Rambling about automobile crash data and cellphone distraction

October 4, 2011 / / 0 Comments

How often do bicyclists get involved with crashes because of cellphone distraction? See the table below. And how many crashes are caused by the bicyclist being distracted by a cellphone? We won’t and don’t know. 

The Chicago City Council will vote tomorrow on ordinance 02011-7146 to add a new section in Chapter 9 of the Municipal Code of Chicago: “9-52-110 Use of communication devices while operating a bicycle.”

In a Chicago Sun-Times article today, Matthew Tobias, the Chicago Police Department’s deputy chief of Area 3 patrol, reported on the number of citations that the department has issued to drivers in violation of the cellphone ban: “from 2,577 administrative violations in 2008 to 10,920 in 2009 and 19,701 last year” (known as “citations issued” in the table below).

I looked at the crash data to see how many crashes were coded as having been caused by “Distraction – operating an electronic communication device (cell phone, texting, etc)”.

Out of 274,488 recorded crashes in 2008, 2009, and 2010, there were 331 crashes which had a Cause 1 or Cause 2 of “Distraction – operating an electronic communication device (cell phone, texting, etc)”. The table below compares the rates of crashes to the rates of citations issued and the number of crashes that the police noted were caused by cellphone distraction. It also shows the number of these “cellphone distraction” crashes that involved bicyclists and pedestrians.

Year Citations issued Automobile crashes Cellphone distraction crashes % of cellphone distraction crashes Involved with bicyclists? Involved with pedestrians? National VMT (billions)*
2008 2577 111,701 91 0.081 3 10 2973.47
2009 10920 81,982 130 0.159 1 7 2979.39
2010 19701 80,805 110 0.136 6 8 2999.97

Maybe this data shows that the increased enforcement is causing fewer crashes?
However data for cyclists’ involvement in crashes and their cellphone use WON’T BE recorded unless there’s a rule change as the cause is only recorded for the vehicle involved in the crash, and bicycles are devices, not vehicles.

None involved fatalities.

*Yep, that’s 2 thousand billion. Read it like this, 2 trillion 973 billion and 470 million. VMT data from Bureau of Transportation Statistics.

Video tour of Open Streets

What is Open Streets?
It’s when a street is closed to cars and transformed into a safe place for fun and recreation. Read more on Grid Chicago.

Cycling in Milwaukee

September 27, 2011 / / 0 Comments

I visited Milwaukee on the Sunday before Labor Day this year. I haven’t uploaded any photos or written about the trip. My friend Brandon and I brought our fixed-gear bicycles and rode around town for several hours. Here’s a video of some of their streets and trails.

What is a utility bike

September 26, 2011 / / 0 Comments

Well, if I had to choose, it’s the WorkCycles Fr8.

But if I had to define it, here goes:

  1. It can carry stuff so that I don’t have to carry it on my person, thus hurting my body. Carries in such a way so as to not negatively affect the handling and maneuverability of the bike.
  2. Has a design with devices, features, elements, materials that help prolong the life of the bicycle. This includes chain guard to prevent rust, fenders to prevent dirt, internal gearing to make that last longer, etc…
  3. Can be ridden by a variety of person sizes (I’m not sure if this represents utility, not 100% sure on this one).

Why does this matter?

Oregon Manifest judges chose the winning bike on Friday, September 24, 2011, and it’s far from being the ultimate utility bike.

Tony’s bike – centered around an electric pedaling assist — was specifically designed to get people out of cars, introducing amenities that drivers have grown accustomed to on the road;  stereo, locking storage, stable loading and a huge dose of Fun Factor.

And I wasn’t the only concerned observer. Travis Wittwer, a Portland resident, was present at the announcement and wrote on Bike Noun Verb, in a post titled The Cargo Bike Future Sucks:

There was a palatable pause as the first place winner for the Ultimate Utilitarian Bike was announced at the the 2011 Oregon Manifest awards. The pause was long enough to register as a pause. A stop. It was uncomfortable. Clearly people everywhere in the crowd were saying, “What the hell?” I looked around and saw other people looking around. There was some confusion.

It doesn’t meet my definition of utility bike above:

  1. The wide front rack is mounted to the steering and thus will make maneuverability difficult. The double-leg kickstand is not very wide.
  2. The drivetrain is exposed, it uses electrical parts that will fail or need maintenance that many people will not be able to provide.
  3. The high top tube may make it difficult for some to mount the bicycle.
I do love the locking storage, though!

Notable about Chicago transit: Bikes

I forgot where I heard this, but it’s from a guy named Adam (he might be from Ireland*):

Biking in Chicago is great… because you can give up and at any time… and put your bike on a bus.

He’s right – every single one of the Chicago Transit Authority’s 2,000+ buses have bike racks to hold two bicycles.
