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.

SFO airport showed me some cool planes

March 18, 2013 / / 0 Comments

I flew on Virgin American to Portland, Oregon, last year and had to stop in San Francisco on my return journey to Chicago. The layover was over 2 hours long, and I spent that time relaxed in the new Terminal 2. The terminal has great window coverage of the airfield.

I saw for the first time an Airbus A380, the largest of the so-called jumbo jets (is that phrase even used anymore?). It was flown by Lufthansa (see photo).a

I also saw a lot of Boeing 747s from different airlines, including United, OneWorld, Star Alliance, British Airways, and Cathay Pacific. I may have seen a Chinese airline.

I also saw President Barack Obama land in Air Force One. I recognized the plane from far away, as it was coming in for landing, but I wasn’t completely sure until it touched down. My camera was probably hanging around my neck; I was too dumbstruck to do anything about it. After it landed and I was positive that Boeing 747 was flown by the United States Government, I walked around the terminal until I could see it.

The plane had been parked far away from a terminal, near a hanger and two C-17 military cargo planes.

American airports should have viewing platforms. Not just plane spotters like to photograph them. Amsterdam Schiphol (AMS) airport has a viewing platform and there was over 50 people up there, including lots of families.

What modernism should we preserve?

March 7, 2013 / / 0 Comments

Ed. note: This post is written by Ryan Lakes, friend and architect. 

Goldberg’s Marina City towers are a couple of my favorite buildings in Chicago, but all of the discussion about preserving Prentice Women’s Hospital – designed by Bertrand Goldberg – has left me conflicted. The following is my response to the video above that was originally posted on Black Spectacles.

When we figure out how to easily move old, significant buildings that are no longer wanted by their owners and occupants, to museum-cities made up of the old masterpieces that have since fallen out of use or favor, then we will have the luxury to preserve them like books, paintings and sculptures. To me, large buildings are more like trees than art. Occasionally the great old fall to make way for the young. There is no moving them. And as time passes, individual systems age and decay, and evolution leads to new, often more efficient ways to compete for space and resources.

Contemporary architecture has a new set of more complex criteria to respond to than what was included in original modernism’s scope. With form ever following function, in modernism, as functions change, so too shall the forms. Is modern architecture able to do so? How do fans of modernist buildings plan to preserve them as fuel prices rise and the desire for energy efficient buildings increases?  What else besides their structure is not obsolete? Let’s not forget that the time of modernism was when most thought our resources were unlimited, that it was better to leave our lights on 24 hrs a day to save bulbs, and that it was better to employ machines to fabricate our buildings rather than our neighborhood craftsmen.

Talking about a pedestrian street for Peoria Street on Vocalo

March 1, 2013 / / 2 Comments

Click on the rendering to enlarge and learn about the main features. 

Ryan Lakes and I took our Peoria Street pedestrian street proposal to the masses by speaking to Molly Adams and Brian Babylon on Tuesday morning’s Morning AMp show on Vocalo, FM89.5

Listen (or download) to the 15 minute interview on SoundCloud. 

What is the Peoria Street pedestrian street?

We propose creating a gateway connection between the University of Illinois at Chicago’s east campus and the West Loop neighborhood over the Peoria Street bridge by nearly eliminating car traffic, completely eliminating parking, removing curbs, and adding amenities to make this a place to go to instead of through.

The Peoria Street bridge over I-290/Eisenhower expressway, between Van Buren and Harrison Streets, was closed to car traffic in 1965 when a new entrance for the CTA station opened. This entrance of the UIC-Halsted Blue Line station is by far the most used access point to the busy station, as it’s the closest to campus buildings. In fact, according to a CTA letter to IDOT, “weekday passenger volumes at this station entrance exceed 11 of the other 12 total station passenger volumes at the other stops on the Forest Park Blue Line branch”.

The UIC Campus Master Plan of 2010 calls for creating a gateway at this place, and the Illinois Department of Transportation is proposing to rebuild this bridge as part of its Circle Interchange project. The bridge should rebuilt to accommodate a pedestrian street. However, rebuilding isn’t necessary and our proposal can be implemented in situ.

