Pride Parade 2012: Easier on transportation system over last year

Bodhi Spiritual Center says, “You are fabulous”. 

After last year’s near-meltown of transportation surrounding post-parade trips, parade organizers, aldermen, and the city redesigns the parade route, to make it longer and eliminate the hard to access “internal triangle” between Halsted and Broadway (with a vertex at Grace/Halsted/Broadway). The meltdown was that thousands of people tried to board at the CTA Belmont Station. The station stopped allowing new passengers 5 times to ease overcrowding. I can’t recall if trains had to skip the station because they were full.

The new design allowed for better access from more CTA train stations, more bus routes, and allowed for more even spectator dispersal along the route (with 6 pedestrian crossings operated by many police officers). The CTA, which is usually very good at communicating service changes, made a webpage dedicated to the Pride Parade and even designed their own map. That and their social media communication stressed the other stations paradeogers should use: Wilson, Sheridan, Addison, and Fullerton. That was in addition to the other bus routes that now had closer access to the changed route.

I wrote about the 2011 transportation experience on Grid Chicago in which I suggested shutting down private vehicle traffic on more streets and further away from the parade route, allowing only buses and bicyclists. I couldn’t tell if that happened this year. Last year I entered the parade “shed” on Belmont and then Addison. All east-west streets it seemed were closed to traffic from Clark Street to Halsted Street (which is a good thing). Clark Street was closed this year for a couple of blocks south of Diversey Avenue (also a good thing).

Chicago Fire Department miniature trucks. 

I didn’t notice these last year, but the fire department utilized ATV-like trucks to transport sick spectators. I didn’t see any Chicago police officers riding ATVs, but I may have read the department abandoned those because of their increased danger on crowds and the officer driving it.

I think the route changes were effective in making for a better (and safer) parade experience. Organizers and the City’s OEMC estimated attendance at 850,000, just 50,000 over last year. Because of the changes and the great weather (it was very breezy), I expected a higher increase. Some people who attended last year may have been turned off by the unease of the crowded viewing experience.

The Chicago Fire Department has one of the least useful Twitter feeds, but sometimes it’s hilarious

20 minutes ago, when the Twitter outage probably corrected itself, the Chicago Fire Department’s Office of News Affair tweeted three photos, without comment. I’ve posted them in reverse order.

The third photo (above) shows a BMW X5 SUV on top of a Jaguar sedan and Mercedes E320 sedan in a multi-level parking garage. The parking garage appears to be a split-level, and it seems the BMW SUV was moved forward from an upper level to the tops of these cars, which you can see in the second photo (below).

The photos appear to have been taken with a cellphone, using the flash. The license plates are obscured by their reflection of the flash. The car broke through the cables leading me to ask two questions: What is the level of tension on the cables? How fast did the car travel?

The @CFDMedia account is often cryptic. The Chicago Sun-Times provided more information an hour later:

A 74-year-old man driving a 2012 BMW X5 crashed through cable barriers separating two levels of a Loop parking garage Thursday — and his SUV came to a stop atop a 2005 Jaguar and a 2003 Mercedes-Benz parked on the level beneath him, police said.

Police cited the 74-year-old with driving too fast for conditions.

CDOT’s response to helmet inquiry at MBAC

Waiting at a red light on Milwaukee Avenue at Western Avenue. 

Erica Salem of the Chicago Department of Public Health (CDPH) emailed me in February asking about data on children’s bike accidents (crashes) and any related data about ER visits and head injuries. I forwarded her to my friend Bill who is working on such data at UIC’s Urban Transportation Center (UTC).

She was looking for information to make the case for kids to use helmets while biking. And she brought this up at the June 2012 Mayor’s Bicycle Advisory Council (MBAC). She’s a member of the council under the new rules and format.

Here’s a paraphrased version of the discussion:

Erica Salem (ES): How do you quantify the increase in bike riders in the city?

Mike Amsden: That’s a huge challenge. Bike/ped data collection is very difficult. Right now it’s just work trips, and there’s even talk of eliminating that. We do before/after data collection of bikeway facilities. That’s where this Green Lane Project will come in and help with promotion and resources.

