Obtaining Chicago Transit Authority geodata

October 12, 2010 / / 0 Comments

A reader asked where they could get Chicago Transit Authority (CTA) data I didn’t already have on the “Find GIS data” page. I only had shapefiles for train lines and stations. Now I’ve got bus routes and stops.

You can download General Transit Feed Specification (GTFS) data from the CTA’s Developer Center. It’s updated regularly when service changes.

Screenshot from ESRI ArcMap showing the unedited shapes.txt file loaded via Tools>Add XY Data. Shapes.txt is an 18 MB comma-delimited text file with thousands of points that can be grouped together with their shape_id.

The GTFS has major benefits over providing shapefiles to the public.

  1. It can be easily converted to the common shapefile format, or KML format.
  2. Google, the inventor of GTFS, has defined and documented it well; it is unencoded and plaintext. These attributes make it easy for programmers and hackers to manipulate it in many ways. (see also item 4)
  3. Google provides a service to the public on its website, an easy to use and robust transit planning service.
  4. The data is stored as plaintext CSV files.
  5. While an agency like CTA may have a geodata server on its intranet, it is less likely it has the addons that provide mapping and geodata services for the internet. A server like Web Mapping Service, or ArcIMS. These systems can be expensive to purchase and license. And we all know how the CTA seems to always be in a money crunch. While the CTA updates its GTFS data for publishing to Google Maps, the public can download it simultaneously to always have up-to-date information, providing the same geodata that ArcIMS or WMS would offer but for no additional cost.

I couldn’t have pulled off this conversion in 24 hours without the help of Steven Romalewski’s blog, Spatiality. He pointed me to the right ArcMap plugin in this post about converting the Metropolitan Transportation Authority’s GTFS data into shapefiles. I hope Steven doesn’t move to Chicago less my authority on GIS and transit be placed in check!

Make your own map of the CTA train routes and perform some kind of analysis – then share it with the rest of us!

Park wins while parking fails neighborhood

October 8, 2010 / / 0 Comments

This post on the removal of car parking at a park inspired me to write this post about the addition of car parking at a park.

Palmisano (Stearns Quarry) Park was created out of a dolomite limestone quarry and landfill in Bridgeport. The park is well designed and has a variety of landscape features. It’s quite popular, especially with elderly Asian residents.

Now, after a year of it being open, many diagonal parking spaces were installed on 27th Street. Space was removed from the parkway to create additional parking spaces where only parallel spaces existed.

Access to the park is not an issue. There are hundreds of households and thousands of residents within half a mile. There’re bike lanes and bus stops. There is a signalized intersection that makes it safer for people to cross the street to the park. Lastly, there are many unused parallel parking spaces lining two sides of the park.

So why was parking added? Did the neighbors ask for it? Did the Chicago Park District feel new parking was needed?

In a nutshell, my complaints against this are:

  1. It removed parkway – this should be sacred space. Perhaps we can institute a “tit-for-tat” policy (modeled after a parking meter agreement*) where if parkway is removed in one place, parkway has to be expanded or improved in another place.
  2. Potentially increases traffic in area by encouraging more driving by offering free parking. All parking surrounding the park is free.
  3. Parking space for drivers with handicap badges does not have a ramp. This is the most perplexing part – you may have to open the photo to its full size to notice this.
  4. Bumpout is not a bioswale. I highly doubt anyone will maintain the grass and soil. This landscaping will die.
  5. Bumpout’s large radius will not calm traffic (I watch it every day).

I would like to see the bumpout “island” transformed into a proper curb extension at a stop sign where drivers typically pause in the crosswalk and quickly turn right into southbound Halsted without stopping. I would like to see a bioswale collect the water from the street at this curb and divert it to the park’s wetlands.

*As I understand it, if parking meter spaces are removed and converted to another use (like a curb extension or on-street bicycle parking), a non-metered space must be converted to the equivalent metered spaces removed.

Metra 35th St. station surely won’t win any design awards

October 7, 2010 / / 0 Comments

UPDATE 04-07-11: The station opened on April 3, 2011. Blair Kamin explains why it doesn’t look as good as originally designed:

It didn’t have to be this way. The Chicago office of Skidmore, Owings & Merrill came up with a promising design for the station, one that justified the demolition of a Mies-designed brick hut that reportedly served as the entrance to an underground testing facility for explosives during the Cold War.

But then, things went seriously off the rails.

This new Metra commuter/regional rail station at 35th Street and Wentworth/Federal won’t win any design awards. Neither will the Lovana S. “Lou” Jones/Bronzeville Station stand out for having such a generic design.

The station under construction as of October 3, 2010.

The amount of visible concrete used in the stairs and ramps construction (one complete set on either side of the tracks) is fitting if you consider the station’s surroundings: a 12-lane highway (the Dan Ryan, I90/94), thousands of surface auto parking spaces to the west (for the White Sox stadium), and an empty lot.

But what if we looked for design inspiration from the east?

Imagine a station shelter modeled after the sound mitigation “tube” over the Illinois Institute of Technology McCormick-Tribune Campus Center a few blocks away at State Street designed by Rem Koolhaas.

Open letter to Blair Kamin about Safeway and Dominick’s

October 6, 2010 / / 0 Comments

Blair Kamin, the Chicago Tribune’s architecture critic wrote about the new LEED-certified Dominick’s* (Safeway) grocery store in Lincoln Square at Lincoln and Berwyn. This store features copious bike parking of a decent quality and design (see photo below).

