Graduate student researcher Alex Bigazzi, of Portland State University, will present his work in Vietnam next week.

The Asia-Pacific Economic Cooperation (APEC) is hosting a transportation workshop in Ho Chi Minh city. The opportunity for Bigazzi to attend is the result of a spontaneous connection he made recently at a conference in Annapolis, Maryland, where he was giving a paper on truck-specific traffic management.

Large trucks contribute a large share of emissions, especially when traveling at a slow crawl through heavy traffic. Bigazzi’s work explores ways to mitigate the effects of this traffic congestion on air quality.

Bigazzi presented two papers at the 54th Annual Transportation Research Forum, which took place March 21-23 in Annapolis. One of them, “The Emissions Benefits of Truck-Only Lane Management,” offers a better understanding of the impacts of congestion on heavy-duty vehicles.

After a question-and-answer exchange, he was invited to present the same research in Vietnam’s largest city.

Portland State University inducted graduate student Kristina Currans into the Denice Dee Denton Women Engineers Hall of Fame in a ceremony Nov. 15. Currans is the second transportation engineering student to win the student award.

Maria Klawe, president of Harvey Mudd College, took the Outstanding Female Engineer honors.

Currans’ boundless enthusiasm and dedication to her work quickly become apparent to anyone who works with her, said Kelly Clifton, an associate professor of civil engineering and director of the Oregon Modeling Collaborative. “I’ve never met someone able to manage so many things,” said Clifton, who nominated Currans for the honor.

Currans works with Clifton as a part of the Oregon Modeling Collaborative and on several OTREC research projects. “She brings a tremendous amount of energy,” Clifton said.

After graduating Oregon State University with a civil engineering bachelor’s degree in 2010, Currans soon made a name for herself in transportation circles. She started her graduate coursework at Portland State and worked during academic breaks with the Oregon Department of Transportation’s Transportation Planning Analysis Unit, home to state and regional transportation models.

“For someone who had just graduated with an undergraduate degree, she completed that internship and really impressed ODOT,” Clifton said. “To do that so quickly caught everyone’s attention.”

Currans tested and worked with the Statewide Integrated...

Students and faculty researchers from OTREC universities will present 45 papers at the Transportation Research Board’s annual meeting Jan. 22 to 26 in Washington, D.C.

The papers, to be presented at 37 separate sessions and poster sessions, stem from transportation research at Portland State University, the University of Oregon and Oregon State University. The three universities will send 43 students to the conference.

Alex Bigazzi, a PSU engineering doctoral student, will present his work on topics including congestion and emissions at the conference. Some of that work stems from his master’s thesis, “Roadway Congestion Impacts on Emissions, Air Quality, and Exposure,” with adviser Miguel Figliozzi at PSU. The thesis won this year’s Milton Pikarsky Memorial Award, which will be presented Jan. 21 at the Council of University Transportation Centers awards banquet.

Bigazzi will present another paper, which he wrote with PSU’s Kelly Clifton and Brian Gregor of the Oregon Department of Transportation, that looks at fuel economy for alternative-fuel vehicles in congestion. Titled “Advanced Vehicle Fuel-Speed Curves for Regional Greenhouse Gas Scenario Analysis,” the paper helps Oregon DOT incorporate hybrid, electric and fuel-cell vehicles into its emissions planning model.

While traditional vehicles lose fuel efficiency during congested driving, advanced vehicles don’t suffer from the same effects, according to the paper.  Some even do better in...

Miguel Figliozzi, OTREC researcher, has been selected to chair a study group that will assist DEQ in developing a report, including recommendations for legislation regarding truck efficiency, reduced idling, and emissions. This report will be submitted to interim environment and natural resource committees of the Oregon Legislature by October 2010 for their consideration and any possible action during the 2011 legislative session. The 2009 Oregon Legislature adopted House Bill 2186, which directed DEQ to study potential requirements regarding the maintenance or retrofitting of medium- and heavy-duty trucks in order to reduce aerodynamic drag and otherwise reduce greenhouse gas emissions. DEQ also plans to study potential restrictions on engine use by parked commercial vehicles, including but not limited to medium- and heavy-duty trucks. Study group members will work with DEQ staff to report findings and recommendations for legislation to the interim legislative committees on environment and natural resources by October 1, 2010.
