Statistical anomalies show problems with Chicago’s red light cameras

There has been a lot of fallout from the Chicago Tribune‘s report on problems with Chicago’s red light cameras. And the smoking gun was the improbable spikes in tickets handed out on single days or in short stretches:

From April 29 to June 19, 2011, one of the two cameras at Wague’s West Pullman intersection tagged drivers for 1,717 red light violations. That was more violations in 52 days than the camera captured in the previous year and a half…

On the Near West Side, the corner of North Ashland Avenue and West Madison Street generated 949 tickets in a 17-day period beginning June 23, 2013. That is a rate of about 56 tickets per day. In the previous two years, that camera on Ashland averaged 1.3 tickets per day…

City officials insisted the city has not changed its enforcement practices. They also said they have no records indicating camera malfunctions or adjustments that would have affected the volume of tickets.

The lack of records is significant, because Redflex was required to document any time the operation of a camera was disrupted for more than a day, as well as work “that will affect incident volume” — in other words, adjustments or repairs that could increase or decrease the number of violations.

In other words, graphs showing the number of tickets over time show big spikes. Here is one such graph from the intersection of Halsted and 119th Street:

As the article notes, there are a number of these big outliers in the data, outliers that would be difficult to miss if anyone was examining the data like they were supposed to. Given the regularities in traffic, you would expect fairly similar patterns over time but graphs like this suggest something else at work. Outside of someone directly testifying to underhanded activities, it is difficult to imagine more damaging evidence than graphs like these.

Fighting to protect Chicago’s parks from mini-banks, tea stores, and the Lucas Museum

Curbed Chicago sets up the likely coming battle over using public space for the Lucas Museum:

Since late Spring, a small “pop-up bank” operated by PNC Bank has sat in Grant Park. It’s a bright orange and blue shipping container with doors and windows and an ATM. The park district earns $120,000 annually from the small structure, but many folks are not happy with its location in the park. DNAInfo has reports of numerous complaints about the very idea of a bank opening “It seems to go against the nature of the park itself,” a citizen tells DNAInfo.

The Park District is okay with it, obviously, in part because of the payola but also because, according to them, it’s not a permanent structure. In their mind, it’s a temporary vendor like you might find several dozen of in the park during Taste of Chicago. But is it the same? And where are the limits? What if Starbucks wants to open a mini-cafe right next to the PNC to capture the millions of visitors Grant Park will receive this summer? Why wouldn’t they?…

And consider Connors Park, to the north of downtown a few blocks from John Hancock tower. The squat little park is now home to an Argo Tea pavilion which just celebrated its one year anniversary of the location. Initially there was confusion about whether the park was still a park, and if it was okay to sit and enjoy the park without buying a tea. At a celebration for the one year anniversary, staff told us that with recent changes to the signage that confusion has dissipated and that neighbors know they’re welcome…

But the fact that these two issues are even issues at all speaks to the city’s constant vigilance against abuse of the parks, and it explains why despite being a seeming “slam dunk,” the Soldier Field parking lot location chosen for the Lucas Museum won’t come without a fight. This isn’t a quarter-block tea house or a 160 square-foot mini-bank, it’s a massive, multi-million-dollar development that has already captured the attention of the nation. As Chicagoist puts it, The Debate Over The Lucas Museum Has Only Started.

There are two levels to this:

1. What seems like an increased interest in many cities in ensuring that public spaces stay public. What can happen in these parks? Is there enough public space as opposed to private space masquerading as public space?

2. The special circumstances in Chicago that suggest the land near the lake needs to remain for public use. All sorts of ideas can pop up for a lakefront – I was reminded again recently about the older Mayor Daley’s suggestion that Chicago should build a major airport out in Lake Michigan – so having these guidelines has been a big boon. Yet, it is hard for a city that is chasing elite status (perhaps due to its own insecurity) to turn down a figure like George Lucas in such a location. Additionally, such a battle could give opponents of Rahm Emanuel an excuse to pick a battle.

Maybe all this represents one of the major trade-offs in today’s world: just how much do want corporate interests or the interests of powerful people overrule the rights of others? Constructing a museum like this isn’t the end of the world for Chicago but it may seem like another event in a long line of concessions to growth machines.

