I need a visualization tip for showing pedestrian and auto traffic in downtown Chicago

January 30, 2013 / / 34 Comments

Madison Street over the Chicago River. Pedestrian traffic is very high, and very constrained, near the Metra stations.

Here’s the goal:

Show that pedestrians don’t get sufficient space or time to have a high quality pedestrian experience given that they comprise the largest mode share on streets in the Loop. The trips are highly delayed at traffic signals, pedestrian space is encroached upon because of automobile turning movements, and the sidewalks aren’t wide enough for two-way or even one-way traffic at certain times of the day. It’s possible to build our way out of pedestrian traffic…

Here’s an example data set:

On October 3, 2006, for all of the 24 hours, at 410 W Madison Street, there were 17,100 automobiles counted.

On some day in summer 2007, for 10 hours, at 350 W Madison Street, there were 43,987 pedestrians counted.

The two locations are practically the same as the bridge here prevents more pedestrians or automobiles from “slipping in”.

It’s possible to download the data sets from CDOT’s Traffic Tracker so you can see the whole city on your own map, but you’ll have to do some digging in the source code to find them.

Destination streets are rarely the best places to bike

January 29, 2013 / / 22 Comments

This family took to riding on the sidewalk of Division Street instead of in the bike lane. They’re riding the stylish workhorse WorkCycles Fr8. Once I saw them riding the blue one, I had to get a different color. 

My friend Calvin Brown, a circumstantial urban planner, is always giving me Jane Jacobs-style observations about how citizens use their cities.

“Destination streets are the ones I avoid biking on because there’s so much car traffic there. Traffic must be balanced between streets that are good for biking and ones that aren’t currently good.”

In other words, because it’s a destination street (a place where there are a lot of retail outlets, venues, points of interest) it induces a lot of car traffic. Lots of car traffic discourages people from riding bikes, and makes it difficult for those who already are.

To me, a great example of this is Division Street. There’s a bike lane there from Ashland to California Avenues, and has tons (tons!) of restaurants and some night clubs. Yet that causes a lot of taxi traffic, people driving their own cars, looking for parking, jutting into the bike lane to see why traffic is going slow or backed up (um, because there are ton of cars!), and valet and delivery drivers blocking the bike lane.

It’s exactly this traffic, though, that keeps these places vibrant, desirable, and healthy (from an economic standpoint). The solution for bicycling is easy: swap the car parking with the bike lane so that bicycling isn’t affected by a majority of the aforementioned traffic maneuvers.

Calvin’s “destination streets” examples were Grand Avenue and Chicago Avenue. Neither has bike lanes, and both have 2 travel lanes in each direction. Grand has destinations from Racine Avenue to Ashland Avenue and Chicago has destinations from Ada Street to Western Avenue. I’d wager that if you narrowed those roadways by installing a protected bike lane you’d get slower traffic and higher business receipts.

Chicago Avenue at Hoyne Avenue is a particularly stupid part of Chicago Avenue: The Chicago Department of Transportation installed a pedestrian refuge island here. After several years and at least 4 replaced signs due to collisions of automobiles with it, the design hasn’t been modified. The island in and of itself did not change the speed of those who drive here, as the roadway’s width remained static.

I wish I wrote a blog about food trucks sometimes: Chicago has made it really difficult for expansion

Most of my time (because it’s actually my job) is to blog about transportation. This blog is about cities, and cities are about food trucks, so I guess it’s fine. I neither own a food truck, nor patronize them, but I’m fascinated by the process of how city administrations are handling them, whether through some kind of indifference or making regulations that seem only to make running a food truck more difficult than it should be.

At a “mobile food summit” at the University of Chicago in the spring of 2012, I learned from the sponsor Institute for Justice that they were suing cities for passing unconstitutional laws that regulated business not for health and public safety, their duty, but to protect the economic well-being of other businesses. Based on that knowledge, Chicago did this with the food truck ordinance from July 2012.

