Stop locking your bike at the Clybourn Metra station overnight

Existing bike parking at the Clybourn Metra station

This is a resolution.

WHEREAS, I love GIS.

WHEREAS, I was reading this blog post on the Azavea company blog about bike theft prediction and trends in Philadelphia.

WHEREAS, I analyzed bike theft location in Chicago in 2012 and the Clybourn Metra station emerged as the most frequent Metra theft location.

WHEREAS, I searched the Chicago Stolen Bike Registry for “clybourn” and several thefts have been reported to the registry in 2013.

WHEREAS, I believe the Chicago Police Department still doesn’t allow searching of their database for bike thefts thus leaving the CSBR as the premier source of data.

WHEREAS, I am watching this show called The Bletchley Circle wherein a group of four fictional women who cracked codes in World War II are solving a murder mystery in 1950s London.

BE IT RESOLVED that you should not leave your bicycle parked at the Clybourn Metra station overnight as it is a terrible place to leave a bicycle parked. Why? No one is around most of the time to socially secure your bicycle.

This is a great place to get your bike stolen. In the dark. Overnight. With no one around to see it happen. 

How many cars are in Rogers Park?

November 10, 2013 / / 4 Comments

There are a gazillion cars in Rogers Park, and there’s no place to park them. That’s the declaration you would gather if you listen to “Lakefront Car Tower” (a parking garage) proponents, including the 49th ward alderman, Joe Moore.

The parking problem is so bad in Rogers Park that a parking garage at Sherwin Avenue and Sheridan Road that would provide less than 100 overnight parking spaces to the public was actually sent from Asphaltia, the god of car parks. It’s so bad that “[m]any car owners find themselves stuck in their home at night” – yes, the alderman really published that on his website – because they find a parking space on Friday night and can’t move the car until Monday morning. The horror of using your feet, pedals, the bus, the train, car sharing, paratransit, or a Segway!

(I’d love to get into parking pricing policy now, but I’ll just leave you with this: of course there is going to be a demand problem when the supply of publicly-owned on-street parking costs $0 per year.)

This post is actually a tutorial on how to use United States Census data to find how many cars are in the neighborhood of Rogers Park, not a laugh about Asphaltia’s teachings.

Let’s begin! Continue reading

On Active Transportation Alliance’s transportation summit

November 3, 2013 / / 0 Comments

Active Transportation Alliance invited Eric Hanns and I to speak about “using data for advocacy” at their first annual transportation summit held after a member meeting two Saturdays ago. My and Eric’s talks were complementary and centered around the data tool I built and which Eric and the other volunteers in the 46th Ward participatory budgeting program used to prioritize and market infrastructure projects in Uptown.

The tool in question is the Chicago Crash Browser I made last year and improved this year to load data faster, with great help from the Smart Chicago Collaborative and several members of the OpenGov Hack Night group I cherish.

Click or tap a spot in Chicago to retrieve the number of bicyclist-car and pedestrian-car crashes within 150 feet. With this information, the PB volunteers could show the alderman how important it was for him to support bike and pedestrian infrastructure projects in the ward, and to persuade ward voters to fund these projects.

Find more information about the four other summit “breakout groups” on Active Trans’s website. Eric and I prepared a “Using Data for Advocacy: Making the Case with Compelling Facts” handout which you can download as a PDF or see on our Google Doc. I’ve conveniently listed the links from the handout below but if you want more pointed advice on where to look for specific data, or get an answer to questions you have but don’t grok the context of each of these tools, leave me a comment.

Chicago’s train stations are dead zones

November 3, 2013 / / 10 Comments

Perhaps not all of them: Millennium Station, serving Metra Electric and South Shore Line trains, was rebuilt and given a facelift and new tenants (including a few restaurants) when the City of Chicago constructed Millennium Park atop it. And not Northwestern Station since it has two food courts, activity from the thousands of workers above, and the new(ish) French Market.

But look at Union Station and LaSalle Station – they tell passengers to stay away. It’s obnoxious (and noxious) to be in them. These two stations have quite the space available for pleasant activities and waiting areas. Union Station has the Great Hall and a bar but it’s also a Great Distance away from the platforms. LaSalle Station is probably the worst: a dozen machines squawk at waiting passengers – if there are any – to tell people who are blind where each track is. Every 3 seconds.

I made a video to demonstrate a little of how unlovable train stations are in the United States. Not every station has the squawk boxes right in the main, but empty, waiting area, but the desolation and difficult access is widespread.

There’s a whole lot of nothing at LaSalle Station. Photo by Jeff Zoline. 

Google Maps’s lies are why I made my own bike map

Bright green lines indicate trails while darker green lines indicate bike lanes.

Because Google Maps lies about where bike facilities are. Check out the bicycling layer at 16th Street and Wood Street in Pilsen, Chicago, Illinois.

The bright green lines represent trails, but the ones in this part of Pilsen are not trails. All of the north-south “trails” you see are actually sidewalks underneath railroad viaducts. The east-west trails…well, I’m not sure what they are but they are on elevated railroad property. Don’t go up there.

I created my own bike map to deal with the inaccuracies across Google Maps. I used my local knowledge (“ground truth”) and high-quality bike facility data from the Chicago Department of Transportation.

I also used contributions to OpenStreetMap, mainly for trails. I’ve been correcting and adding new bike lane data to OSM as CDOT installs them. View this area with OpenCycleMap’s tiles, which shows only bike lanes on 18th Street.

If you’re an editor on Google’s Map Maker data editing platform, please correct these errors. I would do it except that Google doesn’t allow others to benefit from my data contributions like OpenStreetMap does, where anyone can give and take. (I also had a negative experience on Map Maker, getting myself into a tiff with an unnamed user who disagreed with my changes, based on a personal visit to the location, that were not visible on the satellite imagery because that location had outdated imagery.)
