Bike lane mileage is the wrong metric for your city to publicize

May 28, 2014 / / 8 Comments

Sometimes I tweet things that get pretty popular and then I need to go into more details. Case in point:

Which I followed by tweeting:

Knowing how many miles of bike lanes you have has little importance in determining if I’m going to bike in your city when I visit, or if I’m considering moving there, or if I want to add you to a “bicycle friendly cities” list.

What’s more important is how much the number of people bicycling on those bike lanes has changed. This number will reflect the quality of your bike lanes. Are they still in good shape or have they faded a lot? Do they connect to each other to create a network, or are there gaps that increase the stress of a route? How have you treated the bike lane at intersections, the place where a conflict and crash is most likely to occur?

Chicago Tribune architecture critic Blair Kamin touched on these points in his recent critique, one of the few worthwhile articles the Tribune has published in the last year about bicycling, by interviewing an organization that tries to make it politically palatable to build unconventional – in the United States – bike lanes.

“Chicago has made incredible progress over the last few years,” said Martha Roskowski, vice president at People for Bikes, a Boulder, Colo.-based advocacy group. But, she added, “Chicago also has a ways to go.”

That’s saying it nicely.

Addressing the gaps in the city’s network of protected bike routes, Roskowski said: “People evaluate a potential bike ride on the basis of the weakest link, the scariest part of the trip, which might be a really busy road you have to ride along or across. People have tolerance for a little bit of that. But if it’s sustained or if it feels dangerous, they just won’t do it.”

Enter Close Calls, deteriorating bike lanes, bumpy pavement, and constant obstacles and you get Chicago’s ridiculously low bicycle commute to work numbers.

Since Emanuel took office in 2011, Chicago has installed 52 miles of protected bike lanes [it’s only installed 16 miles of protected bike lanes], which use a variety of means — plastic pylons, striped pavement markings and non-curbside parking spaces — to separate bikes from vehicles. That brings the city’s total bicycle lanes to 207 miles.

That’s cool that we have 207 miles. How many miles of streets without bike lanes do we have? It’s 4,000 and some change minus 207.

Why doesn’t Mayor Rahm Emanuel talk about how many people have taken up bicycling since he took office, or how many more trips Chicagoans made (and where) because of those 52 miles of new buffered and protected bike lanes?

He can’t say how many people are riding their personal bikes because the city doesn’t track this.

Conversely we can track Divvy bike-share use down to the minute and the company announced that Saturday, May 24, they had their most trips ever. Only to be eclipsed by almost 4,000 more trips on Sunday, May 25 (helped in no small part by the Bike The Drive event where people can bicycle on a Lake Shore Drive that’s closed to vehicles).

In another blow to good data for Chicago, Divvy will only be releasing trip data twice a year, while Citibike in New York City will be publishing it monthly, an improvement of Capital Bikeshare’s quarterly data releases.

If you’re not tracking who’s using your infrastructure, will you be able to know if the people you set out to attract have come out?

Respect the corner!

Buildings on corners should have corner entrances or minimally deviate.

Contractors work on building the new entrance.*

The residential building on the northwest corner of Milwaukee Avenue and Halsted Street was built in 2003 with a first-floor commercial space with an entrance on the Milwaukee Avenue side. Normally this wouldn’t be such a big deal – Milwaukee is a busy street and this side of the street has a fair amount of foot traffic. But the other side of the building, on Halsted Street, faces one of two entrances to the Grand Blue Line subway station and a major transfer bus stop.

7-11 is moving into the building and have built a new entrance out of the corner space with floor-to-ceiling windows. Now it’ll be much easier for transit riders to get to a convenience store. The other advantage is the added visibility: seeing the entrance from far away, from all sides, saves milliseconds in our internal GPS processing time – make a bee-line to the entrance instead of “hunting” it down after you make your way in the general direction of the building.

* You can see that there’s a step here so it’s not currently accessible. Originally this wasn’t the entrance so that makes sense. I don’t know what these contractors are doing but 7-11 must make the entrance accessible.

Let’s get rid of beg buttons

March 9, 2014 / / 28 Comments

As much as you may believe, because you encounter them so rarely, Chicago indeed has several types of “beg buttons”. This is a mechanism wherein a person walking along a street must apply to cross another street. You are begging for permission. They are not popular, many are not even hooked up anymore, and they don’t call the pedestrian signal any sooner (their purpose is to make the green traffic signal long enough for a person to cross).

Jan Gehl et. al. succinctly demonstrate in Cities for People the opposing methods of telling a person when they can cross the street (meaning cross traffic has been halted).

The 2013 Chicago Complete Streets Design Guidelines and 2012 Pedestrian Plan reorients the city to prefer facilitating and encouraging transportation by foot over all other modes of travel.

The Pedestrian Plan says that beg buttons should have an LED light that indicates to the pusher that the button has been pushed. (The Pedestrian Plan also calls “traffic signals” a high cost pedestrian safety tool, alongside the high cost of “pedestrian hybrid beacons” and the medium cost of “rectangular rapid flash beacons”. Slow traffic, on the other hand, doesn’t have an operating cost, but it definitely has a “we’re getting there cost”.)