In February 2009, I wrote a letter to the General Manager at their 3145 S Ashland store (read my letter). Someone at the company promptly made a request to the City of Chicago in March 2009 for a bike rack. The request was denied because the store is too far away from the nearest public right-of-way.

The following is my letter to Blair Kamin, John Hilkevitch (Tribune transportation writer), and the CEO of Safeway, Steve Burd.

Dear Blair,

I would like your help in getting better accommodations for bike riders at a local Dominick’s.

I read your article about the new, LEED-certified Dominick’s in Lincoln Square with copious bike parking available. (This should help with the potential auto parking issues you identified by encouraging people to bike to the store.)

The Dominick’s nearest me, at 3145 S Ashland, underwent major renovation in 2008 and 2009. People who ride their bicycles to the store (myself included) locked them to the shopping cart guard rails that were removed during renovation.

Bike parking was not included in this renovation.

LEED certification shouldn’t be the only impetus for installing bike parking. Currently it only gains the development 1 point and more than 40 are needed (more for Bronze, Gold, Silver, or Platinum). Installing bike parking should be an economic decision.

A single bike rack (holding two bikes) will cost less than $300 and require no maintenance for at least 5 years (some bike racks installed by the City are over 10 years old and look/work fine). A car parking space costs $1,000 per year to maintain.

We currently lock to garbage bins in a sheltered area near the store entrance. I ask that Dominick’s install real bike parking here in 2010. If they do, I’ll then ask them to work on the bike parking situations at their other stores (like the store at 1340 S Canal).

Thank you for your attention to bicycle infrastructure matters in Chicago.

P.S. The Dominick’s at 3145 S Ashland also has the unfortunate situation of being in a strip mall far away from any public roads. This precludes the City from installing bike racks; the nearest public space is more than 50 feet away.

Jewel…you’re up next!

The bike parking area at the new Dominick’s grocery store in Lincoln Square. Sure beats locking to a garbage bin at the Dominick’s at 3145 S Ashland in Bridgeport. That store underwent renovation in 2008 and 2009.

What bike parking at 3145 S Ashland looks like.

*The store is not yet LEED certified. Blair reports it’s expected to receive a Silver rating.

Proposed changes to 31st Street Harbor

October 5, 2010 / / 0 Comments

Copied directly from the 31st Street Harbor Traffic Impact Analysis (PDF), prepared for the Chicago Public Building Commission by AECOM.

See Exhibit B on page 12 for a drawing and list of proposed changes. They’re exciting. When designing for the lakefront, the stakes are pretty high.

The only mention of “bike” or “bicycle” is misnaming the Lakefront Trail as the “Chicago Lakefront Bike Path.” Can’t anyone get this right? According to the LEED Strategy document, though, the project aims to get 1 point for a “bicycle storage/changing room.”

Stay on top of construction updates with this blog.

The 31st Street Harbor project is one of two new harbors being designed for the Chicago Park District along Chicago’s lakeshore. Located in the Bronzeville neighborhood on Chicago’s south side, the 31st Street Harbor will incorporate extensive new community amenities and a new 950 slip marina. These include over two new acres of green space located on a peninsula of land formed by a 1,200 foot long breakwater sheltering the new harbor, providing exceptional views of the Chicago skyline to the north. The breakwater will also create new underwater habitat and provide opportunities for fishing.

Photo shows the new breakwater and pier under construction. See Exhibit B.

The existing surface parking will be removed and relocated within a new parking structure covered by an accessible green roof that allows park users improved views of the lake while reducing impervious surface. Landscape plantings will include native plants selected to provide food and cover for the twice yearly bird migrations through the City, while also reducing maintenance and irrigation demands. A new fully accessible play area that connects the green roof area to the beach will replace an older existing playground, while improvements to pedestrian and vehicular circulation will improve connections to the neighborhoods in Bronzeville to the west. Located atop the green roof will be a new LEED Certified community center and restaurant, providing sorely needed facilities currently missing along the south lakeshore.

The marina itself will include approximately 950 new slips ranging from 35’ to 80’ in length, on site covered storage in the parking structure, fuel dock, marina store, dedicated shower facilities, and a public access boat ramp. Additionally, youth sailing programs and storage for small craft including kayaks will be provided, allowing this facility to make boating economically accessible to a very large portion of the community.

As part of these improvements, additional parking accommodations in addition to the new parking structure are being planned. Approximately 200 new parking spaces will be incorporated along the Fort Dearborn access road north of 31st Street, serving 31st Street beach. A new surface lot west of Lake Shore Drive and immediately south of 31st Street will be constructed with a capacity of over 150 spaces.

The existing attractions of Burnham Park near 31st Street will remain, including 31st Street Beach, the beach house, and the Burnham Skate Park.

Parking options:

  • 31st Street Harbor Parking Garage (310 covered spaces)
  • Surface Lot on Fort Dearborn north of 31st Street (202 spaces)
  • Surface Lot off Moe Drive south of 31st Street (161 spaces)
  • Total: 573 spaces

[Currently this beach has 188 auto parking spaces, a difference of 355% compared to the proposed quantity. It currently has about 14 bike parking spaces and needs more but I cannot find evidence that this number will increase when the new harbor opens.]
