Who bikes?

Who bikes? pie chart

From April 2011, via Sightlines Daily, using data from John Pucher and Ralph Buehler, who got it from the 2009 National Household Travel Survey.

Contrary to popular convention, the biggest share of bicyclists isn’t yuppies, it’s low income people. In fact, the lowest-earning quarter of Americans make nearly one-third of all bike trips. Among that group, I would expect to find at least some fraction of working poor, students, the unemployed, and retired people of modest means. No doubt there are almost as many reasons to bike as there are cyclists, but it’s clear that bikes are a favored choice among those on a budget.

The big takeaway for me, however, is looking beyond low-income riders. Bicycling is remarkably evenly distributed among the remaining three quartiles. With the exception of the over- represented bottom quartile, bike trips don’t appear to be the province of any one income class more than any other.

Last minute vote on bicycle data visualization project

November 28, 2011 / / 0 Comments

The United States Department of Transportation is holding a data visualization competition and Chicago bike crash locations are one of the topics.

From Michael Carney:

I started this project because, basically, I thought it would be interesting to make a map of bike crash locations around Chicago and present it to my GIS class at UIC. Sebastian Lew and I collaborated for several months and it evolved into something more. Using ArcGIS, we were able to symbolize streets by level of overall crash intensity, calculate crashes per mile on streets, perform hot spot analysis to identify areas with high numbers of crashes, compare ridership levels with crash levels, examine temporal trends in crash activity, and perhaps most importantly, assess the effectiveness (at least at a basic level) of current bicycle infrastructure. At the very least I hope our project can help you plan a safe route to work, at the most I hope it can be used by policymakers and planners when considering how and where to expand Chicago’s bike infrastructure.

Vote today only. View the project.

What downtown means

Not the guy from the story. 

I was “downtown” photographing situations that make it hard to walk (hard to be a pedestrian) on Sunday, November 13, 2011. While waiting for the light at LaSalle and Adams, a man wearing a Bears jersey in the front passenger seat of a taxicab asked me if I had pizza in my Yuba Mundo’s Go-Getter bag.

“No”, I said, adding, “It has my backpack in there”.

“It’s a very large bag”, he replied.

Realizing that he was sober and that we could hold a conversation, I explained, “It holds a lot of groceries”.

“Oh, you live downtown”, he ascertained.

Not quite. “I live a few miles outside of downtown”.

The light turned green and the driver moved on, but the guy left me with, “Have a nice day”. I said, “You, too”.

After I got home and was looking through my photos and recounted this story, I  realized that to him, “downtown” meant the entire City of Chicago. To me, downtown meant the Loop community area and some surrounding blocks. I might define “downtown” as a place bounded by Kennedy, Division, Lake Michigan, and Roosevelt. But to this suburban football fan, downtown is that big place that one has to travel a ways to get to. I remembered that I had the same understanding of downtown when I lived in Batavia, Illinois, a suburb 40 miles west of Chicago. You can access it by driving on I-290 and I-88, or by taking the Metra UP-West line to Geneva.

There’s at least one other assumption I can make from this conversation: If I shop for and carry groceries on a bicycle, I must live in Chicago; people in the suburbs are never seen shopping for and carrying groceries on a bicycle.

Another photo from my photo mission on Sunday. It’s Roosevelt University’s vertical campus building on Wabash and Van Buren. 

Cycle mapping

What are the sites that will let you either draw or upload a bike route to share with others?

And what are the sites or mobile apps that give you cycle routing?

A screenshot of Bike Share Map: London, UK.

And other bike-related maps?

I’m just simply researching and collecting links to cycling-related map mashups and apps.

So that bike lane enforcement

October 16, 2011 / / 0 Comments

Where is it?

This is beginning to make me angry.

The Chicago Police Department has issued 5 citations so far this year to drivers parking in the bike lane (well, as of October 11, 2011). I’ve taken photos this year of more than 5 drivers parking in the bike lane. Here’re frequencies from all the years I asked about*:

  • 2007 – 2 citations
  • 2008 – 6
  • 2009 – 8
  • 2010 – 2
  • 2011 – 5

At the September 2011 Mayor’s Bicycle Advisory Council, Chicago Department of Transportation Commissioner Gabe Klein said that he’s working on an enforcement plan. I’d like that plan to start with more frequent enforcement of Ordinance 9-40-060 – Driving, standing or parking on bicycle paths or lanes prohibited.

A blocked bike lane can make cycling more uncomfortable and dangerous, especially for inexperienced cyclists who often don’t change lanes in a visible and safe way.

*I’m only asking for 2007-2010 because I want it to coincide with the crash data I have.
