[CTPP] How to Obtain Workers Abroad Data by County of Residence

by Natalie Young

Hello CTPP Users, I am trying to use the CTPP software to obtain the number of residents of each county in Utah who worked outside the United States. I am using the 2006-2010 5-year dataset. Please let me known if you have any direction on how to obtain this data. I set all counties in Utah as my residence geography (29 counties). I selected all options for "Worked Outside United States" as the workplace geography (there are only 3 selections). I selected Part 3 - table A302100 (total workers 16 and over) as my data table. I receive the response that "no valid flows are available for your geographic selections - please modify." I have used CTPP to obtain flow data for the residents of each county in Utah and their workplaces in Utah or the USA, by county. Data on working outside the United States, however, is proving difficult. Is it possible to obtain this data through the CTPP software? Thank you, Natalie Young [Block U Logo] Natalie Young Research Analyst Kem C. Gardner Policy Institute The University of Utah Office: 801-587-9436 gardner.utah.edu

Re: [CTPP] ctpp-news Digest, Vol 149, Issue 3

by Nancy McGuckin

Thanks for the shout out, Don! I did post this as a comment on TMIP: Just a note: in my experience home-based work is seldom the vast majority of morning peak travel: nation-wide it is about 40 percent of vehicle trips in the morning peak, when looking at metro level it can rise to 60 percent or so. Of course the evening peak is even less likely to have home-based work travel. In the 2009 NHTS, just under 20 percent of workers stopped for one or more reasons in the morning before going to work--a stop of 30 minutes or more. This estimate was much higher for women and people with children in the household. The percent of workers stopping during the commute is similar to the estimate in 2001, so while the percent of stops during the commute may not be growing it remains substantial. These are often 'pick-up/drop-off' trips, and it may pay to look at the passenger's purpose to understand what kind of trip (school, other workers, etc.) It is the case perhaps that the non-work travel vehicle travel occurs on arterial more than highways, and may be spread out rather than in the most congested corridors. But for overall vehicle travel estimation and flows we should keep in mind the impact of these non-work trips and stops.

[CTPP] SAS Question

by Ed Christopher

Below is a response to Mara's question that got bounced from the mail list since it was from a non subscriber. ------------------- Subject: RE: [CTPP] geocoding in SAS From: "Seitz, Leonard E(a)DOT" <leonard.seitz(a)dot.ca.gov> Date: 8/9/2016 11:43 AM To: "Portillo, Diana M(a)DOT" <diana.portillo(a)dot.ca.gov>, "ctpp-news-bounces(a)chrispy.net" <ctpp-news-bounces(a)chrispy.net> This SAS/Graph Procedure should work: Overview: GINSIDE Procedure The GINSIDE procedure compares a data set of X and Y coordinates to a map data set containing map polygons. The procedure determines whether the X and Y coordinates for each point fall inside or outside of the map polygons. If the point falls inside a polygon, then the ID variable is set to the ID value of that polygon. For example, if a map contains states, then the ID variable of the output data set is set to the state that contains the point. The GINSIDE procedure can be used with the SAS/GRAPH map data sets and the results can be used to annotate onto a map with the GMAP procedure. Note: Avoid unpredictable map results with points that fall on the border of a polygon by using the INCLUDEBORDER option. This option includes points that are on the border of a polygon in the output data set. These points are identified by the variable named _ONBORDER_ with a value of 1. Copyright © SAS Institute Inc.

[CTPP] variance replicate estimate tables

The Census now has variance replicate estimates for certain ACS tables. This is intended to improve certain derived MOE's.
