The mission of the Transportation Research Board is to provide leadership in transportation innovation and progress through research and information exchange, conducted within a setting that is objective, interdisciplinary, and multimodal. The Transportation Research Board is distributing this E-Circular to make the information contained herein available for use by individual practitioners in state and local transportation agencies, researchers in academic institutions, and other members of the transportation research community. The information in this E-Circular was taken directly from the submission of the authors.

Lawson Brian McKenzie Karen Miller Jennifer Murray Kevin Tierney Penelope Weinberger Transportation Research Board Staff Thomas M. Palmerlee, Associate Division Director Mai Quynh Le, Associate Program Officer Transportation Research Board 500 Fifth Street NW Washington, D.C. www.trb.org Preface eeting in Kansas City, Missouri, November 14–16, 2017, 115 participants attended the 2- Mday Census Conference—Applying Census Data for Transportation: 50 Years of Transportation Planning Data Progress—reflecting on past accomplishments, current lessons learned, and the future of the Census and related data products. The Transportation Research Board organized the event, with support from the American Association of State Highway Transportation Officials Census Transportation Planning Products (CTPP) program and the U.S. Department of Transportation. A pre-conference CTPP workshop focused on insights and techniques for using the CTPP. During the opening reception, 13 researchers presented their posters. Data sets covered during the conference included the Decennial Census; the American Community Survey; the Longitudinal Employer–Household Dynamics (LEHD); LEHD Origin– Destination Employment Statistics; Public Use Micro Samples (PUMS); and the National Household Travel Survey (NHTS). Ed Christopher, Federal Highway Administration (retired, now an independent consultant), chaired the planning committee. Committee members provided expertise in transportation planning, data analysis, Census data, private- and public-sector data, and education and training. The planning committee was solely responsible for organizing the conference, preparing the call for abstracts, assisting in the solicitation of four commissioned papers to address topics in conjunction with the CTPP Oversight Board, reviewing the submitted abstracts, and developing topics for breakout and panel sessions, including guidance for the facilitated discussion sessions. Catherine T. Lawson, from the State University of New York, Albany, served as the conference rapporteur and prepared this document as a factual summary of what occurred at the conference. The conference provided a forum for participants to share experiences with the use of Census data, including new techniques for integrating different data sets for use in transportation planning and decision making. Participants also learned about recent and forthcoming Census products (e.g., updates in the CTPP software). The conference further provided an opportunity for participants to discuss opportunities, limitations, and challenges involved in using Census data, data available from the private sector, and data from global positioning systems and other technologies. Finally, participants were able to discuss research and training needs associated with applying Census data and data from other sources to transportation planning and decision making. This conference summary report follows the conference agenda. The presentations made in each session are summarized. The opening panel included Deborah Stempowski, from the Census Bureau, sharing the progress being made with the planning and preparations for the 2020 Decennial deployment. The first breakout session included a retrospective on original Census data products (e.g., Urban Transportation Planning Package), an introduction to the CTPP and a presentation of the first commissioned paper and facilitated discussion on the use of the CTPP for performance measures. The evening reception provided ample opportunity for the authors of the 13 posters to share their findings with conference participants, exploring a wide range of Census data topics. Additional sessions covered activities at the Census Bureau, the use of Census data for equity analysis, and advanced data analysis. The second commissioned paper and facilitated discussion focused on transportation analysis zones and the current issues surrounding the geographies for the 2020 Census and beyond. The third commissioned paper and facilitated v discussion explored emerging “Big Data” opportunities and challenges associated with the use of private-sector data and how to keep the Census data relevant. Additional breakout sessions discussed PUMS and Public Use Micro Sample Areas, transportation modeling, and applications for alternative modes. The fourth commissioned paper and facilitated discussion compared various options for workplace data including: LEHD, NHTS, and private-sector options. The two final breakout sessions looked at the future of data for transportation planning and methods for comparing Census data sets. According to Catherine T. Lawson, the plan for this conference is to provide attendees with lessons learned from the past, information on what is happening today and in the future, and how best to take advantage of data assets to inform transportation planners and decision makers. Key topics include methods and opportunities for complementing data products and putting together new ways of thinking, particularly with the CTPP. When the 2020 Census data is made available, using their Application Programming Interface at the Census, researchers and planners will be able to start answering their questions. There is time between now and when that data arrives to make plans for new visualizations, data analytics, data combinations, and data fusions products. Cloud computing will be

A shapefile is a geospatial data format for use in geographic information system (GIS) software. Shapefiles spatially describe vector data such as points, lines, and polygons, representing, for instance, landmarks, roads, and lakes. The Environmental Systems Research Institute (Esri) created the format for use in their software, but the shapefile format works in additional Geographic Information System (GIS) software as well. 1.2 What are TIGER/Line Shapefiles? The TIGER/Line Shapefiles are the fully supported, core geographic product from the U.S. Census Bureau. They are extracts of selected geographic and cartographic information from the U.S.

This guidebook is intended to provide tribal governments and their transportation planning personnel, assistance in understanding the ADOT planning and programming processes and associated funding sources. ADOT is committed to working cooperatively with all tribal governments in Arizona to assure that critical transportation system needs are met on tribal lands. This Guidebook is organized to first provide background on the State Highway System and its relation to tribal lands and the ADOT engineering management districts. Second, it explains ADOT’s vision, mission, goals, and responsibilities in relation to management of the state transportation system. Third, it provides tribal governments with an overview of the ADOT planning and programming process for major transportation improvement projects. Finally, it provides a summary discussion of ADOT’s funding sources for transportation improvement. ADOT also has additional resources for tribal transportation funding available upon request. This second edition of the ADOT Transportation Planning and Programming Guidebook for Tribal Governments is not all inclusive of every detailed process used by ADOT; it is intended to provide tribal governments with a basic understanding of the current planning and programming processes as they relate to tribes.
