In the latest instance of taking research to practice, researchers at Oregon Tech have completed a pilot section of trail using a NITC-developed sustainable paving method. A quarter-mile section of the Klamath Geo Trail, just east and up the hill from the Oregon Tech Klamath Falls campus, has been successfully resurfaced using volcanic ash from Mount Mazama. Learn more in a free webinar on February 23, 2023: Applying a Mt. Mazama Volcanic Ash Treatment as a Trail Accessibility Improvement.

The researchers explain and demonstrate the process in this NITC research video:

In a big step forward for nonmotorized planning, a dashboard with bike data from the Washington, D.C. metro area is coming to BikePed Portal. Previously, a planner looking to see the latest biking numbers for the nation's capital would have to look at info from several jurisdictions, including Arlington County, the City of Alexandria, the District Department of Transportation, Fairfax County, Montgomery County, and the National Park Service, which manages counters on several trails and natural areas in the greater metro area.

Now, with funding from a National Park Service (NPS) Cooperative Ecosystem Studies Unit (CESU), a unique program that facilitates partnerships between federal and non-federal entities and research institutions, Virginia Tech and the University of North Carolina Highway Safety Research Center (HSRC) are teaming up with data specialists at Portland State University (PSU) to create a new dashboard that will allow users to see all the D.C. bike data together in one place.

Housed at PSU's Transportation Research and Education Center (TREC), BikePed Portal...

Navigating an unfamiliar place is uniquely challenging for people with disabilities. People with blindness, deafblindness, visual impairment or low vision, as well as those who use wheelchairs, can travel more independently in urban areas with the aid of effective wayfinding technology. A new report from the National Institute for Transportation and Communities (NITC) explores how to leverage low-cost methods to enable people to more easily move through public, urban indoor and outdoor spaces.

The study, led by Martin Swobodzinski and Amy Parker of Portland State University, used focus groups, two case studies, and an in-person structured wayfinding experience on the PSU campus to find the most helpful ways of getting around. Tactile maps were found to be a very useful resource, with an accessible mobile app also showing promise as an orientation and mobility aid.

The researcher will share more details about this project in a free webinar on December 15: Individual Wayfinding in the Context of Visual Impairment, Blindness, and Deafblindness.

How can relocating homeless services away from a downtown center change transportation patterns for people experiencing homelessness? Researchers Sarah Canham, Jeff Rose, Shannon Jones, Alannah Clay and Ivis Garcia of the University of Utah (UU) have published an article in the September 2022 issue of Health & Social Care in the Community.

The article, "Community perspectives on how decentralising an emergency shelter influences transportation needs and use for persons experiencing homelessness," offers evidence to support the need for no-cost transportation options for persons experiencing homelessness.

The findings draw on the ongoing project Understanding the Impact of Decentralizing Homeless Services on Transportation and Mobility in Salt Lake County, funded by the National Institute for Transportation and Communities (NITC).

Despite steady increases in homelessness in the U.S., only recently has research on transportation needs for persons experiencing homelessness been the focus of research endeavours. To fill this gap in the literature, the research team conducted a qualitative study in which 24 professionals working in planning, transportation, local government, and the homelessness services sector were engaged in in-depth, semi-structured interviews.

Researchers Ivis Garcia, Sadika Maheruma Khan, and Kevin Fagundo-Ojeda of the University of Utah with Miriam Abelson and Nicholas Puczkowskyj of Portland State University have published a new article in the November 2022 issue of Transportation Research Part D: Transport and Environment.

Scholarship on gendered mobilities has shown that women experience transit differently than men do, particularly regarding personal safety. The article, "Harassment of low-income women on transit: A photovoice project in Oregon and Utah," makes a unique contribution to this body of literature because it shows that women feel targeted also based on their racial or ethnic identity and not only their gender. The article discusses women’s actions every day to increase their sense of safety.

Research has shown that low-income women who are...

Researchers Jennifer Dill, Jiahui Ma, Nathan McNeil, Joseph Broach and John MacArthur of Portland State University have published a new article in the November 2022 issue of Transportation Part D: Transport and Environment. The open-access article, "Factors influencing bike share among underserved populations: Evidence from three U.S. cities," examines bike share use and interest among lower-income residents and people of color in New York, Chicago, and Philadelphia.

There is evidence that lower-income and people of color (POC) in the U.S. do not use bike share as much as higher-income and white people. Using data from residents living near bike share stations in New York, Chicago, and Philadelphia, the paper examines reasons for these disparities. Researchers looked at many factors that might explain bike share use and interest in lower-income, racially diverse, traditionally underserved neighborhoods. They focused on residents who live near bike share stations, so that proximity would not be a barrier.

A few key findings:

  1. People who are not members, but are interested in using bike share, including POC, are motivated to use bike share for fun, recreation, and social reasons (as opposed to utility).
  2. Knowledge of bike share and receiving information from interactive sources (for example,...

When the COVID-19 pandemic first swept across North America and led to emergency shutdowns during the spring of 2020, the way people acquired food and household necessities was dramatically impacted. As stay-at-home orders minimized personal travel, transit services were reduced and many stores and restaurants either closed or modified their operations. 

Some of the gaps were filled by online retailers and delivery services. However, access to goods and services varied substantially depending on people's age, income level, and ability.

A new multi-university study funded by the National Institute for Transportation and Communities (NITC), the U.S. DOT-funded university transportation headquartered at Portland State University, and the National Science Foundation (NSF) captured how households responded as local, state, and federal governments imposed and lifted restrictions, brick-and-mortar establishments closed and reopened, and e-commerce and delivery services adjusted to the changing conditions.

The findings of this research are critical for emergency planning, but also for understanding the ever-changing mechanisms used to access retail and service opportunities (whether in person or online). The research identifies opportunities for future interventions to remedy barriers to accessing food, which will...

Travel time reliability – or the consistency and dependability of travel times from day to day, and at different times of day – is a key metric that significantly affects people’s travel behavior. Since businesses rely heavily on transportation systems, an unreliable transportation network can also impact the economic competitiveness of urban areas. As such, reliable travel times are important for transportation agencies to promote economic stability within a community. Having accurate methods to evaluate reliability is important for both transportation practitioners and researchers.

A new report from Portland State University offers an improved method for determining the confidence interval of travel time reliability metrics. Researchers Avinash Unnikrishnan, Subhash Kochar and Miguel Figliozzi of PSU’s Maseeh College of Engineering and Computer Science used a highway corridor in Portland, Oregon as a case study to evaluate their method, and found that it compared favorably with other methods of evaluating the confidence interval of travel time reliability metrics.

"Traffic engineers can apply this method to come up with a range of estimates for the unknown true travel time reliability metric. The travel time reliability metrics calculated by traffic engineers and transportation planners will have variability due to factors such as road...
