A research study released Monday by the National Institute for Transportation and Communities program offers the most comprehensive evaluation of protected bicycle lanes to date. The study, “Lessons from the Green Lanes,” examines recently installed protected bike lanes in five of the six founding PeopleForBikes Green Lane Project cities and provides the scientific basis for decisions that could improve bicycling in cities across the United States.
Protected bike lanes, sometimes called cycle tracks, are on-street lanes separated from traffic by curbs, planters, parked cars or posts to help organize the street and make riding a bike appealing for people of all ages and abilities. Because protected bike lanes are relatively new to the U.S., little academic research has existed to help leaders evaluate the risks and rewards of the investment in putting the facilities on the ground.
This study provides definitive evidence that people feel safe riding in protected lanes and that people traveling by car or foot also support building more protected lanes to separate bicycles and automobiles. It also provides insight on the safety, use and economic effect of protected lanes.

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,...
A project to create more miles of protected bike lanes in American cities, which launched this week, turned to OTREC researchers for the project’s research component. The Green Lane Project invited the researchers to Chicago for the project launch.
The Green Lane Project, a project of the Bikes Belong Foundation, chose six cities to serve as pilot sites for new designs and approaches to creating comfortable, separated bike routes such as cycle tracks, which may or may not be painted green. Being part of the project will enable the cities to share their experiences, get help with communication and coordinate with federal, state and local agencies.
The six cities are Austin, Texas; Chicago; Memphis, Tenn.; Portland, Ore.; San Fransicso; and Washington, D.C.
Portland State University researchers Chris Monsere, Kelly Clifton and OTREC Director Jennifer Dill went to Chicago for the launch and to meet potential research partners. They shared their research approach with representatives from the six cities.
After performing similar evaluations of bicycle facilities in Portland and Washington, D.C., the Portland State researchers are proposing to fine-tune and apply their methodology to the six project cities. The team would assess the safety, operations economic effects,...Read more
For rapid transportation mode-share changes, it’s hard to beat Kunming, China, where OTREC Director Jennifer Dill is visiting this week. In recent years, car and transit trips have quadrupled. Bicycling, which used to account for more than half of trips, now makes up less than a quarter.
Dill is with a team visiting Kunming as part of the PSU-China Innovations in Urbanization program.The visit is led by professor Connie Ozawa, director of Portland State University's Nohad A. Toulan School of Urban Studies & Planning (TSUSP), and includes: professor Yiping Fang; practitioner-in-residence Gill Kelley, former planning director of the city of Portland; Dean Marriott, city of Portland’s director of environmental services; and Jianhong Ye, a post-doctorate fellow at TSUSP.
The team participated in a workshop with over 50 planners from the region, sharing information on how Portland plans for sustainability. The visit is hosted by the Energy Foundation and the city of Kunming.
Like many cities in China, Kunming is facing tremendous growth pressures and increasing motorization. Between 1995 and 2011, car ownership went up from 20 cars per 1,000 people to 150 per 1,000. As a result, the...Read more

Topic: Trick or Treatment? Impact of Route-Level Features on Decisions to Walk or Bike
Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip?
Research to date has focused on either large-scale areal measures like "miles of bike lane nearby" or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike and walk accessibility along the most likely route for a given trip. The method is applied to travel data, and results provide new insight into the relationship between route quality and travel mode choice.
Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods that address protected bike lanes (aka “cycle tracks” or “separated bike lanes”), only conventional striped bike lanes, shoulders, and shared streets. There are other methods for predicting comfort from a bicyclist’s perspective that do consider protected bike lanes, but they are either based only on expert opinion or on surveys in Denmark.
This presentation will describe how to evaluate the level-of-service of a protected bike lane using results from surveys conducted in the United States. The model developed by this project could be used to supplement the current HCM to objectively consider a wider range...Read more
Summary: Cycling is on the rise across the U.S. and its popularity has grown beyond the usual leaders - Portland, OR, Seattle, WA, Davis, CA, Minneapolis, MN and Boulder, CO. New York City, NY Chicago, IL and Washington, DC are among those cities making significant investments in bike infrastructure in recent years and have realized substantial growth in people taking to the streets on two wheels. This presentation will summarize some results from our comprehensive assessment of the safety, operations, economic impacts, user experience, and perceptions of new protected bikeways in 5 cities U.S. cities (Austin, TX; Chicago, IL; Portland, OR; San Francisco, CA; and Washington, D.C.). To support this research, the team collected and analyzed 204 hours of video, 2,300 returned surveys of residents, and 1,111 returned surveys from people intercepted riding the new facilities.

Summary: In this seminar, Tara Weidner will discuss changes in the works to the State Analysis Procedures Manual (APM) to include three graduated levels of bike planning methods for use in Oregon communities, based on community size, data needs, and planning stage. These include the Bike Level of Traffic Stress (BLTS), a sketch tool used to assess bike network connectivity, the data-heavy Highway Capacity Manual Multi-modal Level of Service (MMLOS) procedures, and a simplified MMLOS developed by the same researchers.
Bio: Tara Weidner is an Integrated Transportation Analysis Engineer in ODOT’s Transportation Planning Analysis Unit (TPAU). She has over 20 years of experience in modeling and analysis of multi-modal transportation systems. Her work focuses on arming Oregon’s communities with tools to plan for the future, including being the lead on ODOT’s GreenSTEP Greenhouse Gas model and coordinating other multi-modal transportation and land use tools and analysis.
