Exploring Data Fusion Techniques To Estimate Network-Wide Bicycle Volumes, Sirisha Kothuri, Joseph Broach, Nathan Mcneil, Kate Hyun, Stephen Mattingly, Md. Mintu Miah, Krista Nordback, Frank Proulx

TREC Final Reports

This research developed a method for evaluating and integrating emerging sources (Strava, StreetLight, and Bikeshare) of bicycle activity data with conventional demand data (permanent counts, short-duration counts) using traditional (Poisson) and advanced machine learning techniques. First, a literature review was conducted, along with cataloging and evaluating available third-party data sources and existing applications. Next, six sites (Boulder, Charlotte, Dallas, Portland, Bend, and Eugene) that represented a variety of contexts (urban, suburban) and geographical diversity were selected. Of these, Boulder, Charlotte and Dallas constituted the basic sites, where one year of data (i.e., 2019) was used for modeling. Portland, Bend, and …

Data From: Updating And Expanding Lrt/Brt/Sct/Crt Data And Analysis, Robert Hibberd, Arthur C. Nelson, Kristina M. Currans

TREC Datasets and Databases

This data supports the LRT/BRT/SCT/CRT Development Outcomes FINAL PHASE.

The FINAL PHASE will allow us to use factor/cluster analysis to create typologies of station areas to assess the extent to which types of stations (as opposed to transit systems as a whole) make a difference in economic development (based on LEHD data), and people (census data) during the periods before, during and after the Great Recession as appropriate for each system and mode. It will also allow us to refine hedonic regression analysis.

Data From: Market Segment Prediction Tool, Philip L. Winters, Amy Lester

TREC Datasets and Databases

Social marketing seeks to develop and integrate marketing concepts with other approaches to influence behaviors that benefit individuals and communities for the greater social good. Social marketing is a useful transportation demand management (TDM) planning approach to promote travel-behavior change, and combines at least seven distinguishing features that sets it apart from other popular, behavior-change planning approaches, such as education and mass media campaigns. These seven features include a focus on socially beneficial behavior change; a strong consumer orientation; the use of audience segmentation techniques and the selection of target audiences; the use of marketing’s conceptual framework (marketing mix and …

Nationwide Worker Database To Analyze Transit Outcomes Using An Economic And Demographic Lens, Robert Hibberd, Arthur C. Nelson

TREC Datasets and Databases

This extensive database project provides demographic data for workers, both in terms of where they live and where they work, for 39 U.S. Metropolitan Statistical Areas (MSAs). Planners and researchers can use this database to assess the extent to which transit stations and station areas are associated with economic and demographic change, and to forecast similar magnitudes of change through proposed new or expanded transit systems. Specific data elements include job numbers based on job sector, earnings, race, education, sex, and distance of census blocks to transit separated by mode type. Data were extracted as part of a larger project …

Following The Money From Investments To Outcomes, Robert Zako, Rebecca Lewis

TREC Project Briefs

While it’s accepted that mixed-use development promotes active travel, researchers don’t have a consensus on exactly how land use determines people’s travel patterns.

The research examined:

• The relationship between pedestrian travel and land use mix;
• The impact of land use mix on pedestrian travel;
• How operationalizing land use mix influences individual travel behavior

This work contributes theoretical and empirical tools for research and practice in transportation and land use planning.

Better Outcomes: Improving Accountability & Transparency In Transportation Decision-Making, Robert Zako, Rebecca Lewis

TREC Final Reports

This report aims to help policymakers and staff at all levels of government make transportation investments that serve the public better.

Amazingly, we simply don’t know how effective government spending is at achieving the outcomes the public expects and has been promised! Clearly, taxpayer dollars buy roads, bus service, airports, ferry service, and other transportation facilities and services. But it is unclear how well such investments help get people where they want to go, create jobs, improve public health, support community development, and provide other benefits. In other words, it is uncertain how cost-effectively the means (transportation investments) achieve the …

Affordable Housing As A Prerequisite For A Safe, Healthy, Equitable Transportation System: Evidence From A Nationwide Evaluation Of Location Efficiency Within The Low-Income Housing Tax Credit (Lihtc) Program, Arlie Steven Adkins

PSU Transportation Seminars

Mountains of research over the last several decades show that how we get around and how much physical activity we get are closely linked with the built environment of the neighborhoods where we live. This means that the health, economic, and environmental benefits associated with active travel and transit are place-based and that affordable housing in walkable, location efficient places needs to be thought of as a critical component of planners’ efforts to provide safe, healthy, and equitable transportation systems. This talk will provide an overview of the links between affordable housing and transportation planning and present research findings from …

Factors Associated With The Bicycle Commute Use Of Newcomers: Analysis Of The 70 Largest U.S. Cities, Ryan Dann

PSU Transportation Seminars

Bicycling is known to produce benefits for cities, in regards to reducing levels of congestion, generating positive health outcomes, and providing affordable transportation options to low-income families. Conventional analysis of urban bicycle commuting does not currently consider the importance of separating migrant, or “newcomer,” bicycle commute use from pre-existing resident bicycle commute use. The goal of this paper is to provide additional information on individual, social, and environmental factors that influence newcomer bicycle use for commuting purposes. This cross-sectional study used data from the 2007-2011 American Community Survey (5-year Estimates) to analyze the bicycle commute use of newcomers in the …

