A before shot of Chicago’s first bike boulevard, and facility semantics

It looks like nothing now. It’s just a street with mixed one-way and two-way segments. The bike boulevard’s best idea is making it two-way for bicycling. One-way streets are annoying, especially to people new to the neighborhood (like when visiting friends). The route is Berteau Avenue, the site of the first bike boulevard, from Lincoln Avenue on the west to Clark Street on the east (dead ending at Graceland Cemetery).

Berteau Avenue - future bike boulevard

The eastern “entrance” to the bike boulevard.

CDOT is calling it instead a “neighborhood greenway”. I don’t know what’s so “greenway” about it, even after John’s interview with Mike Amsden of CDOT for Grid Chicago. Portland and Seattle have very specific stormwater management features built into their neighborhood greenways, so the names make more sense there. Chicago has a stormwater mismanagement feature: Deep Tunnel (or TARP; see more articles I wrote), where we are trying to build ourselves out of flooding. But it’s not possible. During every major rain storm we have to open the sewers and dump untreated stormwater and sewage into Lake Michigan. Many beaches close the next day.

A real bioswale

A bioswale in Portland, at the corner of SE Clay Street and SE 12th Avenue, collects water runoff from the street and sidewalks. The plants in the bioswale absorb the water they can; other water is cleaned and absorbed into the soil where it slowly enters the earth. The earth is probably the only underground reservoir we need. 

I understand the idea behind removing “bike” from the facility’s name, as the project is about traffic calming and making it safer and smoother for all transportation modes to maneuver on this street. That’s fine, but I’m hoping for bioswales and other features to be included in this facility.

Berteau Avenue - future bike boulevard

Berteau Avenue probably needs some new asphalt before the bike boulevard (or “neighborhood greenway” is developed).

This photo reminds me to ask CDOT if a repaving is part of the project. I presume it will be because it’s very dumb to install new pavement markings on bad pavement (but it happened at least once last year, on Armitage Avenue east of Western Avenue).

Courtenay School, which is on Berteau Avenue

I agree with the notion that streets with schools receive a higher priority than streets without, but I don’t think they should be weighted higher than streets with high bicycling volume or crashes (I don’t know exactly if there’s such a detailed weighting system in the bikeway planning section of the Chicago Bicycle Program).

There’s at least one building with active businesses on the route. This one has the EveryBlock headquarters inside.

Regional rail trains pass here

Metra is rebuilding tens of viaducts on the Union Pacific North line, including this one over Berteau. Not all the streets have underpasses so Berteau was a natural choice as an east-west route in the neighborhood because of this barrier.

I took all of these photos with a Panasonic GH1, and accompanying lens, a LUMIX G 20/f1.7mm.

More discussion on this is in the comments below, on The Chainlink, on Grid Chicago, and on EveryBlock

The fixie-hipster index for this bike rack is near 1

Upon leaving the Third Thursdays party at the Chrome store at 1529 N Milwaukee in Wicker Park I spotted a bike with a funny attachment on the stem. After uploading the photo, I inspected it more closely and saw that four fixed gear bikes were locked to a single bike rack.

The fixie-hipster index for this bike rack (for this block, even) is nearing 1! Or 100%. Or 1:1.

But Chicago didn’t even place in the Top 25 Hipster Places in America.

What is Conversation Cycling?

Mikael Colville-Anderson posted a link to this photo set called Conversation Cycling (his photo above). The concept of Conversation Cycling is simple:

Build a bikeway so two people can cycle side-by-side to have a pleasant chat. 

I want this for Chicago. When you ride with friends, how would you prefer to ride: yelling ahead in our narrow bike lanes or conversing to the side? This is sometimes possible on the Lakefront Trail, but not always: the Lakefront Trail’s maximum width is the same as the standard with for cycle tracks in Europe!

Bike lanes in the United States, when they’re available and not being parked in, are not even wide enough for one person to ride without danger of being doored. It’s not surprising this is the case. In addition to how we prioritize the movement of automobiles and the placement of parking before pedaling, the national minimum width for a bike lane is 4 feet (without gutter), or 5 feet when next to parked cars or with a gutter.

