RE: [CTPP] information on average commuter travel time in the U.S.

by Elaine.Murakami＠dot.gov

In the NHTS Summary of Travel Trends, page 13, the average person trip length for "to/from work" is 11.8 miles (that would be ONE way, not round trip). There is some difficulty in analysis because of trip chaining, so when someone goes from work-to-shop-to-home, this would not be measured in miles as a work to home trip. http://nhts.ornl.gov/index.shtml This page has a link to the pdf of Summary of Travel Trends. By the way, what Liang Long was referring to was the NHTS on-line table generator. It is also accessible from the NHTS main webpage. After you register, you can easily tabulate (1-way, 2-way, 3-way cross tabs, with subsetting) many variables without having to do any programming. Then, you can output as a spreadsheet or html.

[CTPP] 5-year tables

by Kendra Watkins

Hi all, I am trying to pull together some information about the future 5 year CTPP release for the small area worker flows... what to expect in terms of variables, crosstabs, timeline etc. I've checked the primary sites but maybe I'm missing it. Specifically, does anyone know if the tables in the 5-year product will be the same as what is offered in the 3 year? Thanks in advance.

[CTPP] IPF macro?

by Krishnan Viswanathan

I am not sure if my original post came through and if its a copy i apologize for reposting (computer issues). Original email below. Unless I am missing something, Elaine's challenge has not yet been met or not responded to on this list. Anyway, while trying to IPF a table in R i ran across this resource (http://www.demog.berkeley.edu/~eddieh/datafitting.html) that might be useful to meet Elaine's challenge (there is a bunch of R code that will help meet the challenge). Elaine has already given Age x Mode, and Gender x Mode. Link to Age x Gender for workers 16 years and older [no MOEs included and obtained after raking the marginals of tables B08101 and B08006] given below so that all the data elements are available to meet her challenge.

RE: [CTPP] IPF macro?

by Elaine.Murakami＠dot.gov

Here is the challenge! I do not know how to do IPF, but I know that many of you out there can do it! Attached are: ACS B08101 ; ACS B08006 for Maricopa County Arizona. You can ignore the MOE cells for this IPF challenge. Also attached is a 3-way tabulation using IPUMS for Maricopa County AZ. All are using 2009 ACS. You will note that carpool is not broken out, as the question is really in 2 parts (what mode, and then how many people), so this table could be re-done by creating a carpool variable, if you wanted. We have an archived webinar on using IPUMS, if you are interested in making your own tabs using ACS PUMS. http://ctpp.transportation.org/Pages/webinardirectory.aspx Elaine -----Original Message----- From: ctpp-news-bounces(a)chrispy.net [mailto:ctpp-news-bounces(a)chrispy.net] On Behalf Of Erlbaum, Nathan (DOT) Sent: Friday, March 11, 2011 11:42 AM To: ctpp-news(a)chrispy.net Subject: RE: [CTPP] 2010 Data Release Watch Noted below is a question and a response that appeared on the list serve earlier today and that suggests a solution method to creating data that almost exists but is needed.
