Jolene Liu, a senior from Westview High School in Beaverton, completed a successful internship with TREC this year. The internship was funded by IBM through the Saturday Academy's Apprenticeships in Science and Engineering (ASE) program.
Liu worked under the tutelage of TREC researcher Krista Nordback for two months, stringing up an impressive list of accopmlishments over that time. She worked to help create the online non-motorized traffic count archive, a centralized database for bicycling and walking count data. Liu tested the database structure, summarized data formats and wrote help text for future users. She also processed manual counts of pedestrians and cyclists from intersections in Bend, Eugene, Portland and throughout Oregon.
For an IBPI professional development course, Liu also calibrated pedestrian counting equipment and demonstrated the equipment for course participants.
Perhaps most impressively, Liu co-authored a paper accepted for presentation at the annual meeting of the Transportation Research Board this coming January: "Creating a National Non-motorized Traffic Count Archive: Process and Progress," Paper 15-5310.
"She was amazing," Nordback said. "She took on tasks most undergrads wouldn't have been able to handle, plus she took amazing notes at our (Technical Advisory Committee) meeting in Salem.
"She got to watch...Read more
OTREC researcher Miguel Figliozzi details some of the work on an Oregon Department of Transportation project, "Design and Implementation of Pedestrian and Bicycle Specific Data Collection Methods in Oregon," in this video produced by the Federal Highway Administration.
The project reviewed collection methods such as tube counters and loop detectors for accuracy and looked at using count numbers to deterimine average annual pedestrian and bicycle traffic at intersections.
Figliozzi was lead researcher on the project, with Christopher Monsere. Both are associate professors of civil and environmental engineering at Portland State University.
OTREC's Krista Nordback was also involved in the project, as were graduate students Pamela Johnson and Bryan Blanc. More information on the project is at:
Krista Nordback, an OTREC staff researcher, won the Outstanding Paper award from the Transportation Research Board's Bicycle Transportation Committee. The award honors Nordback's paper, "Measuring Traffic Reduction from Bicycle Commuting," which was also featured here:
The paper marked the first research to document a statistically significant drop in motor vehicle traffic during a bike-to-work event. The paper is available to download here or through the link above.
The award is given to the best paper submitted to the Committee on Bicycle Transportation for the 2014 TRB annual meeting, held Jan. 12-16 in Washington, D.C. The committee reviewed 85 papers, using anonymous peer reviewers and committee members.

The bicycle counts suggested that, on Bike to Work Day, more people did bike to work. But did fewer people drive?
OTREC staff researcher Krista Nordback took up the issue and will present her findings Monday, Jan. 13 at the Transportation Research Board’s annual meeting in Washington, D.C.
The bike count data from sites across Boulder, Colo., certainly impressed Nordback. “Bike to Work Day has this huge spike,” she said. “The bike counts double at a lot of the count sites.
“Wouldn’t it be cool if we could see something similar with the motor vehicle count data?”
In a twist that might only happen in Boulder, with its ample bike counters, Nordback had a harder time tracking down the motor vehicle counts. She lucked out, finding that the city’s red-light cameras had been counting cars alongside their primary job of catching red-light runners.
Those motor vehicle counts showed a consistent drop on Bike-to-Work days compared with average workdays in June and July. It was a small drop, but even finding that was unprecedented: no studies had documented a statistically significant drop in motor vehicle counts during any bike-to-work event.
