THE TOPIC 

As a social determinant of health, transportation significantly contributes to well-being through several pathways. Researchers and practitioners have called for health indicators as one way to integrate public health concerns into transportation decision-making. However, it is unclear how indicators are used and what their impact is on policy. This case study of five cities explored how health-related indicators are being used in municipal transportation plans, whether they are institutionalized into transportation agency decision-making processes, and what influence they have on administrative decision-making. In addition, this research also explored the conceptual use of indicators as it relates to social learning and policy change. Finally, this research examined whether health framing was important to policy adoption or change.

KEY LEARNING OUTCOMES

  • Learn which indicator characteristics are important for greatest impact, and at what point in the process
  • Learn which organizational factors are important for institutionalizing indicators into agencies
  • Learn how indicators are used to successfully shape individual beliefs
  • Learn whether framing an indicator as a "health" indicator is compelling

Transportation Seminars at Portland State University have been a tradition since 2000. Formerly known as the Friday Transportation Seminar series, we've opened up PSU Transportation Seminars to other days of the week to better accommodate attendance. You can always watch online via Zoom.

PRESENTATION ARCHIVE

THE TOPIC 

There have been numerous studies on the relationship between travel behavior and built environment over the last few decades. Prior studies have mostly focused on producing point estimates of model coefficients and ended up with a wide range of estimates for the built environment elasticity of travel behavior, including household Vehicle Miles Traveled. With few exceptions, previous studies use data from a single region or a small number of regions, and thus are not able to sufficiently investigate the regional variation in built environment elasticity.

On the other hand, a few papers have addressed the heterogeneity of elasticity among different population groups and neighborhood types, but so far have paid little attention to regional variation of elasticity. In his latest research project, Liming Wang uses the 2009 U.S. National Household Travel Survey and high resolution built environment measures in the Smart Location Database to investigate the Urbanized Area-level variation in the effect of built environment with multi-level mixed effect models. He found that there exist regional variations in the relationship between built environment and household VMT, and, as a matter of fact, there is no significant fixed effect of major built environment factors on VMT after considering urbanized area-level random effect. This presentation will conclude with a discussion of the implications of this research.

KEY LEARNING OUTCOMES

  • The study found that there is variation at the Urbanized Area-level in the relationship between built environment and household Vehicle Miles Traveled (VMT).
  • The study highlights the limitations of previous research, which often relied on data from a single region and produced point estimates of the effect of built environment on travel behavior.
  • The existence of regional variation in the effects of built environment on travel behavior poses a challenge to our understanding of the relationship, but also suggests opportunities for targeted policies.

This three-day workshop offers strategies for building and strengthening communities around increased walking and bicycling. You'll learn and experience firsthand the design of various, successful active transportation programs that incorporate these strategies.

We kick it off with city staff on a behind-the-scenes learning tour of Portland's Sunday Parkways, the city's premiere Open Streets initiative that attracts over 80,000 participants annually. The subsequent days delve into other transportation demand management (TDM) and transportation options programs that play a key role in helping more people to bike, walk, and use transit.

This course offers insights and strategies to make the case for policymakers, inspire communities, and build a movement toward healthier, more active cities. 

IBPI Workshop: Comprehensive Bikeway Design

This year's workshop will be held Aug 25–29, 2025
REGISTER NOW

As Portland, Oregon has put bikeway plans into effect, we’ve learned what works and what doesn’t—how to plan effectively, design correctly and make investments that get results. We’ve distilled those lessons into this course, which covers the fundamentals of bikeway design and planning through an intensive week of interactive classroom, field tours, and design exercises. 

Instructors draw from their years of experience, along with project examples, to highlight practical applications of the principles and techniques covered. The pioneers and leading practitioners in the field will teach the fundamentals of bikeway planning and design through an intensive week of classroom sessions and tours. The instruction and interaction with other participants will bring you up to speed on innovative practice and research and teach you the skills and techniques you need to get started on your next project. 

Over the years, the Portland area has implemented numerous types of innovative bicycle facilities and treatments. Daily field tours provide first-hand experience with these facilities and projects discussed in the classroom. These tours showcase not just the operational qualities but also how bikeway planning affects community livability and economic development.

Upon completion of the course, participants will be able to:

  • Make low-risk investments in proven bicycle plans and facilities
  • Select the appropriate bicycle facility design based on urban form, traffic conditions and multimodal context
  • List the different ways that a bicycle facility can meet or not meet the needs of people who bike
  • Use the FHWA Experiment process to test innovative bikeway design
  • Describe the tradeoffs of designing better facilities to accommodate all road users
  • Identify various options for treating intersections that incorporate bicycle facilities
  • Describe the health benefits of active transportation
  • Identify opportunities, strategies and programs to encourage more people to bike and walk
  • Talk to an engineer and communicate effectively with them about facility requirements
  • Build their personal network with experts from the various facets of bikeway design
  • Feel rejuvenated and excited to go back to work and make an impact!

This course is offered through our Initiative for Bicycle and Pedestrian Innovation program.

WHO SHOULD ATTEND?

Hosted since 2009, our Bikeway Design workshop is designed for transportation engineers, urban planners, advocates, policymakers, municipal staff and other transportation professionals interested in nurturing cycling in their communities. See photos from workshops of previous years.

Students must be able to bike 8–15 miles a day, and expect mild elevation. With daily bike rides, this course is physically demanding. Participants who aren't used to riding multiple miles per day have the option of renting e-bikes (we have a limited number, while supplies last). Having an e-bike gives you the same view and makes it easy to keep up with the group!

