Led by Xiaoyue Cathy Liu of the University of Utah (UU) and funded by the National Institute for Transportation and Communities, researchers have created a web-based modeling tool (see GitHub repository built for the Utah Transit Authority) that enables U.S. transit providers to explore the impacts of changing over their systems to electric buses*. The researchers ran the model for TriMet in Portland, OR as well, with TriMet results and analysis presented in the final report (PDF).

"The interactive visualization platform lets users explore various electric bus deployment budget scenarios, so that transit agencies can plan the most cost-effective way to transition their fleet from diesel to electric buses – while prioritizing disadvantaged populations," Liu said.

The research team, at University of Utah, Portland State University (PSU), and University of California, Riverside, set out to answer three questions: 

  1. What costs and benefits are associated...

The National Institute for Transportation and Communities (NITC) is proud to introduce a new dissertation fellow: Kelly Rodgers of Portland State University. Four other NITC dissertation fellows were announced in summer 2020. Our NITC Dissertation fellowships applications are accepted on a rolling basis. 

Kelly’s dissertation project will focus on "The use and influence of health indicators in transportation decision-making."

Research on health and transport has increased significantly in the past 20 years, both across health and transportation fields. Researchers and practitioners have called for the use of health indicators in transportation, which come amidst the growing emphasis on the use of indicators for transportation plans and projects in general. The underlying hope is that new procedural arrangements, such as measuring and tracking indicators, can turn policy goals into practice. This research project will explore the use and influence of health indicators in transportation using a mixed methods approach.

Research Team Lead: Christina Fink, Toole Design Group
Portland State Investigators: Christopher Monsere, Nathan McNeil and Sirisha Kothuri

One of the most common locations for motor vehicle-bicyclist crashes is at controlled intersections. Particularly dangerous is the conflict between through bicyclists and turning drivers (either left or right). Despite widespread acknowledgement of this problem, transportation engineers and planners still lack definitive guidance on how to safely and effectively design for bicyclists at intersections in the United States.

In a newly contracted project, awarded to Toole Design Group by the National Cooperative Highway Research Program (NCHRP), a team of researchers will identify design best practices to reduce conflicts at intersections. In addition to Toole, the team includes researchers from Portland State University, Oregon State University (David Hurwitz), and Safe Streets Research & Consulting (Rebecca Sanders). Christopher...

Each year, the Portland Chapter of WTS bestows scholarships to assist exceptional women in their educational pursuits in the field of transportation. The scholarships are competitive and based on the applicant’s specific goals, academic achievements, and transportation related activities. Two of the five 2020/2021 scholarship awardees are Portland State University students! WTS Portland will be celebrating all of the awardees during an online happy hour on Wed, January 27th at 5PM (PT) - RSVP here.

In recent years, there have been over 600 bicyclist fatalities annually in the United States. This sobering statistic has motivated a number of recent studies, including the recently released National Transportation Safety Board study, “Bicyclist Safety on US Roadways: Crash Risks and Countermeasures (PDF). ” That report notes that midblock crashes account for a disproportionate number of bicyclist fatalities and severe crashes, and that separated on-street bicycle facilities may reduce the likelihood of these crashes. However, there are only limited data on the safety outcomes of separated on-street bikeways in the U.S., despite their increasing popularity...

Cyclists ride along a bicycle boulevard in Portland, Oregon
Wei Shi, Portland State University

In active transportation research, plenty of attention has been given to how different types of bike infrastructure affect people's likelihood of biking. Research has demonstrated that protected bike lanes encourage more people to bike than simple painted lanes, and that most cyclists feel safer riding through a protected intersection as opposed to navigating shared space with cars. However, relatively few empirical studies have investigated how holistically connected an entire bike network is, and how different populations can be positively or negatively impacted in their decision to bike by that level of connectivity.

Wei Shi, a recent Portland State University graduate with a PhD in urban planning, wrote her doctoral thesis on...

Orange e-scooters on the road in Portland, Oregon
Michael McQueen, Portland State University

Is shared micromobility the ideal first/last mile supplement to transit? Can electric scooters make it easier for historically disadvantaged populations to get around? In just three years, brand-new fleets of e-scooters have substantially disrupted and altered the urban mobility landscape. For proponents, it's tempting to view them as a new answer to old problems. A just-released study finds however, that while there is potential for improved mobility if they are paired with other interventions, the shiny rows of e-scooters parked around cities aren't a catchall solution for our longstanding issues.

Portland State University (PSU) graduate Michael McQueen surveyed nearly 2,000 PSU students in his masters thesis, "Comparing the Promise and Reality of E-Scooters: A...
