Put the first cycle track somewhere else

Updated 06-03-11: Grew the list below from 11 locations to 15 to match the full list on wiki.stevevance.net.

I propose 15 locations for Chicago (see link for ideal segments):

  • Archer Avenue (whole length)
  • Blue Island Avenue (between UIC and Pilsen, but then connecting Pilsen to Little Village via 26th Street)
  • Chicago Avenue
  • Clybourn Avenue (entire stretch, from Belmont to Division)
  • Damen Avenue (really easy south of Congress; difficult between Chicago and Congress, and north of Chicago)
  • Fullerton Avenue
  • Grand Avenue (at least California or Kedzie to Navy Pier)
  • Halsted Street (in some discrete locations)
  • King Drive (connecting downtown/South Loop to Bronzeville, Hyde Park, Washington Park)
  • Kinzie Street (connecting one major bike laned street, Milwaukee, to another, Wells)
  • Ogden Avenue (the entire street, from the city boundary on the southwest side to its dead end at the Chicago River near Chicago Avenue)
  • Vincennes Avenue (I haven’t figured out the extents for this one)
  • Wabash Street (connecting downtown and IIT)
  • Washington Boulevard/Street
  • Wells Street – this may be one of the easiest locations to pull off, politically at least, especially if Alderman Reilly pays for all or part of it with his annual appropriation of $1.32 million (“menu funds”).
  • Western Avenue

Notice how I didn’t propose Stony Island between 69th and 77th.

I selected streets where there’s already much cycling happening – whether it’s directly on that street and for long distances or neighborhoods the street passes through. I also selected streets where there’s some cycling happening but make the all-important bikeway network connections on streets with high automobile or high speed traffic (like Western Avenue) or lead to places that attract trips by bike (like train stations). And I selected streets that lead towards downtown, to transit stations, to schools, and to jobs. The segment of Stony Island from 69th to 77th leads to a small shopping district on 71st Street and a Metra Electric train station with 197 weekday boardings (from 2006 survey).

A cycle track location will be most effective where it can:

  • attract the most new riders (goal #1 in the Bike 2015 Plan)
  • make the biggest increases in safety by reducing injuries (goal #2 in the Bike 2015 Plan)
  • (and for the city’s first cycle track, be used by the most existing riders)

It is in these locations where these facilities will be quickly adopted by people bicycling to and from that neighborhood for their shopping, school, and social and work trips. It will also help lead the City and its residents to attaining the quite ambitious goals of the Bike 2015 Plan (have 5% of all trips under 5 miles by bike and cut frequency of injuries by half).

NACTO’s new Urban Bikeway Design Guide recommends cycle tracks for “streets on which bike lanes would cause many bicyclists to feel stress because of factors such as multiple lanes, high traffic volumes, high speed traffic, high demand for double parking, and high parking turnover.”

Stony Island between 69th and 77th has many lanes, high speed and high volume traffic, but low parking turnover (there’s a low density of businesses and many have their own parking lots). This area has low cycling levels and a grand bike facility here would do little to help Chicago reach the plan’s goals. We won’t see any benefit in terms of mode shift here.

Without further information on the intentions (see paragraph “On intentions” below) of those who selected this location and their goals for Chicago’s first cycle track, my surmise is that it was selected because of the roadway width (four lanes in each direction with a wide parallel parking lane, see map), where taking away a lane from car driving may be more politically and technically feasible – I believe this is the wrong way to begin a protected bike lane program.

On intentions: A former CDOT employee left a comment on my blog in December 2010 addressing the site selection: “Stony Island was recommended as a part of a Streetscape Master Plan [I can find no information about this plan]. It wasn’t like people were sitting around saying ‘Where can we put a buffered bike lane?’ It was really just a plan of opportunity since Stony Island is crazy-wide. Nevertheless, it will connect with a new bike path along the side of Marquette Dr in Jackson Park, which connects to the Lakefront Trail.”

