Tell me I’m wrong with my Parking Meter Deal Part Deux calculations

I want nothing more than to believe Mayor Rahm Emanuel has created a good deal but I believe his own parking meter deal is just as ridiculous as the deal – from Richard M. Daley and 45 aldermen – that preceded it.

Rahm’s deal changes none of what Chicagoans abhor about the current deal, which include:

  • It scheduled many price increases, without offering the buyer, those who pay to park, any additional value. Value could come in the form of a parking benefit district, where the revenues pay for local infrastructure improvements.
  • The city gets none of the revenue (it collects fines, though).
  • It costs us more than we ever expected (disabled parking placard, reimbursement for street closures, road work, and festivals).
  • It removes control from the city administration and aldermen over our streets. Thanks goes to Active Transportation Alliance for pointing this out in their excellent June 2009 original report (since retracted and revised) in which the organization said, “As a result [of the lease], planners and neighborhoods have lost control over one of their most powerful urban planning and revenue generating tools.”

It changes nothing that policy makers dislike about it:

  • We can’t implement dynamic or market or congestion pricing, unless the revenues for CPM stayed the same or were increased (although this would have to be negotiated).
  • It throws another cog into the city’s plans to expand bike lane mileage. We’re already having a difficult time with merchants not wanting to lose parking in front of their store, despite all the evidence pointing to bike lanes increasing revenues. To make way for a bike lane, the metered parking space has to be moved to an equally valuable spot within the same Parking Region. The alderman has to get involved and it’s not an easy process.

Rahm’s deal, which the city council must approve as an ordinance, doesn’t help Rahm’s priorities.

The Active Transportation Alliance report said, “This lease agreement [from 2009] compromised the city’s ability to adjust parking policy; because of the agreement terms, meters will be the primary consideration in the planning of our city streets. Everything else, from traffic flow to pedestrian, bicycle and transit facilities may only be considered after meters and their corresponding income has been considered.”

Rahm’s new deal doesn’t change that, but in fact will likely give CPM the same or more revenues under the plan. It will reduce the chargeable hours by 12 hours on one day (the newly free Sunday) and increase by 1 hour at more valuable times (weekday and weekend evenings) in areas that charge $2 and $4 per hour, and is increased by 3 hours at the same times in areas that charge $6.50 per hour. I’ve attempted to estimate how much more revenue with the spreadsheet below.

The city isn’t saving $1 billion – it hasn’t spent that money and there was no surety that it would; the press release acknowledges this, calling them ” estimated future charges”. The point here is that CPM and the city have agreed on how things like street closures and disabled parking placards will be paid for (by the city). CPM isn’t going to agree to any deal that reduces the value of the company to its shareholders.

No one asked to have free parking on Sunday. No one asked to have free parking on any day. Sunday is the day when people drive the least! If anyone deserves a break, it shouldn’t go to a small segment of the popular (“Sunday churchgoers”, Rahm said, acting as if they’re being harmed, and excluding churchgoers who don’t attend on Sundays), but to everyone who had to pay more than the parking space was worth and anyone who couldn’t get a bike lane in while people are being doored left and right.

Why else is free parking a bad idea? The experts at Active Transportation Alliance wrote:

Underpriced curb parking is a hidden source of traffic congestion and stimulates the most inefficient form of urban transportation. Underpriced parking encourages drivers to cruise for cheap parking, which harms everyone’s health and safety, slows down automobiles and buses behind the cruiser, and provides little benefit to the cruiser. It is a danger to bicyclists and pedestrians because cruisers focus on finding the right spot, not on whether a pedestrian is crossing the street.

It’s this last point, the lack of focus on anything but the parking spot, that is believed to be the cause of a cyclist being severely injured last week on Milwaukee Avenue.

Just like Daley, Rahm didn’t consult the one alderman whose ward might be affected most (it’s unknown if any aldermen were consulted). If this trend of the current city council being the most “rubber stamping” in all time (by my favorite local blogger Whet Moser), I predict it’ll be passed.

Calculations

[table id=8 /]

Since the number of spaces doesn’t change between the old and new scenarios, there is no need to calculate the total $ per space per region. Revenue estimate assumes the space is always occupied. In the new scenario, proposed by Rahm Emanuel and CPM, all spaces not in neighborhoods have become slightly more valuable, enough to more than make up for the reduced value of spaces in neighborhoods.

Updated May 3, 2013, 15:51 to add a link to the current version of Active Transportation Alliance’s parking meter report and to say that it replaced the original report. 

BikeSpike has major potential impact for data collection

March 19, 2013 / / 8 Comments

This is a pretty hilarious video showing the main reason one would get a BikeSpike: to catch a thief. 

