The role of walking in the development of healthy, livable communities is being increasingly recognized. In urban areas, intersections are often viewed as a deterrent to walking, as their operation primarily favors automobiles, leading to large and unnecessary delays for pedestrians. There is currently very limited research on accommodating and/or prioritizing pedestrians at signalized intersections in the North American context. Pedestrians are often considered as a deterrent to efficient vehicular traffic flow and therefore active efforts to include them in operational decisions at intersections have been lagging. This research aims to fill that gap by understanding factors that influence pedestrian crossing behavior at signalized intersections and developing cost effective and easily deployable signal timing strategies that could be employed at intersections, to increase efficiency for pedestrians.Read more
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

Abstract: A new way of measuring Level of Service for bicycles, pedestrians, and transit is planned for the next Highway Capacity Manual. Are these the right tools to help us plan and build the system we want? If not, what answers do these tools give us and how should we use them? This presentation will review the approaches to multi-modal Level of Service at the national and local levels and discuss efforts to validate the HCM methods. It will also cover the effect of our LOS policies on climate change and explore ways that we might tweak our analysis to get a more accurate picture of the transportation system for all users.
Bio: Seleta Reynolds plans, funds, and implements bicycle and pedestrian projects as a consultant for the Seattle office of Fehr & Peers. Seleta contributed to the national Safe Routes to School toolbox and has served as a guest lecturer on transportation planning for San Jose State University, Portland State University, and UC Berkeley. She serves on the Transportation Research Board Pedestrian Committee and as the President of the Association of Pedestrian and Bicycle Professionals. One of her favorite side projects was a collaboration with artists Steve Lambert and Packard Jennings to imagine the future of transportation for the Art on Market Street project in San Francisco. Prior to joining Fehr & Peers in 2001, she was the bicycle and...Read more

Abstract: As part of Clark County Public Health’s Planning Active Walkable Neighborhoods project, a Health Impact Assessment (HIA) was conducted on the county’s Bicycle and Pedestrian Master Plan. A rapid HIA was completed to provide input on the draft plan, and a subsequent comprehensive HIA was designed to evaluate the impacts of final proposals. This presentation will provide an overview of the process and results of the HIA, examine lessons learned, and discuss transferability to other jurisdictions or projects.

Abstract: Today, most streets are designed and managed to meet mobility standards that focus on the movement of motor vehicles, failing to adequately accommodate and prioritize transit, walking, and biking. A new culture of innovation is needed in transportation as traditional solutions alone will not suffice. By 2035, the Portland Plan envisions transportation facilities that are designed and managed to prioritize travel investments that improve walking, biking, and universal accessibility as the first priority.
In support of this vision, Peter Koonce, Manager of the City's Signals, Street Lighting, & ITS Division will discuss how he's looking to make the City's traffic signals consistent with these goals resulting in more effective integration of land use, transit, cycling, and walking. The discussion will be centered around research that is needed to improve our understanding of best practices from the U.S. and Europe for application in Portland.

Abstract: Walking and bicycling are being promoted as transportation options that can increase the livability and sustainability of communities, but the automobile remains the dominant mode of transportation in all United States metropolitan regions. In order to change travel behavior, researchers and practitioners need a greater understanding of the mode choice decision process, especially for walking and bicycling.
This presentation will summarize dissertation research on factors associated with walking and bicycling for routine travel purposes, such as shopping. More than 1,000 retail pharmacy store customers were surveyed in 20 San Francisco Bay Area shopping districts in fall 2009, and 26 follow-up interviews were conducted in spring and summer 2010. Mixed logit models showed that walking was associated with shorter travel distances, higher population densities, more street tree canopy coverage, and greater enjoyment of walking. Bicycling was associated with shorter travel distances, more bicycle facilities, more bicycle parking, and greater enjoyment of bicycling. Respondents were more likely to drive when they perceived a high risk of crime, but automobile use was discouraged by higher employment densities...Read more