"I came into the course hoping to learn new insights on bikeway design and left with all my expectations being exceeded. The TREC staff were amazing during the week providing us with resources and support. Additionally they did a wonderful job putting together a great group of panelists that brought with them a breadth of experience, knowledge and skill."
-2021 attendee

"We are currently in the process of designing some of our first bike lanes. I plan to use the knowledge gained from intersection treatments and shared bike/ped infrastructure to improve our proposals."
-2021 attendee

"I came into the course with very minimal experience with bikeways and how it affects traffic with the implementation of these bike lanes/pathways. The course has taught me that it takes a bit of thinking outside the box to make bikeways work even if it doesn't seem very conventional or helpful."
-2019 attendee

"The course provided guidance on many innovative solutions for enhancing bicycle safety and circulation. The reasons behind prioritizing bicycle travel were also useful, as well as the policy context for focusing on bicycle infrastructure."

The Pacific Northwest Transportation Consortium (PacTrans) is the Regional University Transportation Center (UTC) for Federal Region 10, housed at University of Washington (UW). Each year, PacTrans provides PSU with $150,000 to fund “small research projects.” Those projects must be selected using a competitive, peer-review process. The Year 3 Request For Proposals (RFP) is open now. PSU plans to award no more than three projects. Therefore, individual project requests should range from $30,000 to $70,000. 

Abstracts are due May 6, with full proposals due June 3, 2025.

Download the RFP and other relevant documents, and find instructions for how to submit a proposal, on the PSU PacTrans page.

Portland State University's Transportation Research and Education Center (TREC) is a multidisciplinary hub for all things transportation. We are home to the Initiative for Bicycle and Pedestrian Innovation (IBPI), the data programs PORTAL and BikePed Portal, the Better Block PSU program, and PSU's membership in PacTrans, the Pacific Northwest Transportation Consortium. Our continuing goal is to produce impactful research and tools for transportation decision makers, expand the diversity and capacity of the workforce, and engage students and professionals through education, seminars, and participation in research.

Every time a pedestrian pushes a button to cross the street, it creates a useful data point about how many people are walking through that intersection. Now, transportation planners and engineers in Oregon have easy access to that data: The newest feature we've added to BikePed Portal is a dashboard that lets you explore the Oregon Department of Transportation (ODOT)'s pedestrian push-button data from all over the state.

ODOT has shared this data with Portland State University (PSU) for use in BikePed Portal, so that users can see where and how people interact with pedestrian crossings at signalized intersections. The dashboard (watch a walkthrough here) is still being developed and is anticipated to eventually include data from more agencies in addition to ODOT.

WHY IS THIS DATA HELPFUL?

Many, if not all, active transportation projects rely on pedestrian volumes to measure pedestrian exposure, or the number of potential opportunities for a pedestrian to be involved in a crash with a moving vehicle. By analyzing usage patterns, practitioners can prioritize upgrades at high-demand or problematic locations, ensure compliance with ADA standards, and inform pedestrian infrastructure planning. The potential applications of push-button data are numerous, and just a couple of examples are highlighted below.

The new dashboard is a useful resource to help agencies improve signal timing, accessibility, and safety for all road users, as well as guide future investments in walkability. 

DERIVING PEDESTRIAN COUNTS 

Researchers are exploring methods to convert the push-button data into complete pedestrian counts for the transportation network. At the 2025 annual meeting of the Transportation Research Board (TRB), Sirisha Kothuri, Joe Broach and Elizabeth Yates of PSU presented a study along with Mahyar Vahedi Saheli and Patrick Singleton of Utah State University on "Pedestrian Volumes from Push-Button Traffic Signal Data in Oregon: Estimating Models and Assessing Model Transferability [PDF - add link to poster)" in which they used the ODOT data, along with video recordings, to estimate pedestrian counts. They also developed a workflow to integrate pedestrian traffic counts into ODOT’s enterprise traffic data system. 

The initial research was funded by ODOT, as well as some funding support for the dashboard. Learn about the models used to calculate estimated pedestrian volumes in the final report, or watch a recorded seminar to learn more.

ODOT's research unit has also documented a use case for the data—see Pedestrian Traffic Estimation for Liquidation Costs—and is developing more.

ANALYZING PEDESTRIAN CRASHES

At Utah State, Singleton used similar data in Utah to do safety analysis. One paper examined the frequency and severity of crashes involving pedestrians, and another developed improved methods to predict crashes at signalized intersections. The research team wanted to examine whether the “safety in numbers” effect applies to pedestrian safety in the US. Both papers used push-button data as a novel data source to measure pedestrian exposure.

As pedestrian safety and accessibility continue to be top priorities in transportation planning, innovative uses of existing infrastructure—like push-button data—are opening up new possibilities for research, analysis, and informed decision-making. The addition of this new dashboard to BikePed Portal marks an important step in making pedestrian activity more visible for agencies across Oregon. By leveraging this data, planners and researchers can better understand walking patterns, identify safety risks, and ultimately create safer, more walkable communities. 

As the dashboard grows to include data from more jurisdictions, its value will only increase—offering a powerful tool to support equitable and evidence-based improvements in pedestrian infrastructure.

PARTNER WITH PSU: ADD YOUR DATA TO BIKEPED PORTAL

Cities and agencies interested in partnering across the region to improve transportation data access should reach out to our team at bikepedportal@pdx.edu. We are interested in adding more push-button data, as well as other types of nonmotorized data. 

We accept data in multiple formats (including EcoCounter API, TrafX, manual, turning movement), and convert it all into a standardized format. We offer quality control, quality assurance, and more. Learn about the services that BikePed Portal offers.