Chicago to collect big data via light pole sensors

Chicago is hoping to collect all sorts of information via a new system of sensors along main streets:

The smooth, perforated sheaths of metal are decorative, but their job is to protect and conceal a system of data-collection sensors that will measure air quality, light intensity, sound volume, heat, precipitation, and wind. The sensors will also count people by observing cell phone traffic…

While data-hungry researchers are unabashedly enthusiastic about the project, some experts said that the system’s flexibility and planned partnerships with industry beg to be closely monitored. Questions include whether the sensors are gathering too much personal information about people who may be passing by without giving a second thought to the amount of data that their movements—and the signals from their smartphones—may be giving off.

The first sensor could be in place by mid-July. Researchers hope to start with sensors at eight Michigan Avenue intersections, followed by dozens more around the Loop by year’s end and hundreds more across the city in years to come as the project expands into neighborhoods, Catlett said…

While the benefits of collecting and analyzing giant sets of data from cities are somewhat speculative, there is a growing desire from academic and industrial researchers to have access to the data, said Gary King, director of the Institute for Quantitative Social Sciences at Harvard University.

The sort of data collected here could be quite fascinating, even with the privacy concerns. I wonder if a way around this is for the city to make clear now and down the road how exactly they will use the data to improve the city. To some degree, this may not be possible because this is a new source of data collection and it is not entirely known what might emerge. Yet, collecting big data can be an opaque process that worries some because they are rarely told how the data improves their lives. If this simply is another source of data that the city doesn’t use or uses behind the scenes, is it worth it?

A quick hypothetical. Let’s say the air sensors along Michigan Avenue, one of Chicago prime tourist spots, shows a heavy amount of car exhaust. In response to the data, the city announces a plan to limit congestion on Michigan Avenue or to have clean mass transit. This could be a clear demonstration that the big data helped improve the pedestrian experience.

But, I could also imagine that in a year or two the city hasn’t said much about this data and people are unclear what is collected and what happens to it. More transparency and clear action steps could go a long way here.

Fighting over the fate of the Lathrop Homes, one of the remaining public housing projects in Chicago

While Chicago’s public housing high-rises (like Cabrini-Green) have been torn down, there is a current debate about the fate of the Lathrop Homes:

Lathrop’s two-story row houses and three- and four-story walk-ups occupy 35 acres on the western edge of Lincoln Park, and are often noticed by passersby on Diversey owing to the thick, white plumes of steam that rise from ground vents like jets from primordial geysers—the result of aging heating pipes. When the 925-unit development opened in 1938, it was one of the first public housing developments in the country and only the second in Chicago, built by a dream team of architects for the Public Works Administration’s New Deal program. For 30 years it was one of four all-white public housing projects managed by the Chicago Housing Authority. When the first African-American families were finally allowed to move into Lathrop in the late 1960s, they were segregated in the buildings on the south side of Diversey. The project didn’t become the melting pot Suarez describes until the 1970s…

Though Lathrop was supposed to be rehabilitated—and to remain 100 percent public housing—the CHA’s position shifted over the years. In 2000 the CHA stopped accepting new residents (in anticipation of rehabbing the property), and each subsequent year families were encouraged to move out. The buildings were shuttered one by one as Lathrop shrank from 747 occupied units in 2000 to about 140 today.

In other words, at a time when affordable housing in Chicago was becoming more and more scarce, hundreds of low-rent apartments were sitting vacant in a prime neighborhood.

In 2006 the CHA announced that Lathrop would become a mixed-income community with 400 public housing units, 400 tax-credit-subsidized units, and 400 market-rate ones. Demolition was scheduled for 2009.

But the housing market collapse, the recession, and persistent leadership turnover at the CHA has stalled those plans. To this day, not a single one of Lathrop’s 30 buildings has been demolished.

Interesting read about a project that is on the National Register of Historic Places and doesn’t get much attention despite some unique features. The story of the slow-moving CTA is not unusual; that has been the story for decades and it is understandable why residents aren’t always optimistic about better outcomes.

Man fills Chicago potholes with mosaic art

Chicago has had plenty of potholes in recent months and one man has taken to filling a few potholes with art:

The perfect pothole might not exist for many people — but for mosaic artist Jim Bachor, it’s one with a nice oval shape. Bachor began filling those potholes a little more than a year ago, after one in front of his house became a hassle.

Bachor doesn’t just fill them with cement, though. He’s turned pothole-filling into a public art project — one with a sense of humor. He fills them with mosaics.

