PSU research delves deeper into ‘Four types of cyclists’

by on July 18th, 2012 at 2:08 pm

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.

Ride an e-bike? PSU researchers want to hear from you

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:

The quest for Oregon’s “Next Top (Transportation) Model”

High quality models are essential to making the right decisions about how we build our transportation systems. What do beautiful people have to do with transportation? Nothing! I’m talking about transportation models.

For instance, if your model includes motorized vehicle “traffic flow” as a fundamental component and barely includes bicycles or other modes, what do you think the outcomes from that model will be? Yep, you guessed it, more highways to accomodate more cars, and a tiny scrap or two left for bicycles. Unfortunately, that situation is one of the major problems in transportation planning today.

Geller, Dill talk bikes on ‘Green Science Oregon’

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…)

PSU evaluation finds that bike boxes work

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.

At TRB, wonks are celebrities (and they wear funny ties)

The Transportation Research Board is wrapping up their Annual Meeting in Washington D.C. this week. For the uninitiated, the TRB’s mission is to “promote innovation and progress in transportation through research.” Our own Elly Blue attended (along with about 11,000 others) last year and dubbed it the Great Transportation Convergence.

Not surprisingly, there was a big contingent from Portland at this year’s conference. The Portland State University based Oregon Transportation Research and Education Consortium (OTREC) sent a team of staffers to present their latest research and network with others in the field. (more…)

Scholarship helps PSU become hub of bike/ped research

BTA co-founder and Metro Councilor Rex Burkholder and his partner Lydia Rich (a public school teacher in North Portland) have made a commitment to Portland State University’s growing reputation as a hub for livable cities research.

In 2007, the couple established the The Rex Burkholder and Lydia Rich Scholarship. The $5,000 prize is awarded to a graduate student who “intends to be active in developing a future where bicyclists and pedestrians play a major role in the livability of urban areas.” (more…)

Agenda set for Transportation Safety Summit

by on September 30th, 2008 at 9:10 am

The City of Portland Office of Transportation will host the 2008 Portland Transportation Safey Summit next week (Monday, 10/8). The event is a great way to meet local and state transportation planners, policy makers, etc… and get information on many important resources and programs.

PDOT just released the agenda and program. Check it out: (more…)

I’ve still got a few notes and stories I’d like to share from my trip to the Pro Walk/Pro Bike conference in Seattle over the weekend.

On the last day of the conference, I asked a few members of the Portland delegation to share their most memorable new insights from the conference. Here are their responses:

Lynn Mutrie is the statewide youth education and outreach manager for the Bicycle Transportation Alliance (BTA): (more…)

PSU Prof shares results of bicycling behavior research

bicycling behavior?

How does the the built environment influence bicycling behavior? What routes do cyclists take? Will cyclists go out of their way to use bike lanes and other bike-specific infrastructure?

Those are the questions Portland State University professor Jennifer Dill has set out to answer. Dill — who teaches at PSU’s Center for Transportation Studiesembarked on a bicycling behavior research study back in January and last week she began to share some of her initial findings.

To learn more about where (and why) people ride, Dill attached at GPS unit on the bikes of 164 Portlanders for seven days. The participants logged over 1500 total bike trips. The GPS device recorded the purpose of each trip and Dill followed-up with an online survey to fill in missing gaps of information. (more…)