While Stony Island could be a good demo location to prove that this type of facility won’t be harmful to drivers, as a demonstration of the power of protected bicycling infrastructure, it won’t do a good job.

Commuting rates in Chicago – a conversation

I had this conversation last night with a friend from Chicago. Enjoy. Data is from the American Community Survey, Table S0801. If you were to rate how much we bike, from a “typical Chicagoan’s” point of view, he would be “eccentric” and I would be “psychotic.”

Me
A friend of mine in Europe asked for bicycle commuting statistics for Chicago.
Man, the numbers were sad.

Friend
No shit.

Me
if we look at the 3-year estimates for work trips, then it’s
-2005-2007: 0.9%
-2006-2008: 1.0
-2007-2009: 1.1

Friend
Chicago is also a gigantic, sprawling modern city of hundreds of square miles and wide roads designed for masses of cars.

Me
And if we look at the 1-year estimates, which Matt argued on my blog are useless, it’s
-2005: 0.7%
-2006: 0.9
-2007: 1.1
-2008: 1.0
-2009: 1.1
The 3-year estimate has a MOE of ±0.1 so essentially, it could mean no change from year to year.
And the 1-year estimate has a MOE of ±0.2, so again, it could mean no change from year to year
UGH

Friend
Comparatively, old European cities don’t have a lot of bandwidth for autos and have density where people take short trips.
That’s still probably two or three times the distance people in Copenhagen or Cambridge or Amsterdam.

Me
So let’s say 50% of trips are 5 miles or less, and 25% of trips are 2.5 miles or less.
Yet 1% of all trips are taken by bike
If we could just DOUBLE that, it would be a miracle
The Bike 2015 Plan’s goal is to have 5% of all trips under 5 miles by bike.

Friend
That’s an ambitious goal.

Me
We don’t have any baseline data to show how many trips under 5 miles in 2006, at the inception of the Bike 2015 Plan, are by bike. In the end, we’ll never know if our ambitious goal was attained!

Be specific. Be, be specific.

Update September 5, 2011: I gave a short speech to Moving Design participants about language and word choice, a kind of follow up to this article, as a “policy insight of the day.”

When speaking or presenting, be as specific as possible. The following are examples specific to the course of transportation discussions.

“Car traffic banned from this road.” Are you also banning trucks and SUVs?

“Vehicles will be rerouted.” Does this include those riding bicycles? Here’s an example of a current detour that only mentions cars, buses, and trucks. Which route should someone riding a bicycle take? Sometimes state and local laws will classify a bicycle as a vehicle, but then exclude it in specific passages – it’s weird. Better just call out specific vehicles, be they of the motorized or human-powered variety.

“Cars are aggressive to bikes.” Cars and bikes don’t operate themselves.

“We plan to narrow the road to calm traffic.” Are you going to narrow the road, or narrow certain lanes and reassign portions of the road to different uses, like a protected bike lane, or wider sidewalk? Then give the measurement of lanes, the sidewalk, and the curb face-to-curb face width. Consider that “street” is not a synonym for “road.” Road often represents what’s between the curbs, and the pavement, while street includes the road as well as the sidewalk. Street is a bit more abstract as well, sometimes meaning the activity that occurs on or around roads (like “street life”).

“Ignorant drivers…” Or do they lack specific education and relevant information?

This bikeway in Bremen, Germany, uses both color and pavement design to delineate space for people bicycling (like me) and people walking.

TransportationCamp: Real-Time Pedestrian and Bike Location, Session Two

Real-Time Pedestrian and Bike Location How can we get it? What can we do with it? How can it not be creepy?
By Eric Fischer.

My summary of the discussion

There are many existing data sources that are published or have APIs that could stand as reasonable proxies for tracking people who are walking, biking, or just ambling around the city – some of this information is given away (via Foursquare) by those who are traveling, and other information is collected in real time (buses and taxis) and after the trip (travel surveys and Flickr photos). I don’t think the group agreed on any good use for this data (knowing where people are in the city right now), nor did the group come up with ways to ensure this collection is not “creepy.”

