MOBILITY BY E-BIKE STUDY

Share your trips with transportation researchers to grow knowledge about e-bike mobility and sustainability.

We're seeking e-bike users from all over the U.S. to join a new research project led by John MacArthur of Portland State University and Chris Cherry of the University of Tennessee, Knoxville. They're looking at the sustainability effects of e-bikes and utilitarian travel behavior of e-bike users, including origin, destination, route, time, speed, mode replacement, and trip purpose. Passively share your trips with us - just plug in a dongle, download our app, and ride like you normally do. The study is open to U.S.-based participants who ride an e-bike with a Bosch onboard computer, and use an iPhone.

HOW DOES THE STUDY WORK?

1) Instrumentation

Researchers developed a low-impact instrumentation platform that leverages and merges the unique capabilities of e-bike and smartphone sensors. This technology relies on communication between the e-bike and...

Gabby Abou-Zeid is pursuing her M.S. at Portland State University and working with Dr. Kelly Clifton's SUPER (Sustainable Urban Planning & Engineering Research) Lab. Her research has focused on walkability and pedestrian travel as well as intersections between transportation and land use. Walkable urban design is critcal for resilient cities. Research questions include: How often, and for what trip purposes, are Tucsonans walking as a transportation mode? Which built environment features promote walkability according to both Tucson residents and existing literature? Do the built environment characteristics identified actually impact travel behavior? In Tucson, walkable urban design could benefit or improve public health, pedestrian safety, thermal comfort, local economies, and social capital in addition to helping to reduce the city's carbon footprint.

Portland State continued our tradition of standing out at last month's annual gathering of the Transportation Research Board (TRB). We've collected some highlight stories as well as posters and presentations of Portland State University research presented at the conference. Explore the links below to see what PSU researchers brought to D.C. this year, and read about some student and faculty accomplishments at the nation's largest transportation research conference.

We've also collected our best photos—Check out our TRB 2020 photo album here.

Gabby Abou Zeid

Gabby Abou-Zeid is a first-year civil engineering graduate student, 2019 Eisenhower Fellow and recipient of the 2019 IBPI Rex Burkholder and Lydia Rich Scholarship. She is pursuing her M.S. at Portland State University and working with Dr. Kelly Clifton's SUPER (Sustainable Urban Planning & Engineering Research) Lab. She received her BS in sustainable built environments from the University of Arizona in 2019, and plans on pursuing a PhD in a transportation-related field after her master's program. Prior to coming to PSU, she conducted research with Dr. Clifton through the Transportation Undergraduate Reearch Fellow (TURF) program*. Gabby will present her work on the demand for freight at multifamily apartment buildings on February 14 in a Friday Transportation Seminar at Portland State.

Watch an interview with Gabby about her research at University of Arizona on Walkability in Tucson, Arizona.

Katherine Keeling is a first-year masters of science in civil engineering (MSCE) student and graduate research assistant for Dr. Miguel Figliozzi in civil & environmental engineering at Portland State University. Her research topics include bus-bicycle conflicts, e-grocery home delivery (as last-mile logistics), and the relationship between parking behavior and regulatory fines. This is the first in a series of student highlight videos showcasing student transportation research at Portland State University. This video series is created by PSU's Research and Graduate Studies department in tandem with our video series featuring TREC's faculty researchers, the first of which (featuring Dr. Chris Monsere) we released last month.

Watch the interview with Katherine Keeling.

Students on bikes in the Netherlands

In celebration of Portland State University's Day of Giving on December 3rd, we're devoting our efforts this year to raising funds in support of experiential learning opportunities through travel scholarships for transportation students.

TREC Experiential Learning Scholarships are part of a new initiative to broaden our student impact beyond our hands-on experience in research and support of PSU's Students in Transportation Engineering and Planning (STEP). We want to support immersive, experiential trainings outside of the Portland metro region. Introducing students to people and learning opportunities in other states and countries will allow them to bring innovative transportation concepts back to Portland, Oregon. This includes our flagship study abroad program: "Sustainable Transportation in the Netherlands" which will be held again this summer June 21 - July 4, 2020.