Building And Maintaining A Statewide Transportation Framework, Kenneth Dueker, Paul Bender

Center for Urban Studies Publications and Reports

Creating and maintaining up-to-date sharable Geographic Information SystemsTransportation (GIS-T) data is challenging. Many states are working on Transportation Framework efforts to build a complete, consistent, and current transportation data layer in conjunction with the NSDI and Geospatial One-Stop efforts. This paper summarizes an effort that systematically re-examined transportation data sharing issues as part of the development of a Transportation Framework for the State of Washington. Business needs were assessed in terms of spatial and temporal accuracy needs of stakeholders and users of a state-wide Transportation Framework. A conceptual model was developed for a Transportation Framework with emphasis on data flows …

A Clearinghouse Approach To Sharing Transportation Gis Data, Kenneth Dueker, J. Allison Butler, Paul Bender, Jihong Zhang

Center for Urban Studies Publications and Reports

Updating and maintaining Geographic Information Systems-Transportation data (GIS-T data) is proving difficult. Different database formats needed to support diverse applications leads to inconsistencies and inaccuracies, and duplication in updating. A clearinghouse approach is recommended for the collection and dissemination of new transportation features that can be segmented in different ways to meet the needs of various applications and inserted to update existing GIS-T databases. The clearinghouse approach is advantageous in that it is based on collecting data about new or changed transportation features once and uses the data many times to update existing databases.

A Framework For Gis-T Data Sharing, Kenneth Dueker, J. Allison Butler

Center for Urban Studies Publications and Reports

This paper develops a framework and principles for sharing of transportation data. The framework is intended to clarify roles among participants, data producers, data integrators, and data users. The principles are intended to provide guidance for the participants. Both the framework and the principles are based on an enterprise GIS-T data model that defines relations among transportation data elements. The data model guards against ambiguities and provides a basis for the development of the framework and principles for sharing of transportation data. There are two central principles. First is the uncoupling of graphics, topology, position, and characteristics. Second is the …

Sharing Transportation Gis Data, Kenneth Dueker, Paul Bender, Jihong Zhang

Center for Urban Studies Publications and Reports

Updating and maintaining Geographic Information Systems-Transportation data (GIS-T data) is proving difficult. Different database formats needed to support diverse applications leads to inconsistencies and inaccuracies, and duplication in updating. Dueker and Butler (1998) have proposed an Enterprise GIS-T data model that unbundles the various components of transportation data (network links, cartography, and attributes) to facilitate generating application-specific networks, and which eases updating and maintenance. However, developers of existing application-specific databases that employ integrated data models that bundle the network link with cartography and attributes are reluctant to step back to an intermediate form for managing their data. Consequently, attention is …

A Primer On Gis-T Databases, J. Allison Butler, Kenneth Dueker

Center for Urban Studies Publications and Reports

This paper describes the primary database design approaches that have been and are being used in geographic information system applications for transportation (GIS-T). While not intending to be exhaustive, the paper covers the primary approaches used in federal, state, and local transportation agencies.

A Proposed Method Of Transportation Feature Identification, J. Allison Butler, Kenneth Dueker

Center for Urban Studies Publications and Reports

Geographic information systems (GIS) are being increasingly deployed by transportation agencies to help them display, review, and utilize data. The primary items of interest are transportation facilities and services, which may take the form of highways, airports, bus routes, and seaports, among others. Using GIS software, transportation facilities are represented as geometric shapes; i.e., points, lines, and areas. However, it is increasingly apparent to GIS users in the field of transportation that a geometry-based approach is not sufficient.

The offered solution is to develop a feature-based GIS approach for transportation. The central requirement of such an approach is to have …

The Evolution Of Federal Transit Policy, Sy Adler

Urban Studies and Planning Faculty Publications and Presentations

Examines how the US federal government came to subsidize a greater share of transit industry costs than most other national governments. Since World War II, downtown activists sought to boost their transit systems in the face of increasingly intense competition from suburban business centers; the transit systems of Los Angeles and San Francisco in particular were shaped by this competition. Downtown activists tried, with varying success, to influence the newly formed regional transit agencies and the Federal Department of Transportation, created in 1964. The federal government's role in urban transit has been characterized by a tension between economic rationalization and …

An Analysis Of Bus Ridership Potential To Oregon Health Sciences University Using A Geographic Information System Approach, Richard Lycan, James D. Orrell, Transportation Northwest (Transnow)

Center for Urban Studies Publications and Reports

GIS address-matching and overlay techniques can be used in the analysis of specialized transportation problems. These techniques enhance the spatial resolution of transportation services relative to the locations of potential users of the service. This allows planners to evaluate accessibility issues for identifiable user groups and thus make decisions about the feasibility of adjusting routes or schedules, or providing new services for these users. A case study focused on the commuter base of Oregon Health Sciences University is presented as an example of such an application.