The Plan also says to get rid of them “except for locations where they are necessary to bring up a WALK phases for pedestrians” and without saying what makes it necessary to bring up a WALK phase (versus always having a WALK phase for that direction of traffic) and if that “necessary” is aligned with the Complete Streets Design Guidelines’ paradigm shift. Systematically removing inoperable ones is a separate, medium term milestone (alongside developing a location database).

The CSDG thankfully considers many other realities in Chicago that go against the new transportation paradigm that puts the pedestrian first. For example, it calls for the systematic removal of all slip lanes – none of which I’ve heard or seen removed in the year since CDOT created the guidelines.

I want the city to systematically remove all beg buttons. If the green signal is too short for a person to cross the street, then it’s probably too short for a bicyclist to cross in the green signal (yes, this exists in Chicago). It also means the street is too wide to foster it being a place over being a pipe for cars. And if it’s not a place, what is it and why are people walking there? What personal needs – like a job, food, and socializing – are not being fulfilled where they live that people have to cross this road to meet those needs?

Updated March 10 at 12:56 to clarify what the Pedestrian Plan says about beg buttons.

Divvy isn’t a real bike

January 2, 2014 / / 0 Comments

Riding on Divvy in the snow.

Divvy, for the first time in its short, seven-month existence, shut down today at 12 PM on account of the weather and keeping members and workers – who move bikes, shovel snow, and drive vans around town – safe.

Every news media in town reported on the shutdown. Chicagoist, ABC 7, NBC 5, FOX 32, Chicago Tribune, Sun-Times – you name it they had it.

But nothing has been published, except parts of this story from DNAinfo Chicago, that discusses how bicycling – whether on Divvy or your own bike – is very difficult in Chicago winters because of the poor coordination between the Streets & Sanitation and Transportation departments’ snow removal efforts, and the slow pace at which CDOT gets around to removing snow from the protected bike lanes. (I was quoted, alongside someone I recommended the author get in touch with, and we have differing views on the matter.)

In winter the protected bike lanes are the only bikeable kind of bike lane as conventional bike lanes become snow storage areas because plows can’t reach further right when there are parked cars (to avoid knocking off car mirrors).

This problem is not unique to Chicago and other cities have solved it. The cold isn’t why people in Chicago stop biking: it’s that snow and ice make it even more difficult in a region with little, separated (meaning safe and desirable) cycling infrastructure. There are climes with similar and worse winters where a large portion of people who bike in the summer keep biking in the winter. Places like Boulder, Minneapolis, Montréal, and Copenhagen.

A well-plowed, separated bike lane in a Copenhagen winter. Stranded? Put your bike on the back of a taxi (their buses don’t allow bikes).

I think it’s good that news media have recognized Divvy’s position as a transit system in the area, which they do by holding it to the same, weird standard they do Chicago Transit Authority and Metra, and posting about it frequently. When the CTA or Divvy has some marginal or perceived issue with its finances or service, an article gets written. But when it comes to bicycle infrastructure they give the city a pass where it doesn’t deserve one.

The media cares about Divvy, but it doesn’t care about bicycling. It might be the 11,000 Divvy members (more than Active Transportation Alliance or The Chainlink), however, that gets the city to kick up its bike lane snow removal efforts up a notch and I anxiously await that day.

Getting a little closer to understanding Chicago’s pothole-filling performance status

December 21, 2013 /

Tom Kompare updated his web application that tracks the progress of potholes based on information in the city’s data portal in response to my query about how many potholes the city fills within 72 hours, which is the Chicago Department of Transportation’s performance measure.

He wrote to me via the Open Government Chicago group:

Without completely rewriting http://potholes.311services.org, I added a count of the number of open (not yet addressed) pothole repair tickets (requests) that exceed 3 days old. As of today, the data from the City of Chicago’s Data Portal shows 1,334 or the 1,404 open tickets in the 311 system are older than three days.

Full disclosure: The web app actually looks for greater than 4 days old. The Data Portal’s pothole data are only updated once a day, so these data are always a day old. 4 – 1 = 3.

Keep in mind that this web app only shows how many are yet to be addressed, and does not count how many have been patched within CDOT’s 3-day goal during some arbitrary time period. That is a much more intense calculation that this pure client-side Javascript web application can handle due to bandwidth restrictions on mobile (3/4G). This web app already pushes the mobile envelope with the amount of data downloaded. I can fix that, but, again, not without a rewrite.

Still, 1,334 open repair requests (12/16/2013 Data Portal data) is quite different than the number of open repair requests reported by CDOT (560 in Alley, 193 on street) on 12/16/2013. I’m not sure what is the difference.

This reminds me of a third issue with the way CDOT is presenting pothole performance data online (the first being that it’s PDF, the second that it doesn’t work in Safari). The six PDF files are overwritten for every new day of data. If you want information from two days ago, well you better have downloaded the PDF from two days ago!
