Bicycle and pedestrian safety has emerged as a top priority for U.S. Transportation Secretary Anthony Foxx and the Department of Transportation. With this in mind, the department’s top research official visited Portland State University, home to the U.S. DOT-designated national center for livable communities.
Greg Winfree, the assistant secretary for research and technology, visited Portland State’s transportation research and education center June 13. Center Director Jennifer Dill and researcher Christopher Monsere gave Winfree a tour of the center’s living laboratory: Portland’s active transportation infrastructure.
Winfree, an advocate for improving safety for vulnerable road users, explored the city’s various bicycle safety efforts, including bike boulevards, protected bike lanes, bike boxes, bike-specific signals and signage. He also learned of pedestrian research involving traffic signals, crossings and modeling.
The tour highlighted research projects funded through U.S. DOT’...Read more
The NITC program's executive committee has selected a new roster of projects for funding under the National Institute for Transportation and Communities, or NITC, program. The committee chose 10 projects, totaling $900,000, under the NITC theme of safe, healthy and sustainable transportation to foster livable communities.
The projects are national in scope and reflect priority areas including transit supply and outcomes, and pedestrian and bicyclist behavior.
Projects selected include:
- A bicycle and pedestrian miles traveled project for Washington state.
- A study that measures the effectiveness on social media on advancing public transit.
- A look into crowdsourcing the collection of data on transportation behavior.
- A national study of Bus Rapid Transit outcomes.
A complete list of projects and principal investigators is below:
- National Study of BRT Development Outcomes: Arthur Nelson and Joanna Ganning, University of Utah
- Crowdsourcing the Collection of Transportation Behavior Data: Christopher Bone, Ken Kato and Marc Schlossberg,...
OTREC at Portland State University welcomed Eva Heinen of the University of Groningen, The Netherlands, for a special seminar June 18. Around 40 people attended the presentation, held at the Intelligent Transportation Systems Laboratory and titled “Cycling in the Netherlands and Multi-Modality.”
Eva Heinen is assistant professor of infrastructure planning and mobility at the Department of Spatial Planning and Environment, Faculty of Spatial Sciences, University of Groningen. She earned a Ph.D. from Delft University of Technology in 2011 focusing on bicycle commuting.
Many people in Groningen and The Netherlands as a whole combine transit and bicycling for trips. A typical configuration involves cycling from home to a train station and then renting another bicycle to reach the final destination, Heinen said.
Few people take bicycles on transit, Heinen said, and buses don’t offer bike racks or other accommodations. Folding bikes, whose compact size allows for portability, are one exception, Heinen said. Electric-assist bikes are also popular, particularly with older people.
Heinen has published many papers on cycling in international and national journals and has a large international network in cycling. She spent three months at the University of California in Davis as a visiting scholar. She is a member of the editorial board of Rooilijn, a Dutch journal for science and policy in spatial planning; a member of the Bicycle Committee; co-chair of the...Read more
Even as Portland racks up bike-friendly honors, ongoing research at Portland State University is shedding light on a new travel option that promises to get even more people on two wheels. Electric-assist bikes, or e-bikes, could hold the key to increasing cycling, particularly among women, older adults and people with physical limitations.
Portland State researchers Jennifer Dill and John MacArthur are exploring people’s perceptions and attitudes toward e-bikes and evaluating their use to see if these bikes encourage new cyclists. This spring, they’re loaning out locally made, GPS-equipped e-bikes to 120 people to learn about people’s actual experience using the bikes, marking the first time such research has been done in the country.
The research also includes a survey on e-bike use, which will help others understand the potential market. People who have ridden e-bikes can participate in this research by taking the survey at tinyurl.com/e-bike-survey.
E-bike use is increasing in North America, with many people switching from private cars and others using e-bikes to keep cycling as they age or after an injury. Increased use brings increased scrutiny, and efforts are already underway to limit where e-bikes can go and who can ride them. Many states require e-bike riders be licensed, set age limits or both.
Some local regulations prohibit e-bikes on bicycle and pedestrian paths. The city of Toronto,...Read more
OTREC research associate John MacArthur, in partnership with Drive Oregon, has been awarded a grant from Metro.
The grant is part of a $2.1 million effort by Metro to improve air quality and community health.
With the Metro grant, Drive Oregon and MacArthur plan to conduct a study of consumer perception and use of electric bicycles, pedal-bikes that provide extra propulsion from a rechargeable battery.
The idea is to see whether having the use of an e-bike will persuade non-bicycle-commuters to use a bike for the “first and last mile” of their daily commute; for example, to get from their workplace to the nearest MAX light rail station.
The e-bikes provided in the study will be foldable for convenient carrying onto the train. Ultimately, the partners of this study hope to increase the percentage of people who commute by bicycle and light rail, thus contributing to overall community health by reducing automobile emissions.
30 e-bikes will be loaned to 180 employees of Kaiser Permanente, at three designated work locations. Each participant will have the free use of an e-bike for one month, bookended by surveys about their expectations and perceptions of the experience.
MacArthur is conducting some overlapping research into e-bike use in a related OTREC...Read more

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 to bike because of physical limitations or...Read more
Over the last couple years, electric bicycles (e-bikes) have been gaining momentum. E-bikes may play an important role in addressing cities’ transportation and public health problems by getting more people out of cars and onto bicycles. But as the number of users increase, so too will potential conflicts (actual or perceived) with other road users, causing policy questions to arise.
The current state of e-bikes regulation varies dramatically across state and local jurisdictions, causing confusion. The confusion stems from the wide variety of devices and technologies on the market, perceived overlap of legal entities’ jurisdiction over the device, outdated or absent laws and regulations, and inconsistency of terms used to describe e-bikes. This confusion creates uncertainty for manufacturers and dealers and makes riders wary of embracing e-bikes.
One of the biggest concerns people have about e-bikes and their use, especially on shared-use paths, is speed....Read more