ES: The CDC released data showing 88% CPS middle schoolers and 94% of CPS high schoolers don’t wear a helmet when biking. Some of us think there should be an ordinance for helmet use in children. And some of us don’t.

Charlie Short: Safe Kids Program out of Children’s Memorial has done bike helmet giveaway. Targets low-income children. That seems to be where most initiative is coming from.

ES: The funds are drying up. I’ve talked to them already.

James Boratyn (of Illinois Department of Transportation): IDOT helps fund Children’s Memorial’s Safe Kids Program [also funds Bike Ambassadors]

Alex Wilson (of West Town Bikes): Major issue was storage concerning their move. We just filed a grant for 500 helmets.

Luann Hamilton (representing the Chicago Department of Transportation): We’ve always taken the position to provide education, outreach, and providing free helmets, as opposed to mandate. Of all the issues the police are dealing with, it doesn’t seem like a useful way to deal with the issue. [emphasis mine]

A cogent and welcomed response.

Mayor Bloomberg (of New York City) responds directly to a question about helmet laws:

It would be better if everybody wore a helmet. I think in a practical sense a lot of people won’t, and they’re better off taking a bike than driving or walking in the streets and getting pedestrian accidents (sic). The most important thing we can do is separate bicycles lanes from traffic, and that’s one of the things we’re really trying to do.

Infrastructure and traffic enforcement will do more to reduce injuries than helmets.

My friend Brian pointed me to this article about how a helmet law may make a killed child’s parents (somewhat) responsible for their own child’s death. A 14-year old boy was cycling and killed by a then-48-year old driver. The boy was not wearing a helmet but state law requires that children 15 and younger wear helmets while cycling. The lawsuit was filed by the driver, from prison, in 2010. I don’t know what the outcome is.

Stats from the OECD: Comparing traffic injuries of the United States and Netherlands

For an article I’m writing for Architect’s Newspaper about the Chicago Forward CDOT Action Agenda, I wanted to know about traffic injuries and fatalities in the United States, but compared to the Netherlands and Denmark and other places with a Vision Zero campaign (to have 0 traffic deaths each year).

I already knew the OECD had a good statistics database and web application. With a few clicks, I can quickly get a table of traffic injuries (casualties) listing just the countries I want. I can easily select the years I want, too.

In one more click the web application will show a time animated bar chart. A feature I’d like to see added is dividing the figure (in this case traffic injuries) by the population. Check out the video to see what it looks like. The United States looks to be in terrible shape, but our country has several times more residents.

I had trouble downloading and opening the CSV file of the data table I created. The XLS file was damaged, also. The built-in Mac OS X Archive Utility app couldn’t open the .gz file, but I used The Unarchiver app successfully.

My calculations, based on data from OECD (national population and traffic fatalities), Illinois Department of Transportation (IDOT), and the American Community Survey:

Fatalities per 100,000 in 2009

  • United States: 11.02472
  • Denmark: 5.48969
  • Netherlands: 4.35561
  • Sweden: 3.84988
  • Chicago: 16.74891
  • United Kingdom: 3.83555

Chicago’s fatality rate per 100,000 citizens in 2009 was 16.75 (473 deaths on the roads). The fatality rate dropped in 2010: just 11.65 deaths per 100,000 residents (315 deaths on the roads; the population also decreased).

Updated September 28, 2012, to add the United Kingdom. 

Slicing the crash data into interesting visualizations

The Chicago Crash Browser as it looks now. This only exists on my laptop and no place else. I can’t put it online because it’s so inefficient it would kill the server. 

I presented my Chicago Crash Browser to attendees of an OpenGov Hack Night three weeks ago and gathered a lot of feedback and some interest from designers and programmers there.

We collaboratively came up with a new direction: instead of focusing on creating a huge web application that I proposed, we (anyone who wants to help) would start small with a website and a couple of crash data visualizations. The visualizations would serve two purposes:

  • attract attention to the project
  • start building a gallery of data-oriented graphics that describes the breadth and extent of the crash data