How many miles of roads are in your ward?

February 27, 2013 / / 10 Comments

Screenshot 1: Showing how some streets are not being counted. There should be a yellow section of road between the two existing yellow road sections. 

A friend recently asked me how many blocks of road are in his ward. He wanted to know so that he could measure how many blocks of streets would have an older style of street lighting after X number of blocks receive the new style of street lighting. For this project, I used two datasets from Chicago’s open data portal: street center lines and wards. The output data is not very accurate as there may be some overlap and some uncounted street segments; this is likely due to a shortcoming in my process. I will show you how to find the number of blocks per ward using QGIS (download Quantum GIS, a free program for all OSes).

Here’s how I did it

  1. Load in the two datasets. Wards and street center lines (zipped shapefiles). They are projected in EPSG:3435.
  2. Exclude several road classifications in the street center lines by querying only for "CLASS" > '1' AND "CLASS" < '5'. The data dictionary for the road classifications is at the end. We don’t want the river, sidewalks, expressways, and any ramps to be included in the blocks per ward analysis.
  3. Intersect. In QGIS, select Vector>Geoprocessing Tools>Intersect. The input vector layer is “Transportation” (the name of the street center lines dataset) and the intersect layer is “Wards”. Save the resulting shapefile as “streets intersect wards”. Click OK. This will take a while.
  4. Add the “streets intersect wards” shapefile to the table of contents.
  5. You’ll notice some of the issues with the resulting shapefile: missing street segments (see screenshot 1). What should QGIS do if a street is a ward boundary?
  6. Obtain street length information, part 1. Remove all the columns in the “streets intersect wards” shapefile that have something to do with geometry. These are now outdated and will confuse you when you add a geometry column generated by QGIS.
  7. Obtain street length information, part 2. With the “streets intersect wards” shapefile selected in the table of contents, select Vector>Geometry Tools>Export/Add geometry columns. Select “streets intersect wards” shapefile as your input layer, leave CRS as “Layer CRS” and save as new shapefile “streets intersect wards geom”.
  8. Add the “streets intersect wards geom” shapefile to the table of contents.
  9. You will see a new column at the end of the attribute table called LENGTH. Since the data is projected in EPSG:3435 (Illinois StatePlane NAD83 East Feet), the unit is feet.
  10. Simply export “streets intersect wards geom” to a CSV file and open the CSV file in a spreadsheet application. From there you can group the data by Ward number and add the street lengths together. (I thought it would be faster to do this in a database so I imported it into a localhost MySQL database and ran a simple query, SELECT wardNum, sum(`chistreets_classes234`.`LENGTH`) as sum FROM chistreets_classes234 WHERE ward > 0 group by wardNum. I then exported this to a spreadsheet to convert feet to miles.)

Because of the errors described in step 5, you shouldn’t use this analysis for any application where accuracy is important. There are road lengths missing in the output dataset (table with street lengths summed by ward) and I cannot tell if the inaccuracy is equally distributed.

[table id=7 /]

Wards 19 (south side) and 41 (Norwood Park, including O’Hare airport) have the highest portion of street length in the city.

Screenshot 2: Ward 41 is seen. 

Street data dictionary

Column is “CLASS”. The value is a string. This dataset lacks alleys. Adapted from the City’s data dictionary.

1. Expressway

2. Arterials (1 mile grid, no diagonals)

3. Collectors (includes diagonals)

4. Other streets (side streets, neighborhood streets)

5. Named alleys (mostly downtown, like Couch Place and Garland Place)

7. Tiered (lower level streets, including LaSalle, Michigan, Columbus, and Wacker)

9. Ramps (goes along with expressway)

E. Extent (not sure how to describe these; includes riverwalk and lake walk segments, and Navy Pier, also includes some streets, like Mies van der Rohe Way)

RIV. River

S. Sidewalk

99. Unclassified
