With the emergence of electric vehicles (EVs) as an environmentally friendly alternative to the internal combustion engine, OTREC researcher Robert Bass decided to investigate some of the uncharted effects of their growing prevalence.

Bass is interested in measuring and understanding the impacts that electric vehicle charging stations have on their cities’ power distribution systems.

Electric Avenue, located on the Portland State University campus where Bass is an associate professor, is the perfect research opportunity: a row of EV charging stations along Southwest Montgomery Street, between Broadway and Sixth Avenue in downtown Portland, Ore.

Launched in August 2011 as a joint project by Portland General Electric, PSU and the City of Portland, Electric Avenue is intended as a research platform for understanding the impact EVs have within the larger context of the city.

Nonlinear loads such as EV chargers can introduce power quality issues to a city’s electricity distribution system. Bass, with PSU undergraduate student Nicole Zimmerman, set out to measure the power quality effects of EV chargers along Electric Avenue.

Power quality manifests in several ways; for this study, the researchers focused on...

OTREC research associate John MacArthur, in partnership with Drive Oregon, has been awarded a grant from Metro.

The grant is part of a $2.1 million effort by Metro to improve air quality and community health.

With the Metro grant, Drive Oregon and MacArthur plan to conduct a study of consumer perception and use of electric bicycles, pedal-bikes that provide extra propulsion from a rechargeable battery.

The idea is to see whether having the use of an e-bike will persuade non-bicycle-commuters to use a bike for the “first and last mile” of their daily commute; for example, to get from their workplace to the nearest MAX light rail station.

The e-bikes provided in the study will be foldable for convenient carrying onto the train. Ultimately, the partners of this study hope to increase the percentage of people who commute by bicycle and light rail, thus contributing to overall community health by reducing automobile emissions.

30 e-bikes will be loaned to 180 employees of Kaiser Permanente, at three designated work locations. Each participant will have the free use of an e-bike for one month, bookended by surveys about their expectations and perceptions of the experience.

MacArthur is conducting some overlapping research into e-bike use in a related OTREC...

OTREC has announced eight winners of the “Small Starts” grant program, which launched last December. These grants, made available through a new OTREC initiative, were intended to fund small projects related to transportation and community development. Any eligible professor at Portland State University, Oregon State University, the University of Oregon, or the Oregon Institute of Technology was invited to apply for a grant.

Priority was given to tenure-track faculty who are untenured, and faculty who have not received an OTREC grant in the past. The Small Starts program was conceived for the benefit of researchers who want the chance to undertake a small project that supports innovations in sustainable transportation through advanced technology, integration of land use and transportation, and healthy communities.

A total of $60,000 was available to be awarded; with no individual award larger than $10,000.

Interested faculty turned in their proposals by January 31, 2013. Here are the winners:

  • Burkan Isgor, Oregon State University:

“Cracking Susceptibility of Concrete Made with Recycled Concrete Aggregates”

  • Donald Truxillo, Portland State University, partnered with ODOT:

“Evaluation of ODOT's Ecodriving Program”

  • Bob Bass, Portland State University, partnered with Drive Oregon:

“Impacts of Electric Vehicle Charging on Electric Power Distribution Systems “

  • Nancy Cheng,...
