A Fond Farewell to TREC Associate Director Hau Hagedorn

Nov 28, 2023

After 17 years of service to TREC, Portland State University's Transportation Research and Education Center, associate director Hau Hagedorn is moving on to a new position as the Community Investments Manager for Oregon Metro. We will miss her as a colleague, as a model for transportation photos (here she is on the cover of our 2022 Annual Report) and as a seemingly inexhaustible source of energy and inspiration!

During her time at TREC, Hau devoted tireless efforts to improving access to transportation and mobility for people of all ages, communities, and incomes. Her perseverance and commitment have been recognized in the form of numerous accolades and awards. In 2020, she received the CUTC-ARTBA Award for Administrative Leadership from the Council of University Transportation Centers (CUTC) and the American Road & Transportation Builders Association (ARTBA), and the same year she was appointed ...

Using Health Indicators in Transportation Plans

Aug 21, 2023

As a social determinant of health, transportation significantly contributes to people's well-being. Walkable, bikable, transit-oriented communities are associated with healthier populations. People in such communities are more physically active, less likely to be injured due to a crash, and less exposed to air pollution.

Because of these and other factors, 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 actually being used and what their impact is on policy.

Research conducted by Kelly Rodgers, a National Institute for Transportation and Communities (NITC) Dissertation Fellow, 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.

"I have for some time been working at the intersection of health and transportation, and was interested in how health could be better integrated into transportation decision making. And I have also previously done work on performance measures. And so I kind of combined those two things, to see if health-related indicators were a way of getting transportation agencies to consider health in transportation planning," Rodgers said.

New Publication Evaluates the Potential of Crowdsourced Data to Estimate Network-Wide Bicycle Volumes

Jul 31, 2023

How can emerging data sources most effectively be integrated with traditional sources? A new article in the July 2023 issue of Transportation Research Record: Journal of the Transportation Research Board reports that rather than replacing conventional bike data sources and count programs, old “small” data sources will likely be very important for big data sources like Strava and StreetLight to achieve their potential for predicting annual average daily bicycle traffic (AADBT).

The article, "Evaluating the Potential of Crowdsourced Data to Estimate Network-Wide Bicycle Volumes," was authored by TREC researchers Joe Broach, Sirisha Kothuri and Nathan McNeil of Portland State University along with Md Mintu Miah, Kate Hyun and Stephen Mattingly of the University of Texas at Arlington, Krista Nordback of the University of North Carolina, Chapel Hill; and Frank Proulx of Frank Proulx Consulting, LLC.

Transportation agencies have invested heavily in count infrastructure and models to estimate motor vehicle volumes through networks. Efforts to develop network wide bicycle volume estimates have been hampered by lack of bicycle counters and limited other data sources from which to draw volume estimates. Until recently, most data on bicycle activity came from national or regional household travel surveys, along with observed counts of cyclists—...

How Low-Income Riders Are Affected by Low-Cost Transit Fare Programs

Apr 24, 2023

In recent years, there has been a nationwide push to move from using cars to using other modes of transportation. The benefits of active transportation (that is, walking, biking, and even using public transit) are widely known. Not only can these modes of transportation increase people’s physical and mental well-being, but they also cut down on the negative effects of cars (like their contributing to greenhouse gas emissions and air pollution).

In an effort to encourage more people to use public transportation, and to reduce disparities among riders of varying incomes, Portland, Oregon’s TriMet system developed a low-income fare option for its Honored Citizens Fare (HCF) program. The purpose of the paper—titled “Do Travel Costs Matter? Using Psychological and Social Equity Perspectives to Evaluate the Effects of a Low-Income Transit Fare Program on Low-Income Riders”—was to determine if the low-fare option works to increase access to transit and improve well-being among low-income riders in comparison to other riders. If it does, then it is an effective way to identify and meet the needs of this population and distribute the benefits of transportation investments more fairly.

The HCF program reduces the fare of the public transportation that TriMet provides, which includes buses and...

New LiDAR System Pinpoints Pedestrian Behavior to Improve Efficiency and Safety at Intersections

Mar 06, 2023

Pedestrian safety is critical to improving walkability in cities. To that end, NITC researchers have developed a system for collecting pedestrian behavior data using LiDAR sensors. Tested at two intersections in Texas and soon to be tested at another in Salt Lake City, Utah, the new software created by a multi-university research team is able to reliably observe pedestrian behavior and can help reduce conflicts between pedestrians and vehicles at signalized intersections. The Utah Department of Transportation (UDOT) is already working on implementing this new system to improve data collection at intersections.

Learn more in a free webinar May 18. 

The LiDAR system can especially improve multimodal travel at intersections with permissive left turns, which are indicated by a flashing yellow arrow. Previous research has shown that where a flashing yellow arrow, or FYA, is present, cars searching for a gap in traffic may not look for pedestrians. To remove the risk to people walking, some signals are programmed to turn off the FYA when a walk button is pushed. But...

The NITC Guide to the 2023 Transportation Research Board (TRB) Annual Meeting

Jan 03, 2023

The 102nd annual meeting of the Transportation Research Board (TRB) will be held January 8–12, 2023 in Washington, D.C. Supported by funding from the U.S. Department of Transportation, research from the National Institute for Transportation and Communities (NITC) will be featured at this annual gathering. The spotlight theme for the 2023 meeting is Rejuvenation Out of Disruption: Envisioning a Transportation System for a Dynamic Future.

Below are a few highlights of research being presented by transportation experts from our participating NITC-funded campuses: Portland State University (PSU), University of Oregon (UO), University of Utah (UU), University of Arizona (UA), and University of Texas at Arlington (UTA). Check out our full NITC guide for all of the sessions:

NITC Dissertation Fellow To Explore How Gender Expression Influences Travel Behavior Decisions

Dec 07, 2022

The National Institute for Transportation and Communities (NITC) is proud to introduce our newest Dissertation Fellow, Nicholas Puczkowskyj of Portland State University, who was awarded $15,000 for his doctoral research project: Expanding Transmobilities: An Art-Informed Methodology For Genderdiverse Travel Behavior.

"My dissertation focuses on understanding how genderdiverse individuals' gender identity influences their travel behavior and travel decisions. I use an art-based methodology by operationalizing collage and mental maps to delicately capture these data. I believe this work will support mobility justice research and the greater social justice movement by further solidifying the field of transmobilities. Additionally, this research seeks to push the boundaries of transportation research by illustrating the power of art as a modality for travel behavior research," Puczkowskyj said.

There is a significant gendered travel behavior research gap in the transportation literature. A plethora of transportation literature identifying and contrasting cisgender disparities exists, but more inclusive approaches to genderdiverse identities remain scarce. The burgeoning field of transmobilities investigates transgender mobility and evolved from the nexus of mobility justice and gender studies by studying transgender experiences on public transit.

Nick's dissertation expands...
