Bike To Work Days have a positive correlation with cycling rate

Today is Winter Bike To Work Day in Chicago at Federal Plaza. If the results below are true, we should hold this event weekly during the winter! Held on January 20th to celebrate the coldest temperature on record, in 1985.

I was looking for research on why more people don’t ride bikes, or why they don’t ride bikes more often. I started my search on Professor John Pucher’s website at Rutgers University and found this about Bike To Work Days and other promotional events.

There is some evidence that BWDs increase bicycling beyond the event. The number of “first time riders” has increased in many programs: in Seattle, from 845 new commuters in 2004 to 2474 in 2008; in Portland, from 433 in 2002 to 2869 in 2008 (LAB, 2008). In San Francisco in 2008, bicycle counts at a central point were 100% higher on BWD and 25.4% higher several weeks later; bicycle share was 48.3% before BWD, 64.1% on BWD, and 51.8% afterwards (LAB, 2008). In Victoria, Australia, 27% of first time riders on BWD were still bicycling to work 5 months later (Rose and Marfurt, 2007).

Read it on page 8 of this PDF. I thank John for distributing all of his work for free online so that those without expensive journal subscriptions (or those who lost it by graduating college) can read the latest in bicycle research.

Here’s me surveying an attendee at the 2009 Bike To Work Day Rally in Chicago’s Daley Plaza. The results of the surveys taken each year by the Chicago Department of Transportation are not published.

Update on GIS information for Haiti

We all woke up this morning to see news that another earthquake has happened in Haiti, near the center of the first one eight days ago.

“The United Nations Development Programme (UNDP) employed nearly 400 Haitians in cash-for-work activities to jump start the local economy and facilitate the delivery of urgently needed humanitarian assistance.”

This post is an update to my previous article about how GIS is used for disaster relief efforts. I recently came across a webpage on Harvard’s China Earthquake Geospatial Research Portal that lists copious, up-to-date, GIS-compatible data from organizations around the world. The portal began in response to the Sichuan, China, earthquake in May 2008.

Visit the Haiti GIS Data Portal now.

For new GIS students, this would be a great starting point for a class final project. The Portal is hosting the datasets as a public service and invites anyone with relevant data to submit it to the site operators for wider dissemination. Data comes from the United Nations, several universities, OpenStreetMap contributors, and the German Center for Air and Space Travel, among others.

“Petty Officer 3rd Class Cameron Croteau, a Damage Controlman aboard the Coast Guard Cutter Oak, carries an injured Haitian girl to an awaiting Coast Guard HH-60 Jayhawk helicopter Tuesday, Jan. 19, 2010. Coast Guard and Navy helicopters airlifted injured Haitians to a private hospital in Milot, Haiti. U.S. Coast Guard photo by Petty Officer 3rd Class Brandyn Hill.”

As I mentioned in the previous post, there are many photos on Flickr when you search for “haiti earthquake.” When I wrote the post on January 14, 2010, there were only about 300 photos, and now there are over 6,900. Only 1,200 have a Creative Commons license, though (both of the photos above have a Creative Commons license). It seems that the United States Military, the United Nations, and major relief organizations are providing the majority of photos. And they’re uploading them fast. The number of photos on Flickr jumped by 50 from when I started this paragraph.

Helmets, hygiene, hair… help?

I subscribe to a Google News feed for “bike parking” where I find many articles about grander issues but they get caught in the search. When people talk about increasing or improving bicycling, they almost always talk about parking (it’s a necessity). A recent article talked little about bike parking; The short blurb about a hygiene “problem” of helmet hair piqued my attention.

A bicyclist on her first commute by bicycle wears a helmet in San Jose, California.

Helmets

As DOTS pushes biking, gender gap persists” (by Lauren Redding in the Diamondback, student newspaper from University of Maryland). DOTS is the University’s Department of Transportation Services, which has a goal of 9% of students getting to campus by bike and recently conducted a count that found only 20% of biking students are female. The article cites DOTS as saying that safety and hygiene are the major barriers that keep the frequency of women bikers low. Somehow, hygiene is related to helmet hair.

Helmet hair is not as important as building safe bicycling routes to the school, educating students on how to ride safely and locking their bikes correctly. The article in no way describes the University’s Transportation Services group as “helmet pushers,” but this comment bothers me: “For women especially — when you put on a helmet, you mess up your hair.”

Let’s stop building bike lanes and deal with this, stat! Okay, for real: There is a gender gap, but dealing with helmet hair will never match the effects of making cycling safe (or normal) on increasing the number of women who bike.

After I began an obsession with Dutch bikes and bicycling “culture” (a culture of safety and high numbers riding bikes), I learned more about helmets and the reasons people use them. My position about wearing and promoting helmets has changed somewhat, but my behavior, so far, hasn’t. Rarely does a Dutch person wear a helmet. From the research:

In the Netherlands, a survey of pediatricians found that 94% never wear helmet, but that 82% agree that helmet use should be advised for children (source). Overall, “less than 1% of adult cyclists wear helmets, and even among children, only 3–5% wear helmets” (source: “Making Cycling Irresistible” [PDF], the best article describing bicycling in the Netherlands, Germany, and Denmark, comparing it to countries with low bicycling rates, United States, United Kingdom, and Australia).

I bought this new helmet in Summer 2009, to be more comfortable and to look better. Like I said, my position has changed, but my behavior hasn’t. I think everyone should make their own decision about helmets; helmets are only useful to prevent head injuries once a collision or crash has occurred. It’s more important to build facilities and educate people to reduce the likelihood of a collision or crash.

My Dutch fixation continued to the end of the last semester – I presented and wrote a paper for my Sustainable Development Techniques class about what makes bicycling in the Netherlands safe and easy, and how the United States can learn. Dutch bicycling presentation for class (PDF) and the Dutch bicycling presentation for class (DOC).

The bike helmet-American relationship is amusing. I can’t explain it as eloquently as Mikael Kolville-Anderson in Copenhagen: he mentions it a hundred times (search of Copenhagenize for the term “helmet”). The latest news, although not about America, but relatable: Israel is getting ready to repeal part of the all-ages helmet law, which is seen as discouraging bicycling in the country.
