncements on the listserve for initial release of PUMS-1 percent and SF-4, but no correspondance on the queue for the finer-detailed CTPP Part 1. Does anyone know where Minnesota might be on the distribution list? We'd heard about some issues/delays, but are unsure about the details. Thanks very much!
