Chicago crash data updated to show monetary damages based on a person’s situation in the crash

February 27, 2026 / / 0 Comments

The Chicago Crashes page that is hosted on Chicago Cityscape shows weekly and year-to-date crash statistics along with estimated costs of those crashes, broken down by person type. Today I published a major change to present the stats better, in a way that matches the costs of the crash that are said to be different based on the person’s situation – whether they were a pedestrian, bicyclists, or motor vehicle occupant – in the crash. Prior to this change, every person in the crash was assigned the same monetary cost as “driver” even if they were a pedestrian or bicyclist.

Improved cost tables

The “Costs of these crashes” tables have two improvements.

  • Each injury-severity column now shows a count alongside the dollar figure, so you can see exactly how many people of each type were killed, had incapacitating injuries, or had non-incapacitating injuries for the selected time period. This makes it easier to verify the numbers and understand the scale behind the cost estimates.
  • The tables previously listed three person-type rows: Driver/Passenger, Pedestrian, and Bicycle. The CPD dataset actually includes six person types. The two remaining types — non-motor vehicle occupants and non-contact vehicle occupants — were being silently folded into the Driver/Passenger row. They now appear in their own “Other” row.

What’s interesting is the differences in value. Pedestrian is “worth” less than bicyclist. Cost estimates use values from the CDC’s WISQARS Cost of Injury study and vary by injury severity and person type.

  • A pedestrian who is killed is said to result in $14,169 in medical costs and $10,500,000 in non-medical costs, totaling $10,514,169
  • A bicyclist who is killed is said to result in $19,750 in medical costs and $10,800,000 in non-medical costs, totaling $10,819,750
  • A motor vehicle occupant who is killed is said to result in $11,556 in medical costs and $10,600,000 in non-medical costs, totaling $10,611,556

I haven’t figured out why the pedestrian has a lower non-medical cost.

A note on count differences

You may notice that the injury counts in the “Costs of these crashes” table differ slightly from the totals in the “killed or injured” summary above it. This is expected and I will try to reconcile them 1:1 soon. The two figures come from two Chicago Police Department datasets and may be modified at certain times in ways that my import system does not catch. They differ by a small number of records at any given time.

Crash data is sourced from the Traffic Crashes — Crashes and Traffic Crashes — People datasets on the Chicago Data Portal.

Illinois legislature adopts People Over Parking Act to ban parking mandates in transit-served areas

October 31, 2025 / / 0 Comments

This article has been re-published and expanded on Streetsblog Chicago. Please read that version.

At about 4:22 AM this morning the Illinois Senate concurred with the Illinois House on bill SB2111 (PDF), approving a revenues and reform package that will close budget gaps and provide additional funding for the state’s 63 transit agencies. Among the reforms are establishing a new oversight authority that will centralize service planning and fare-setting in Chicagoland and assigning powers to build transit-supportive development, among other major and unique policy changes.

Development around the Naperville Metra station cannot be mandated to provide car parking after SB2111 goes into effect.

Additionally, the bill includes the People Over Parking Act, which was introduced by Rep. Buckner earlier this year and prohibits municipalities from requiring car parking for residential and commercial uses in areas served by transit. The bill, which will go into effect on June 1, 2026 (per House Amendment 4), will also apply in home rule communities. This includes Chicago, which passed its own transit-adjacent parking reform that took effect on September 25, 2025.

Specifically, the ban on parking mandates applies when the following is true:

  • a development project is for new construction or renovation and that is not a hotel, motel, bed and breakfast, or other transient lodging
  • the project is located within one-half mile of a public transportation hub (nodes) or one-eighth mile of a public transportation corridor (street segments)

A public transportation hub is a node that includes rail transit stations, a boat or ferry terminal that is served by a bus stop or a rail transit station, and street intersections where two or more bus routes meet and those bus routes have a combined frequency of 15 minutes or less during the morning and afternoon peak commute periods. This means that new housing will soon be able to be developed, at lower cost, within a half mile of the Highland Park Metra station without any parking.