The Chicago Tribune reports today, in summary form, the current status of this regulation (here’s the full article):

No city licenses for food trucks

The city hasn’t licensed a single food truck for onboard cooking since the practice was approved in July. Some food truck operators say they’re scared off by the extensive red tape they foresee in the application process. Of the 109 entrepreneurs who have applied for Mobile Food Preparer licenses, none has met the city’s requirements.

I looked this up to know more and I found short commentary on Reason magazine’s blog:

The City of the Big Shoulders is hungry. And 109 entreprising folks want to help feed it. Too bad they’re not allowed to.

For example, the Tribune interviewed proprietors, one of whom said, “While most of its provisions are similar to those in other major cities, [Gabriel] Wiesen said, Chicago’s code includes rules on ventilation and gas line equipment that “are meetable but extremely cumbersome and can raise the price of outfitting a truck by $10,000 to $20,000.”

The bit about the regulation possibly being unconstitutional is that the food trucks with this license (which allows them to cook on the truck) must have a GPS device recording their position during retail hours and cannot operate within 200 feet of a brick-and-mortar restaurant (except in designated mobile food truck loading zones, for a maximum of two hours). Restricting where and when a food preparation business can operate is the tricky part: the city doesn’t regulate this for brick-and-mortar restaurants (except for zoning, which is much more lax and is intended to keep incompatible land uses away from each other).

What abysmal pavement quality on a brand new bike lane means

January 4, 2013 / / 16 Comments

Approaching the intersection and bike lane minefield. 

I find it very embarrassing that Chicagoans are supposed to ride their bicycles in this. I feel embarrassed riding my bike in this. I rode my bike on this pavement of abysmal quality and then felt ashamed and uncomfortable that I exited the bike lane and rode elsewhere.

The bike symbol succumbs to flooding which occupies half the bike lane’s width. 

I felt like a person in a wheelchair given an “accessible” theater seat behind a column that blocks a majority of my view of the stage. I felt like I was a reporter at a newspaper given a new computer where the keyboard was missing 42 keys. The bike lane was unusable, I was the butt of a cruel joke. This felt like a pittance, throwing crumbs to the masses.

2013 April Fool’s Day came early, in fall 2012. 

The photos in this post show a bike lane in Douglas Park against the curb, with a painted buffer, running in a minefield of patches and potholes on asphalt pavement. The bike lane was installed in the fall of 2012, as part of Mayor Emanuel’s efforts to construct 100 miles of protected bike lanes. The goal has since been reduced after the definition of a protected bike lane was surreptitiously changed. The change was revealed by Grid Chicago.

You can find this at the intersection of Sacramento Boulevard and Douglas Boulevard in Lawndale on the Near Southwest Side of Chicago. View more photos of this and the other West Side Boulevards bike lanes on my Flickr. They’ve probably been the most controversial: there were complaints because of ticketing cars parked in the under construction bike lane on Marshall Boulevard; then there were complaints about the “decreased safety” of the protected bike lane on Independence Boulevard which has prompted CDOT to agree to remove it and replace it with a buffered bike lane. The Independence Boulevard debacle started because of ticketing cars parked in the under construction bike lane – I doubt it would have become an issue if cars weren’t ticketed.

Franklin Boulevard at Kedzie Avenue, taken on the same day. Thankfully it’s wide enough that you can bike around it while still being in the bike lane. 

Free high resolution maps of Chicago on which to draw

November 28, 2012 / / 0 Comments

For a Grid Chicago article I was writing, I wanted to draw on a map to demonstrate to readers where people were commuting and not commuting. I wanted the map to show CTA lines. I didn’t want to use a Google Maps screenshot because it would have been low resolution, and I didn’t think the styling would be appropriate.

I opened up TileMill and whipped up my own maps! I already had the base layers set up for the Chicago Bike Map app, so I duplicated that project and then added the Chicago Transit Authority and Metra train lines with data and styles prepared by OpenPlans (created for its Chicago bike sharing Shareabouts installation; download the data and styles here). Highways, the most common geographic reference point in cities, are also included on the map.

Data comes from OpenStreetMap contributors and the styling is OSM-Bright.

Go grab them on Flickr. Use them as needed but please provide attribution to “Steven Vance, OpenPlans, and OpenStreetMap contributors”.