I gathered some hard evidence: My handlebars are 28 inches wide. The door of my roommate’s car is 32 inches wide. 28+32 = 60 inches, or 5 feet. And that’s without a buffer. Essentially, bike lanes as we’ve built them are not compatible with the rest of the street.

Crashes by bike or by foot at different intersections

While working on a private web application that I call Chicago Crash Browser, I added some code to show the share of pedestrian and pedalcyclist crashes. The site offers users (sorry I don’t have a web server that can make it public) a list of the “Top 10” intersections in terms of bike crash frequency (that’s bike+auto crash). You can click on the intersection and a list will populate showing all the pedestrian and pedalcyclist crashes there, sorted by date. At the bottom of the list is a simple sentence that tells what percentage pedestrian and pedalcyclists made up at that intersection.

I’m still developing ideas on how this information may be useful, and what it’s saying about the intersection or the people using it.

Let me tell you about a few:

Milwaukee Avenue and Ogden Avenue

I mentioned in my article Initial intersection crash analysis for Milwaukee Avenue that this intersection is the most bike crash-frequent.

23 crashes within 150 feet of the center, 2005-2010

82.61% bike crashes **

17.39% ped crashes.

Ashland Avenue and Division Street

28 crashes within 150 feet of the center, 2005-2010

46.43% bike crashes

53.57% ped crashes **

Milwaukee, North and Damen Avenues

46 crashes within 150 feet of the center, 2005-2010

39.13% bike crashes

60.87% ped crashes **

Halsted Street, Lincoln and Fullerton Avenues

38 crashes within 150 feet of the center, 2005-2010

42.11% bike crashes

57.89% ped crashes **

Montrose Avenue and Marine Drive (Lake Shore Drive ramps)

11 crashes within 150 feet of the center, 2005-2010

90.91% bike crashes **

9.09% ped crashes

Why do you think some intersections have more of one kind of crash than the other?

The Chicago Crash Browser can be made public if I have a host that offers the PostgreSQL database. Do you have one to offer?

Carnage culture dispatch #1

I’ve been a “fan” of carnage culture news and discussion for several years, mainly since I started reading Streetsblog (probably in 2007) and their Weekly Carnage series. I write about “carnage culture” here and a little bit on Grid Chicago. But on Grid Chicago I tend to keep the coverage about crash data plus more “reasonable” (a euphemism for less angry, maybe) and objective.

Carnage culture to me is a description of the level of life and property damage Americans are willing to accept as a cost of doing business, and a cost of living. And I think that level of acceptability is much too high. Is the person responsible for these crashes paying for the damage they caused? Did the City bill the driver for the trees, curbs, landscaping, and guardrail he ran into?

I present here the first Chicago Crash Diary. From the photos and background information I received from a reader, combined with the Illinois Department of Transportation crash data, I was able to “reconstruct” a particular damaging crash in 2010. I made a color flyer from this information to quickly distill the details.

It seems continuing our system of having extremely high health care costs (without an equivalent return in quality or faster care when compared to countries with lower health care costs) is an acceptable cost of perpetuating backward ideas about society’s responsibility to take care of its members and refusing to allow a system that shares health care costs for those not already covered by Medicare, Medicaid, or child health insurance programs.

This is like carnage culture: we accept the damage to property, to human lives, and to society, to continue a culture (including our built environment) that depends on and glorifies automobile ownership and driving to places where other modes suffice. Our culture that allows unlicensed drivers, uninsured drivers, drivers with limited education (driver’s education is not needed for those 18 and older), being distracted by cellphones, and lax enforcement,* is the same one that allows $300 billion to be spent on “picking up the pieces” after crashes (study from AAA by Cambridge Systematics). But ours is the same culture that builds its cities and neighborhoods and places of employment to only be accessible by those who can drive.

The cost of crashes are based on the Federal Highway Administration’s comprehensive costs for traffic fatalities and injuries that assign a dollar value to a variety of components, including medical and emergency services, lost earnings and household production, property damage, and lost quality of life, among other things. [This story is interesting because the press release’s angle was that crash costs are three times higher than congestion costs, which is constantly in the news; congestion is apparently something we care more about.]

I don’t think $35 per month liability insurance, or the police, district attorneys, and courts, are protecting us from this damage.

*I could go on. Just search for “top causes of car crashes”.
