Faced with fewer children walking or bicycling to school, governments and other groups have sought to reverse this decline. Even when there's money to address the issue, however, local governments and school districts don’t know how best to spend it to get more children on foot or bicycle.

OTREC researchers Lynn Weigand and Noreen McDonald stepped into this void with their project, “Evaluation of Safe Routes to School Programs: Qualitative and Quantitative Analysis of Parental Decision-Making.” Their final report is now available.

Existing research only scratches the surface of how parents decide which mode their grade school-aged children take to school. Weigand and McDonald explored the decision-making process with focus groups and tested a new Web-based survey to supplement the limited information gained from existing paper surveys.

Focus groups, in particular, can explain motivations more richly than can survey questions, Weigand said. Parents might select a single survey response, for example, to mean drastically different things.

“Parents cite ‘convenience,’ but that means different things to different parents,” Weigand said. “For some, it means it’s more...

When people talk about Portland, they talk about weather and bicycling. Judging by the Transportation Research Board annual meeting in Washington, D.C., researchers are looking into the same two things.

Bikes, of course, draw more interest at a transportation conference than in other circles. Here, Portland continues to draw attention: A single day’s poster session featured no less than seven papers that use Portland as a bicycle research laboratory.

The examination of bicycling and weather drew research looks from around the continent. A paper with authors from OTREC and the Institute of Transport Studies at Monash University, Australia, looked at how well different factors, including weather, affect bicycling in Portland, Ore., and Brisbane, Australia.

Light rain, for example, had little effect on bicycling in Portland, said Portland State University’s Miguel Figliozzi, one of the paper’s authors. The drop in ridership was four times as great in Brisbane on drizzly days.

“We’re used to light rain, so the difference is very small in Portland,” Figliozzi said. “In Australia, maybe they are not used to that.”

Geoffrey Rose of Monash University, another author on the paper, said the paper could help transportation decision makers understand and respond to effects of weather on active transportation, particularly as they deal with climate change. “This helps to understand the effects (of weather) on cycling today and what we can do to perhaps...

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...

The Initiative for Bicycle and Pedestrian Innovation has received a gift to support an annual transportation lecture at Portland State University. The gift, which establishes the Ann Niles Transportation Lecture Endowment, was finalized last month.

Created by Philip Niles in memory of his late wife, Ann, the endowment will bring a speaker each year to address transportation and planning issues for students, faculty and the community. Ann Niles was a strong advocate for livable neighborhoods and served on many transportation-related boards and committees in Portland.

Ann Niles grew up in Grants Pass, Ore., and graduated from Reed College in Portland, where she met Philip. She earned a graduate degree in library science from the University of Minnesota and began her career at the Carleton College library.

Ann and Philip retired in 1999 and returned to Portland. Ann developed a second career in urban development and transportation and worked with the city of Portland and the Pearl District Neighborhood Association. She chaired the Pearl District Transportation Committee for eight years, promoting better sidewalks and crosswalks for pedestrians and better bicycle routes and parking throughout downtown Portland. Ann also represented the Pearl District on the Portland Streetcar Citizens Advisory Committee and the advisory committee for Portland’s transit mall revitalization.