“I just think it’s fun to add that little bit of spark into (an) issue that people moan about,” says the Chicago resident, whose work also hangs in galleries. He was first drawn to the ancient art form because of its ability to last.

With orange cones and vests displaying his last name, Bachor and his helpers look official enough to shut down a street section to work on filling a pothole.

Bachor uses the Chicago city flag design in his pothole art. Some versions hold phone numbers to local auto repair shops, while others simply read “POTHOLE.” His most recent installment north of downtown Chicago — “(hash)21914” — pokes fun at the huge number of potholes that exist in the city.

Public art that also helps the city fulfill one of its basic duties. How long until he is shut down for not filling potholes to standards or because it leaves the city liable?

It would be interesting to test the durability of mosaics in potholes. Given their construction with numerous small pieces, wouldn’t they be particularly susceptible to pressure, water, and freezing? I suspect there are much better ways to address potholes but they may not look as good or have any moxie.

Chicago to get its own “Carmageddon” on the Kennedy in June

Major repair work on the Kennedy in June is being dubbed Chicago’s own Carmageddon:

Chicago-area drivers are being urged to steer clear of the downtown stretch of the Kennedy Expressway during the last three weekends in June, officials said Thursday. That’s when bridge demolition on the Kennedy interchange at Ohio and Ontario streets will require shutting down expressway lanes, first in the inbound direction, then outbound and finally the Ohio and Ontario feeder ramps…

Officials hope the stern warning will help prevent hourslong snarls along the expressway that carries an average of 260,000 vehicles a day, avoiding what some traffic engineers have referred to a “carmageddon.”…

The work to tear down sections of the bridge, drop the concrete pieces onto the Kennedy and haul away the debris is scheduled for a series of tightly choreographed 55-hour periods on the weekends of June 13-15, June 20-22 and June 27-29, according to IDOT plans…

On an average project, IDOT tries to “scare away’’ 15 percent of the traffic to compensate for lane closures, officials said. During the Kennedy work, they hope to divert about 25 percent of traffic elsewhere.

There are echoes here of the Carmageddon in Los Angeles several years ago that ended up working out pretty well. While this location is a key part of the Chicago highway system, there are alternative routes either in the downtown area or different highways that can route people further around the city. At the same time, this does highlight the importance of fixing the Circle Interchange nearby to have better traffic flow.

It will be interesting to watch the PR for all of this. In fact, is two weeks enough time to start alerting people to Chicago’s own Carmageddon? Yet, I imagine local news outlets will eat this up.

Chicago second in nation, fifth in world for Starbucks

Chicago is a world leader in Starbucks, even if it is sometimes insecure about its place on the world stage:

Chicago is home to 164 Starbucks, ranking the city second in the United State behind New York City–and fifth in the world, according to Starbucks store data compiled by Chris Meller.

There are 64 locations in an area bounded by DesPlaines, Oak Street, Congress Parkway and Navy Pier. That’s 40 percent of the city’s total…

At O’Hare International Airport alone, there are 17 Starbucks locations, including spots in baggage claims, terminal concourses, food courts and near gates.

The South Side has only nine stores south of 33rd Street. There are no Starbucks on the West Side–at least none west of Ashland.

The common factors behind the Chicago locations seem to be the wealth and number of tourists in different locations. In other words, Starbucks tends to locate where there are more people with more money to spend on coffee. This may be a little different than the vision the store promotes for serving as a “third place” – these third places are for certain kinds of neighborhoods.

Designing Chicago to provide a better video game experience

Making Chicago the setting of the new video game Watch Dogs includes changing the city to improve the gaming experience:

He described the basic creation of Chicago this way: “Essentially we started with a top view of Chicago, the actual Chicago map, which we put in our game editor, and from there we carved into it. It’s a big, empty space at first. So we start laying out roads by going with the real road and adjusting from there, making sure, for instance, that Wacker follows the river correctly, but adjusting a bit too. You also make sure roads connect properly, but we didn’t go with the Chicago grid because it was so straight, too many right angles. It’s better for the game play if you can’t see far ahead of yourself. So we curve things. Once the roads are laid down and the city reduced, you went street by street putting in neighborhoods, landmarks …”

Like many an open-world video game city, building the open-world Chicago of “Watch Dogs” became a dance between game play, accuracy and urban planning. In general, what Arriola described is the same process that created cities in “Saints Row” and “Grand Theft Auto”: Four-lane roads became six lanes to encourage driving (nobody likes digital gridlock, either), buildings were pressed together to encourage rooftop-to-rooftop leaping and only the most visually unique neighborhoods survived (albeit incongruously, mashed up against other neighborhoods).

