The trip to and from school is made by nearly every child in Oregon every school day. Bike and walk buses, organized groups of school children, parents, and ride/walk leaders, seek to encourage biking and walking to school. A new research project at Portland State University's Transportation Research and Education Center (TREC) will gather information on bike buses nationwide, inspired by the success of Sam Balto's bike bus initiative at Alameda Elementary School in Portland, Oregon.

Balto, a physical education teacher, catapulted into the limelight in 2022 after establishing a weekly bike bus involving over 100 students commuting to school on two wheels. Its success and popularity prompted a broader initiative to understand and promote the benefits of bike and walk buses across the United States.

Researchers John MacArthur and Nathan McNeil, along with Evan Howington, a student in the Master of Urban and...

Would monetary incentives encourage more people to buy e-bikes? 

Portland State University (PSU) researchers are examining how purchase incentive programs can expand the current e-bike market, and the latest product to come out of this research is a white paper released earlier this month: “Using E-Bike Purchase Incentive Programs to Expand the Market – North American Trends and Recommended Practices (PDF)

The paper offers methods of identifying the most effective program structure for the incentive provider's priorities, and helpful information on how to administer and track the program.

For governments and clean energy advocates looking to encourage people to use e-bikes for transportation, a new online tool from Portland State University researchers offers an overview of the existing incentive programs in the United States and Canada.

The E-Bike Incentive Programs in North America table tracks e-bike purchase incentive programs and key details that can provide a point of reference for the development of future e-bike incentive programs and policies, or for further research on the topic. Read a recent article about the tool in BikePortland.

John MacArthur, researcher at PSU's Transportation Research and Education Center (TREC), led the development of the tool with the help of PSU transportation engineering masters student Cameron Bennett, a 2021 Dwight D. Eisenhower Transportation Fellow.

COMPARING TYPES OF E-BIKE INCENTIVE PROGRAMS

While the tracker shows a wide variety of approaches, Bennett identified Saanich, BC as demonstrating an especially...

When Portland State University student Marisa DeMull signed up for the summer 2014 study abroad course in the Netherlands, she wasn't necessarily looking for a new major. A civil engineering student, DeMull thought the summer program just sounded like a great way to get course credit.

DeMull learned that she could get six credits for the two-week program and applied immediately, a week from the deadline.

“I tried spreading the word. It’s the best program, and so few people really know about it, which is unfortunate,” DeMull said.

After two weeks in Delft and a series of lectures, bike tours, and eye-opening conversations, the PSU senior returned home to Portland State and declared a change in her program of study: she would now focus on transportation, a sub-field within civil engineering.

"Until this trip, I didn't really know that was a career choice," DeMull said. "I love riding bikes, but to design bike routes for a living? I met all these engineers who are completely devoted to bicycles, who just live and breathe it."

Practitioners give daily lectures to the students in the course, and...

OTREC researchers have done some work toward developing reliable standards for the use of recycled concrete aggregates in new concrete.
Making concrete out of recycled concrete aggregate, or RCA, can be a sustainable and cost-saving alternative to other aggregates. However, the quality of concrete made with RCA is dependent on the quality of the recycled material used. OTREC researchers Jason Ideker of Oregon State University and Jennifer Eisenhauer Tanner of the University of Wyoming, with graduate student researchers Matthew P. Adams and Angela Jones, sought to determine some of the primary concerns involved with the use of RCA and to arrive at methods of assessing its durability for use in new concrete.
 
Alkali-silica reaction occurs in concrete over time, causing it to expand and eventually weaken. There are standards for testing aggregate to determine its susceptibility to this reaction, but these testing standards were developed for traditional aggregates, not for RCA. Phase 1 of this research project involved accelerated laboratory tests related to assessing alkali-silica reactivity (ASR) of RCA. A team of four laboratories performed testing using the same materials to determine the variation between different laboratories.

John MacArthur, OTREC’s Sustainable Transportation Program Manager, was a panel moderator at this year's EVRoadmap 6 workshop.

The EV Roadmap workshop series has established itself as the Pacific Northwest’s premier electric vehicle gathering, with a goal of increasing the visibility and understanding of electric vehicles.