Eric’s original question involved the location of people bicycling, but the discussion spent more time talking about pedestrians. However, some techniques in tracking and data gathering could be applied to both modes.

See final paragraph for links on “further reading” that I find relevant to this discussion.

Schedule board at TransportationCamp West on Saturday in San Francisco at Public Works SF, 161 Erie Street.

[Ideas and statements are credited where I could keep track of who said what, and if I could see your name badge.]

Eric, starting us off:
We have a lot of information about where motor vehicles (MV) are in cities.
A lot of experience of city is not about being in a MV, though.

How many bikers going through intersection that are NOT getting hurt.
Finding places where people walk and where people’ don’t.

Where do people go on foot and on bikes?
As far as I know this isn’t available

Foursquare has benefits (awards) so people are willing to give the data, but we don’t want another Please Rob Me.

In SF, there are flash mobs, sudden protests, Critical Mass

Data sources:
-buses – boarding and deboarding – you can get a flow map from this. Someone said that Seattle has this data open.
-CTPP (Census Transportation Planning Package)
-city ped count
-Eric: Where people get on/off taxis.

“CycleTracks” – sampling bias, people with iPhones
-70% of handheld devices are feature phones, not smart phones. So there’s another sampling bias.

Opt-in factor
How do you sample?

SF Planning Dept. had a little program or project ask people to plot on a map your three most common walking routes.
What is your favorite street, and where do you not like to walk?

Eric: My collection tool is Flickr. Geotags and timestamps.
flickr.com/walkingsf

Magdalena Palugh: Are there incentives for commuting by bike? There are incentives for people who vanpool.
If there is incentive, I would gladly give up my data.
Michael Schwartz (SFCTA, sp?) What is difference <> SFCTA/MTA?

-If part of this is to get at where the trouble spots are, could you have people contribute where the good/bad parts are? “This overpass really sucks.”

Tom: Can you get peds from aerial images?
-Yes, but there’re too many limitations, like shade, and tree cover. Also, aerial images may be taken at wrong time (for a while the image of Market/Castro was during festival).

Brandon Martin-Anderson: What strategies have you tried so far?
-aerial images
-Flickr/Picasa location
-Street View face blur (a lot false positives)
Anything you plot looks kind of the same.

People like to walk where other people are. For safety reasons. -Good point on real-time basis.
Eric: Not a lobbying group for peds.
Eric: Find interesting places to go.
Richard: We need exposure data.

Paris bike sharing report showed that “Cycling is faster on Wednesdays.”
Europeans more open to sharing their private details – possibly because of stricter regulation on what agencies can do with the collected data. (There was a little disagreement on this, I personally heard the opposite).

Andrew: Can we use something like Xbox Kinect to track these people?

National Bike/Ped Documentation Project – same format
Seattle – 4 different groups that do annual bike counts. UW bike planning studio.

Who pays for this?
-Transportation planners pay for this.
-Private development projects (from contractor).
-Universities, NSF, Google
-Community groups –

Why I’m keeping track of Brooklyn’s bike lane drama

A protected bike lane on Prospect Park West in Brooklyn installed by the New York City Department of Transportation in summer 2010 is under attack. Two groups have sued the city in March 2011 over the lane’s installation. The city published a report that indicated that the new bike lane contributed to fewer drivers speeding, a decrease in injuries, and an increase in compliance of the law banning bicycling on the sidewalk.

I have written several articles about the drama, including New Yorkers really want to keep their bike lanes.

Why am I paying attention?

I believe this fight may come to Chicago when the Chicago Department of Transportation starts planning the cycle track to be installed on Stony Island Avenue between 69th and 77th Streets, which may be installed as soon as 2014.

And when the fight does come, I want to know as much as possible about how to defend Chicago’s first cycle track.

Will we be successful and install a similar facility in Chicago? Photo features New York City’s first cycle track, from 2007, on 9th Avenue.