“An open-world city in a good video game is a riff on a city, not a city,” said Brian Schrank, co-chairman of the game development program at DePaul University. “It’s a little exploitative, a little like a remix of familiar elements. You are seeing a suggestion of unending choices, but in reality a game developer is being subtle and laying out the breadcrumbs that pull you through their city.”

Hence, the isle of Chicago.

The Chicago River needed widening, and the Northwest Side needed geographic diversity, so, in the game, the north edge of the Gold Coast becomes actual coastline, the farthest northern point in this Chicago. A player can pilot a boat from the lake and around the downtown area without hitting a dead end.

See this earlier post about using Chicago in the new game.

This isn’t just the issue of creating a copy of the city of Chicago. That in itself could be interesting and/or jarring, seeing a faithful reproduction on the screen but being able to do things the average resident or visitor could not. But, this goes a step further to “improve” the city for the gamer. One way to think about it is that the city is not compelling enough as it is but needs to be tweaked to allow for features that gamers expect like easy yet unclear driving and using a boat. The isle of Chicago? A grid system of street that now curves? Urban sociologists and other urbanists are often drawn to big cities because of their dynamism – from social interactions to culture to architecture, to economic and political activity – that is plenty interesting without tweaks.

The gamification of the world continues, with the big city as yet another victim…

Presenting big data about Chicago

The Chicago Architecture Foundation has a new exhibit highlighting the use of big data in Chicago:

Architects, planners, engineers and citizens, it contends, are increasingly using massive amounts of data to analyze urban issues and shape innovative designs…

But data, the show argues, is useful as well as ubiquitous. We see some classically gritty Chicago stuff to back this up, though it’s not quite powerful or precise enough to be fully persuasive…

More convincing are the show’s examples of “digital visualization,” which is geekspeak for using digital technology to present and analyze urban planning data.

Take a monumental, crowd-pleasing map of Chicago, 15 feet high and 30 feet wide, which presents the footprints of thousands of buildings, even individual houses, and color-codes them by the era in which they were built. We see the impact of the city’s three great building booms, from Chicago’s earliest days to 1899, from 1900 to 1945, and from 1946 to 1979. The recent surges that filled downtown with new skyscrapers look puny by comparison.

Also worth seeing: Video monitors which display data for Divvy, the city’s bike-sharing program. They offer neat tidbits: Divvy’s most popular station, for example, is at Millennium Park.

Sounds interesting. Big cities are complex social entities who could benefit from large-scale and real-time data collection and analysis. Of course, as Kamin notes at the end, there still is a human side to cities that cannot be ignored but getting a handle through data on what is happening could go a long way.

Another dimension to this is how to best present big data. While the online presentation of maps has grown popular, how can this be done best in person? I look forward to seeing this exhibit in person as I already like what the Chicago Architecture Foundation has done with this space. Here is part of the gallery a few years ago:

CAFChicagoAug11This is a great free place to learn more about Chicago and then choose among the cool offerings in the gift shop or sign up for one of the architecture tours that cover all different aspects of Chicago.

Chicago stars in the new video game Watch Dogs

Curbed Chicago looks at how the city is portrayed in the new game Watch Dogs:

Chicago is finally getting a starring role in a new video game. New York, LA and Miami have all made cameos in the popular Grand Theft Auto series, but a new game called Watch Dogs will take place in an Orwellian version of Chicago. Although the scale and placement of buildings is not completely accurate, the graphics are quite surprising and this semi-fictional city depicted in the game definitely looks like our fair city. Some of the Chicago icons spotted in this promo video include famous buildings like the Willis Tower, the Trump Tower, the John Hancock Center, the Aqua Tower, and Marina City.

The pictures look pretty accurate.

So why doesn’t Chicago get more video game love? Do other American cities have glitzier and more worldly facades that are well-suited to garish video game scenes or dystopian scenes? Maybe all that Midwestern charm, winter weather, and gleaming International style architecture simply isn’t entertaining enough. Chicago may be the #7 global city but not necessarily for video game purposes.