Bill Fienup emailed me in December or January asking to meet up to talk about their bike theft tracking device (that does a whole lot of other stuff) but I couldn’t meet until February as the transition from Grid Chicago to Streetsblog Chicago was occupying my brain time. Bill’s part of Team BikeSpike.

The BikeSpike in hand. It’s very small and weighs 3.1 ounces.

It was convenient that they were at 1871 on a Tuesday night; I was there for Hack Night, they for one of the other myriad events that occurs on the 12th floor of the Merchandise Mart. They showed me a 3D-printed mockup of the BikeSpike, and told me what it was capable of doing. They seem to have a good programmer on their team in Josh Billions – yes, that’s his real last name.

I came to their lab near Union Park to talk in depth about BikeSpike with Bill, Josh, Harvey Moon, and Clay Neigher, garner more information, and provide them with some more insight into how the product can be useful to the transportation planning work I do as a Streetsblogger, advocate, and programmer. I brought my friend Brandon Gobel and he became interested to hear about how it could help him manage the future fleet of Bullitt cargo bikes he’s now selling and renting at Ciclo Urbano.

Beside the fact that BikeSpike can show law enforcement workers the EXACT LOCATION OF STOLEN PROPERTY, I like its data collection aspects. Like many apps for iOS (including Moves and Google Latitude), BikeSpike can report its location constantly, creating opportunities for individuals to track training rides and urban planners to see where people ride bikes.

Cities should know where people are riding so they can build infrastructure in those places! Many cities don’t know this until they either count them frequently and in diverse locations, or when they ask. But neither of these methods are as accurate as hundreds, or thousands of people reporting (anonymously) where they ride. I’ve got three examples below.

I imagine the BikeSpike will produce a map like this, which was created by Google Latitude constantly tracking me. 

Team BikeSpike: Clay, Bill, Ben Turner (I didn’t meet him), Josh, and Harvey.

1. Want to see if that new buffered bike lane on South Chicago Avenue actually encourages people to ride there and wasn’t just an extra-space-opportunity? Look at BikeSpike data.

2. The number of people biking on Kinzie Street shot up after a protected bike lane was installed. How many of these new Kinzie riders switched from parallel streets and how many were new to biking? Look at BikeSpike data.

3. Given relatively proximal origins and relatively proximal destinations, will people bike on a buffered bike lane (say Franklin Street or Wabash Avenue) over a protected bike lane (say Dearborn Street)? Look at BikeSpike data.

There are many other things BikeSpike can do with its GPS and accelerometer, including detect if your bike was wiggled or you’ve crashed. I want a BikeSpike but you’ll have to back the project on Kickstarter before I can get one! They need $135,000 more pledged by April 9.

Get out of Googleville: my presentation on web mapping

Alternate headlines: Google Maps versus OpenStreetMap; why OpenStreetMap is better than Google Maps

I presented to the Chicago GIS Network Meetup group on February 5,2013, about alternatives to Google when it comes to mapping on the web. I created the presentation and outline a couple hours before giving it and came up with this slideshow with three frames.

Googleville 1 of 3

Google Maps and its data is a one-way street (or many one-way streets). Google will take data but won’t give it back.

Googleville 2 of 3

Google Maps has all of these features, but they’re easier to manipulate when you use an alternative. Alternatives like: MapBox, TileMill, OpenLayers, OpenStreetMap (made easy with JOSM), GeoCommons – I’m sure there are plenty more.

Googleville 3 of 3

OpenStreetMap is the Wikipedia of online mapping and geographic data. Considering switching to OSM.

Tell it, Sue Baker! Car crashes are not accidents

October 29, 2012 / / 0 Comments

“It was an accident!”, said the driver. Photo by Katherine Hodges. 

Because of Hurricane Sandy, the New York Times paywall is down so I’m reading every article I can, starting with “Safety Lessons from the Morgue“:

As she explains it, “To say that a car crash is an accident is to say it’s a matter of chance, a surprise, but car crashes happen all the time, and the injuries that people sustain in those crashes are usually predictable and preventable.”

Another car crash-related excerpt from the article about Sue Baker, injury prevention researcher extraordinaire:

In one of her recent projects, Baker looked at another aspect of highway deaths. The study, which Baker prepared with David Swedler, a doctoral candidate, examined more than 14,000 fatal crashes involving teenage drivers. They found that male drivers were almost twice as likely as female drivers to have had high levels of alcohol in their blood and were also more likely to have been speeding and driving recklessly. Significantly, 38 percent of 15-year-old drivers, both male and female, were found to have been speeding, but by age 19, female speeders dropped to 22 percent, while male speeders remained steady at 38 percent.

