Roger Geller's chart that started it all.

It's been six-and-a-half years since Portland Bureau of Transportation bicycle coordinator Roger Geller first defined the "Four types of cyclists". Geller's insights proved to be groundbreaking and his definitions have stood the test of time. I frequently hear references about the need to attract more "Interested but concerned" riders at conferences all over the country and I read about them in articles in media large and small.

Now a noted bicycle researcher at Portland State University, Jennifer Dill, is working to learn more about the various types of riders. At the recent Velo-City conference in Vancouver B.C., she shared her research, Categorizing Cyclists: What Do We Know? Insights from Portland, OR (PDF). Now her work has been made public.

Researchers at Portland State University are looking for interview subjects for a project on e-bikes. Jennifer Dill, an associate professor at the Nohad A. Toulan School of Urban Studies and Planning, got in touch with us with the news.

Dill says it's a small, exploratory research project intended to further their understanding of the e-bike market and e-bike users. "This may lead to a larger study of the role e-bikes play in bicycle transportation."

Here's some text from a flyer to recruit interview subjects:

Science Oregon show.

CIty of Portland Bike Coordinator Roger Geller and noted PSU transportation researcher Jennifer Dill star in the latest episode of Green Science Oregon.

The 10-minute segment (watch it below) is a good primer on the current state of Portland's bike network. It's also a window into where Portland is heading in the future and how the city plans to reach their goal of 25% bike mode share by 2030. (more...)

A year-long evaluation by researchers at Portland State University's Institute for Bicycle and Pedestrian Innovation has found that Portland's bike boxes improve the safety of roads users on a number of levels. The research — funded through the Oregon Transportation Research and Education Consortium — complements another study from the University of Texas published last month that also found bike boxes to have a positive impact on traffic safety. City of Portland Bureau of Transportation officials say these studies confirm their own observations about the bike boxes and they are in the process of identifying new locations to add more of them.

Oregonian reporter Jeff Mapes has the scoop on an interesting Portland State University study:

"Jennifer Dill, an urban studies professor, wants to recruit a wide range of cyclists -- and lots of them -- to tote global positioning system units on their bikes for a 10-day period. She said researchers hope to learn whether cyclists go out of their way to use bike lanes and bicycle-friendly streets and to see how travel habits are affected by such factors as the weather.
