Best ways to present bicycle crash data

December 8, 2010 / / 0 Comments

I started some preliminary work on my crash reporting tool. I haven’t written any code, but I’ve been working on the logistics of analyzing and presenting the data to the public.

I obtained bicycle crash data for 2009 from the Illinois Department of Transportation’s Division of Traffic Safety. I’m not able to distribute raw data (you’ll have to ask for it yourself) and Illinois statutes prevent me from distributing personally identifying data (but it’s really hard to know what this is). In the meantime, based on Ben Sheldon’s suggestion, I loaded some of the data into a private Google Fusion Table that instantly maps geocoded data (it can also geocode the data for you).

Richard cautions me about way I choose to present data. I need to choose terms and descriptions carefully to avoid misinterpretations. Pete from the Boston Cyclist’s Union recommends against accepting self-reported data. I’ll be taking their advice into consideration as I move forward.

You see in the map (top) that a lot of crashes happen on Milwaukee Avenue (above). That’s where a lot of people ride (over 3,000 in 24 hours in the fall).

I have not begun to review the narrative details in the crash reports. Actually, they’re not very narrative because they’re fixed responses – no free writing allowed. And not every record represents a collision (meaning a crash with at least two parties). Many are self-crashes (is that a legit phrase)?

I’m not sure exactly what story I want the data to tell so it will probably be a while before I make anything public. One of my favorite geographic information books, Making Maps, talks about the endless ways maps can be designed and portrayed and that each tells a different story. It’s best if I know the story (a goal) ahead of time.

Chicago Flame reports on the recent UIC mayoral candidate forum

December 7, 2010 / / 0 Comments

Alyssa Cherwak writes in the Chicago Flame, the University of Illinois at Chicago’s student newspaper. Obviously, someone took better notes than I did. She’s got the real dirt for us, quoting the candidates for mayor throughout the article :

“What are the qualifications to be mayor of the city of Chicago?” asked Ryan Graves. “Be eighteen years old, a registered voter, a city resident, in no debt to the city, and no felony convictions. I meet all of these qualifications.”

After the forum, Danny Davis and Miguel del Valle started talking to reporters.

Olgivanna Lloyd Wright had the right idea

According to my tour guide at Taliesin West in Scottsdale, Arizona, it was Frank Lloyd Wright’s third wife, Olgivanna, who suggested that he open a studio in a warmer state as a place to spend winter. (His winter studio is in Spring Green, Wisconsin.)

Our wonderful tour guide. She graduated from the School of the Art Institute of Chicago.

Another case for integrating biking and transit

December 3, 2010 / / 0 Comments

Integrating biking and transit can reduce a user’s transportation costs.

A friend just instant messaged me to describe his “bike instead of transit” commute,

“I spent $440 on Chicago Transit Authority (CTA) this year and $300 on bike stuff. When I was just taking the CTA it was $1032 per year. I used to have the monthly pass deducted from my paycheck, $86 per month. Now I pay as a I go, and I go much less.”

In some places, and for other people’s situations, commuters could bike TO the train or bus and reduce their costs by eliminating a transfer. Transit also lengthens a bike rider’s possible trip distance when they combine the modes. In this sense, providing services or facilities for people riding bikes attracts new customers or maintains relationships with existing customers.

The Department of Transportation is now funding projects that improve bicycling (and walking) connections to bus and train stations. We should continue focusing on expanding and improving our bikeway networks by connecting them with our transit networks. By doing so, we make each system more robust and give people more options to choose the route that’s best for them.

Don’t vote for this guy

Will the next Chicago mayor be the same kind of urban planner like Richard M. Daley was? Will they build new parks and libraries at the same time they sell off infrastructure at a fraction of its value or abuse Tax Increment Financing funds?

I attended the UIC mayoral candidate forum on Wednesday to find this out. There was some talk about creating an open and transparent government (Patricia Watkins), with budgets that a 5th grader could read and spending denoted for each Ward or Community Area (I really like these ideas).

One candidate, Fredrick White, wants to support the building of a water bottling plant that would bottle water with “CHICAGO” on the label and have it sold in local stores and restaurants in order to create jobs (I don’t like this idea at all).

Fredrick K. White is probably telling the audience to visit his website.

I liked Miguel del Valle’s responses to the question about paying for higher education and ensuring the University of Illinois is funded. He recommended better integrating the community colleges and supporting the 3+1 program, where the final year of a bachelor’s program is completed at a university.

At least two candidates want to create technology parks, one even saying he wants Chicago to become the Silicon Valley of the Midwest. Another said Chicago can become the hotbed for nanotechnology development (William Walls).

Whatever was said, it wasn’t said by Fenton Patterson. I can’t recall anything he said. When responding to questions, he swaggered to the front of the stage, pulled his jacket back, stooped his head down, mumbled something that didn’t answer any question that was asked. His demeanor looked like that of a detective on [insert name of cop TV show here] ready to grill a perpetrator.

This forum was the first step in weeding out bad candidates like Fenton Patterson.
