Request for Letters of Interest to write tech papers for the upcoming Applying Census Data for Transportation Conference

by Weinberger Penelope

Request for Letters of Interest - Papers - Applying Census Data for Transportation The American Association of State Highway and Transportation Officials (AASHTO), is a nonprofit, nonpartisan association representing highway and transportation departments in the 50 states, the District of Columbia, and Puerto Rico. Our primary goal is to foster the development, operation, and maintenance of an integrated national transportation system. The Census Transportation Planning Products Program (CTPP) is a Technical Service Program of AASHTO. The CTPP is seeking letters of interest for the preparation of commissioned papers and presentation of those papers at an upcoming conference. In November 2017, AASHTO CTPP and the Transportation Research Board (TRB), are hosting a conference; Applying Census Data for Transportation. Qualified authors are sought to prepare four commissioned papers. The papers will be presented at the conference and used to assist the CTPP in the development of future products. Four separate paper topics have been identified and are presented below. 1. TAZs - How do we move forward? TAZs have been a part of the CTPP/UTPP data product since the inception of the tabulation. However, over time TAZs have become very costly to produce, redundant with other geographies and confusing in their structure. This paper will take an objective look at the CTPP TAZs and produce an assessment of the issues surrounding the continued production of TAZs for Census data. This assessment shall include examination of TAZ costs, their usefulness/utility, and data quality. The paper shall also discuss the other geographies that exist, and the pros and cons of continuing to use TAZ geography. This paper will help frame the discussion for future TAZ requests. 2. Workplace Data - Achieving its potential. Workplace data is one the keystones of the CTPP/UTPP data products that separate it from all other standard Census data products. While the workplace data has been available since the first (1970) UTPP, the Oversight Board believes that this data is underutilized. To help remedy that situation this paper will discuss the myriad uses of workplace data beginning with examples from current applications, and include perspectives of other possible uses of the data. 3. Keeping the Census data relevant. The data landscape is changing in terms of both data availability and the demands for new and more types of data. New data from sources such as mobile devices, GPS, social media and crowd-sourcing expand the possibilities of data collection and analysis. This paper will explore how Census data (CTPP, ACS, LEHD) relates to these emerging and evolving data sets. Will Census data stay relevant? Can Census data be combined or integrated with these private data sets? Can Census data answer the policy questions of tomorrow? 4. Supporting Transportation Performance Management and Metrics with Census data. Transportation Performance Management (TPM) and Metrics are an ever increasing component our transportation decision and policy processes. As these TPM processes mature Census data will likely be used to support them. This paper will describe the best uses of ACS and CTPP data to support different TPM activities. The importance of the Census data and the need for guidance on consistent data uses should be emphasized. The Conference Planning Team will select one author or team of authors per topic. Anyone may submit a Letter of Interest that demonstrates expertise in the topic area, and an author commitment to attend the conference to present the work. Authors must submit a separate Letter of Interest for each topic they wish to develop. TRB and the CTPP will retain all rights to publish the papers in the conference proceedings and will provide proper citation to the author. Selected authors will work with two Conference Planning Committee members who will provide direction and support for the development of each paper. Papers should be between 12 to 15 pages in length, but may be shorter or longer depending on content. Funding (up to $8,500 per paper), is available to cover conference travel, registration expenses and a stipend for producing the paper. Authors who are unable to accept the funding may still submit Letters of Interest and will be considered viable contenders. Letters of Interest shall demonstrate experience and expertise in the subject matter, and detailed qualifications to write a paper on the selected topic. Letters of Interest should not exceed three single-spaced pages. Letters are due by 5 p.m. CDT on December 9, 2016 via email to Ed Christopher (edc(a)berwyned.com), with a copy to Penelope Weinberger (pweinberger(a)aashto.org). All authors will be notified via email regarding the disposition of their submissions. Please direct any questions you may have in email to Ed Christopher (edc(a)berwyned.com) before November 23, 2016. AASHTO reserves the right to reject any or all Letters of Interest, to waive any or all information or irregularities, and to negotiate with selected authors.

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.

SAS Question

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@DOT" <leonard.seitz(a)dot.ca.gov> Date: 8/9/2016 11:43 AM To: "Portillo, Diana M@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.