Co-sponsored by Portland General Electric and Portland State University, the event supports the shared goal of building a stronger, more sustainable transportation landscape.

The sixth annual EV Roadmap workshop, "Drivers Take the Spotlight," was a continuation of this fruitful partnership. The event was held at the World Trade Center in Portland on July 30-31, 2013. MacArthur moderated a panel titled "Not All Drivers Need Four Wheels." This panel focused on odd-sized electric vehicles such as e-bikes.

E-bikes are a specialty of MacArthur's; he has conducted several research studies about people's use and perceptions of the electric-assisted bicycle. His project "Evaluation of Electric Bike Use in Portland Metro Region" (click here for more information about that project, or to download the final report) focused on exploring the potential new market segments for e-bikes and the economic, operational, safety, and...

David Timm, P.E., the Brasfield & Gorrie Professor of Civil Engineering at Auburn University, traveled to Oregon in mid-March as part of the NITC Visiting Scholar program.

Timm is recognized nationally and internationally as a leading expert in the field of perpetual pavement, a sustainable approach to pavement design. He is also the author of a perpetual pavement design software, PerRoad. Engineers in this field have developed a pavement system that has the potential to last for up to 50 years, with only minor periodic surface repairs.

The visit, arranged by Oregon Tech’s NITC Executive Committee member Roger Lindgren, started with a March 13 PerRoad workshop in Salem. The workshop was attended by designers from industry and from the Oregon Department of Transportation (ODOT).

On March 14, Timm led another PerRoad workshop on the campus of Oregon Institute of Technology in Klamath Falls. Following the workshop was a presentation, focusing on perpetual pavement design and the advancements being made at Auburn’s National Center for Asphalt Technology (NCAT).

The Klamath Falls workshop was attended by 14 engineers and engineering students, with 53 people attending the presentation afterward.

Last week in Portland, family, friends, and colleagues gathered to remember one of Oregon’s most stalwart and effective public servants, Gail Achterman. Gail committed her life to furthering environmental and transportation issues to improve the quality of life in Oregon. Her commitment to improving and connecting transportation with land use and environmental policy was the reason she received the 2011 OTREC DeFazio Transportation Hall of Fame Award.

A fourth-generation Oregonian, Gail distinguished herself in law and natural-resource issues (as the Director of the Institute of Natural Resources at OSU) even before her involvement in transportation. As Chair of the Oregon Transportation Commission, Gail provided policy guidance to move the Oregon Department of Transportation (ODOT) toward a sustainable future. She has been instrumental in expanding the focus of ODOT beyond highways to include a complete multi-modal transport system.

Recognizing the importance of working smarter, not harder, Gail championed an aggressive program to advance Oregon’s sophisticated integrated models for transportation, land use and the economy. The program boosted efforts such as the GreenSTEP model to address greenhouse gas emission reductions, research into least-cost planning concepts...

Portland State University transportation engineering students added their expertise to a yearlong effort to help Salem reinvent itself. The Urban Transportation Systems class looked at options to improve bicycle and pedestrian travel in the city’s downtown core.

The effort is part of the Sustainable Cities Initiative, one of three OTREC-funded initiatives. The initiative, led by co-directors Marc Schlossberg and Nico Larco at the University of Oregon, chooses one Oregon city per year to make its classroom, directing coursework to help the city adopt sustainable practices.

This year is the first to include Portland State University’s participation. Students in assistant Professor Chris Monsere’s Civil Engineering 454 class gave presentations Nov. 29 and Dec. 1 on several alternatives to improve bicycle and pedestrian transportation and safety. Projects included:

  • Accommodating the bicycle and pedestrian crossing on Union Street at Commercial Street while considering impacts to automobile traffic
  • Connecting cyclists and pedestrians at the end of the Union Street path at Wallace Road
  • A bicycle and pedestrian route west of Wallace Road
  • Converting selected one-way streets to two-way operation
  • Traffic analysis of options drafted by bicycle advocates for the intersection of Commercial and Liberty streets at Vista Avenue
