OTREC was pleased to brief members of the Joint Policy Advisory Committee on Transportation on August 3, 2009. Staff provided an members with an overview of the OTREC’s research, education, and technology transfer programs. Students Nikki Wheeler and Nathan McNeil summarized their involvement in two projecs: “Investigation of Intersection Safety for Cyclists by Age and Gender” a “Evaluation of Bike Boxes at Signalized Intersections”. Additional faculty participated by providing a summary of their research focus.

Northeastern Universityís Peter Furth is known equally for his research in public transportation, bike planning and traffic signals. Furth brings his diverse interests to Portland for the holiday-shortened week of May 25th. On Tuesday, 5/26, there will be a seminar on his traffic signal priority work and on Wednesday, 5/27, there will be another seminar on his work regarding cycle tracks. In addition, Furth will have a variety of meetings with local transportation practitioners, including a bike tour by staff from the Portland Bureau of Transportation. The visit is co-sponsored by OTREC and IBPI. For more information about the seminars, visit PSU's Center for Transportation Studies.

Portland State University is committed to supporting research that is both regionally focused and globally relevant. This fall PSU has published a brochure featuring some of its exemplary research including OTREC sponsored projects by researchers Madeleine Pullman and Jennifer Dill. Dr. Pullman's research addresses the logistical issues raised by the rising demand for locally produced foods. She has studied supply chain success stories like that of Country Natural Beef, a cooperative family business committed to environmental responsibility, as well as other enterprises that have been slower to adopt such values, in order to better understand the impediments to change. Dr. Dill's research team has given GPS devices to bicycle commuters and collected rider surveys in order to collect data about the routes cyclists take, gender differences in riding and other information that can help cities better understand cyclistsí infrastructure needs. This regionally aimed research creates universal models of environmental responsibility and sustainability from which other cities can benefit.

On May 15, 2008, Jennifer Dill, Associate Professor in the Nohad A. Toulan School of Urban Studies and Planning and Director of the Center for Transportation Studies at Portland State University, participated in a congressional briefing in Washington, D.C. The briefing was sponsored by the Congressional Bike Caucus and the Active Living Research program of the Robert Wood Johnson Foundation on Biking Your Way to a Healthier Community. The Congressional Bike Caucus is chaired by Congressman Earl Blumenauer (OR) and Congressman Tom Petri (WI). Dr. Dill described her ongoing research of regional bike trips, tracked by GPS-equipped bicyclists. She notes that preliminary analysis shows that half of the bicycle riding happened on roads with bike lanes, off-street paths, or bicycle boulevards. She also briefly discussed policy implications and further research needs. Read Dr. Dill’s briefing here: Briefing.

Professor John Pucher, a car-less commuter from the Bloustein School of Planning and Public Policy at Rutgers University, was the first fall OTREC Visiting Scholar and CTS Seminar guest on September 28, 2007. His presentation, "Promoting Safe Walking and Cycling to Improve Public Health: Lessons from Europe," was standing room only, and the audience enjoyed his photos of bike-friendly features in cities across Europe. Pucher examined a range of public health impacts of our urban transport systems and argued that the current car dependence of American cities is responsible for enormous environmental harm, social isolation, lack of physical activity, and traffic dangers. He described how improving the convenience, safety, and attractiveness of walking and cycling in crucial to overcoming these negative impacts. Pucher discussed specific policies and programs used in Europe, and advocates their widespread adoption in American cities. A lively discussion with faculty, students and members of the Portland Bicycle Master Plan Committee followed the seminar.
Friday Transportation Seminars at Portland State University have been a tradition since 2000. We've opened up PSU Transportation Seminars to other days of the week, but the format is the same: Feel free to bring your lunch! If you can't join us in person, you can always watch online via Zoom.

Summary: Electric bicycles (e-bikes) are well established in China and other Asian and European countries but have yet to realize their potential in the United States, although recently the number of e-bikes has been growing. Research on the economic, operational, and safety issues of e-bikes in the U.S. is limited. This research aims in part to understand if different bicycling technology, in this case electric assist bicycles or e-bikes, can reduce barriers to bicycling and encourage more bike trips and longer bike trips, and increase the diversity of people bicycling, including people with a disability or chronic injury to bicycle. Some of these barriers include trip distance, topography, time, and rider effort. E-bikes typically resemble a standard pedal bicycle with the addition of a rechargeable battery and electric motor to assist the rider with propulsion. To answer these questions, we conducted an online survey of existing e-bike users on their purchase and use decisions. Results from 553 e-bike users across North America are analyzed here. Results suggest that e-bikes are enabling users to bike more often, to more distant locations, and to carry more cargo with them. Additionally, e-bikes allow people who would otherwise not be able...

Abstract: Findings will be presented on an evaluation of two innovative bicycle facilities installed in late summer and early fall 2009 in downtown Portland aimed at providing a more separated and comfortable experience for cyclists. The SW Broadway cycle track (near PSU) and the couplet of buffered bike lanes on SW Stark and SW Oak were evaluated to understand how they are functioning on multiple levels. Each facility involved removing a motor vehicle lane by restriping to provide additional roadway space to bicyclists. The facilities were evaluated after they had been in place for approximately one year. Data collected to support this evaluation consisted of surveys of multiple user groups for each facility type, and video data collected by the City of Portland Bureau of Transportation at intersections along each of the routes to understand the facilities' impact on traffic flow, operations and user interactions.

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.