Those differences, Baker says, suggest that boys and girls should not automatically receive the same driver training — and that boys should perhaps receive their license at an older age than girls. “Males might scream foul,” Baker acknowledges, “but let them.”

Yes, let them. It’s too easy to get a driver’s license in this country.  I love her style:

In 1979, at a Department of Transportation public hearing about the dangers faced by truck drivers, Baker angrily explained, “Isn’t it time we did some crash testing with trucks and dummies, rather than with drivers themselves?” Later, according to Baker, the trucking industry hired a researcher to try to discredit her driver-safety studies. Unable to uncover problems with her work, he eventually gave up and called to tell her about his assignment. [emphasis added]

Not everything is perfect with injury prevention studies, though.

In the mid-1970s, [Sam] Peltzman did research on highway fatalities that suggested that mandatory safety features like seat belts and padded dashboards actually encouraged people to drive less cautiously.

Tom Vanderbilt talked about that in “Traffic“, which is basically my favorite transportation book, even mentioning Mr. Peltzman. Flip to page 181 to read it. Vanderbilt lists all of the different labels for that behavior:

  • the Peltzman effect
  • risk homeostasis
  • risk compensation
  • offset hypothesis

He summarizes: “What they are saying, to crudely lump all of them together, is that we change our behavior in response to perceived risk, without even being aware that we are doing so”. But Sue has a response:

Baker acknowledges that there may be some individuals in cars with anti-lock brakes, for example, who may not apply the brakes as soon as they did with the old brakes. But she insists there is no evidence that better brakes or air bags have encouraged recklessness — that they have in fact saved many thousands of lives. “What concerns me,” she says, “is that these spurious arguments are used by companies to bolster their opposition to beneficial safety regulation.

I think it’s safe to say now that she’s a personal hero of mine. But way, there’s just one more thing!

As she talked about what still needed to be done, her voice was tinged with anger: “Buildings need to be designed so it’s not so easy to fall down stairs. All new homes should have sprinklers. Traffic lights should be timed for pedestrians, not to move as many cars as possible through an intersection.

Yep. Exactly what we don’t do. We make ’em wait. And wait. Without even telling people the traffic signal’s even acknowledged their presence.

Links between pedestrian safety and crime

October 25, 2012 / / 4 Comments

Chicago Pedestrian Plan

Safety item 20: Analyze the relationship between pedestrian safety and crime (download the plan)

The 2011 Chicago Pedestrian Crash Analysis identified a strong correlation between community areas with high numbers of pedestrian crashes and community areas with high crime rates. Correlation does not indicate causation and further study is necessary to understand this relationship and the potential broader benefits of pedestrian safety improvements. [From page 62 in the 2012 Chicago Pedestrian Plan.]

ACTIONS

Short Term

  • Identify and obtain funding for this study.
  • Identify a location for safety improvements and obtain data for the “before” conditions.

Mid Term

  • Design and implement pedestrian safety improvements.
  • Develop a pedestrian safety enforcement plan for the area for the duration of the project.
  • Analyze the effects on pedestrian safety and crime.

MILESTONES

  1. Initiate this study by 2013 and complete by 2015.

Pedestrian Crash Analysis

The summary report didn’t contain the word “crime”. The technical report contained 2 mentions, with an additional chart. They are quoted in the ordered list below. Download the summary report.

  1. In an examination of various factors including crime, income, race, language spoken, and Walk Score®, the strongest correlation found was between pedestrian crashes and crime
  2. Finally, crime statistics were compared to pedestrian crashes to determine if a correlation could be identified, using data from the Chicago Police Department (CPD) annual reports for 2005 through 2009. The annual reports include incidences of crime by Chicago Community Area (CCA). The statistics for the years 2005 through 2009 were averaged and compared to the aver- age number of fatal and serious injury pedestrian crashes over the same time period in each CCA. Of these factors, crime was the only variable that correlated to pedestrian crashes. Figure 1 shows the correlation between crime and pedestrian crashes was very high. However, there may be many variables responsible for this correlation.
  3. Figure 1: Crime vs. Fatal and Serious Injury Pedestrian Crashes by Chicago Community Area

Figure 1.

I have a few criticisms of this analysis: it lacks raw data; the data tables included in the technical report are of limited length, listing only the “top” items of any metric; the summary report lists many silly factoids; the maps are low resolution and of a limited scale – their design could be modified to improve their usefulness in communicating the crash frequencies of the marked locations. The analysis is reliable.

The technical report includes the state’s guide on how police officers are trained to fill out a crash report form. It also includes relevant crash reporting laws in Illinois. Download the technical report.