Metra has 168 stations outside of Chicago, and there are also Metrolink rail stations in Illinois communities east of St. Louis, Missouri. That’s in addition to higher-frequency bus service in Champaign and some communities served by Pace bus.

A public transportation corridor is a street segment that has one or more bus routes that have a combined frequency of 15 minutes or less during the morning and afternoon peak commute periods.

The fine print

Municipalities are still allowed to enact minimum parking requirements for bicycles; and they can establish maximum parking allowances. The act does not apply to existing approved Planned (Unit) Developments but will apply to any amendments or extensions if the amendment or extension will increase the car parking requirement.

In situations where developments are voluntarily providing car parking, municipalities can impose requirements that reserve space for car share vehicles, that some parking be made available to the public, and that parking must be made available for a charge. Municipalities cannot require that parking be made available for free.

I believe that this new law will override Chicago’s requirement that projects in the Downtown zoning districts and projects in transit-serve areas that are served only by Metra obtain an administrative adjustment to build less parking that otherwise required.

Finally, Illinois has existing code regarding electric vehicle charging and sets a standard for how much of the provided parking must be “EV ready”, “EV capable”, and “EV installed” (read the Illinois Electric Vehicle Charging Act) – those requirements are not impacted by the People Over Parking Act.

Chicago Fire share the stadium plan they plan to share with the Plan Commission

August 22, 2025 / / 0 Comments

Updated September 10 to add this link to the traffic and transportation study, and the town hall video hosted by 3rd Ward Alderperson Pat Dowell.

The Chicago Fire owner, Joe Mansueto, plans to build a soccer stadium on “The 78”, a vacant property in the South Loop. The 78 is a planned development that was approved about six years ago to have office towers and about 10,000 homes in multiple buildings. Since the stadium will significantly alter the approved plan, Related Midwest, the owner of The 78, needs to present the revision to Chicago Plan Commission and gain their approval before also gaining approval from the City Council’s zoning committee and City Council.

Rendering of the stadium, looking north-northeast. Other renderings from the set show the area between the stadium and the riverwalk eventually being redeveloped into buildings and differently-designed outdoor spaces.

Here’s what’s changed

We can see what Mansueto and RM are proposing because they submitted their zoning change application to revise the PD back in July, which was subsequently posted in the City Clerk’s online legislation database. (A zoning change application and a Planned Development amendment are amendments to city law; refer to the approved plan in this PD 1434 document.)

  • The soccer stadium would be located approximately between 13th and 14th Streets. The rights of way for these two streets would be delineated and “dedicated” to the public.
  • Metra tracks would remain where they are. At the north edge of the site they enter the site about 185′ west of Clark Street, and then gradually shift to the east to hug Clark Street. The original plan would realign the tracks so that new streets could intersect Clark Street.
  • For the planners, the PD subareas’ boundaries are reconfigured.
  • Crescent Park is out of the plan. This central park would follow the historical Chicago River alignment, before it was straightened from Polk Street to 18th Street in 1926.
  • The riverwalk would be narrowed to 40′ from the currently approved plan for a 75′ wide riverwalk and 25′ “riverfront amenity zone” adjacent to buildings. (City law requires riverwalks to be a minimum of 30′ wide.)
Proposed open space plan

The stadium would have these pedestrian and bicycle access points:

  1. Wells Street, south from Polk Street
  2. Wentworth Avenue, north from 18th Street
  3. A newly built LaSalle Street, south from the elevated Roosevelt Road. This is also where transit riders from the Roosevelt ‘L’ station or any of the buses that use Roosevelt or Clark would access the site.

There would not be access from Clark Street and points east; some of the Dearborn Park and Burnham Station residents may prefer this, given how some of them reacted when a new CTA Red Line station was proposed at the existing substation on the east side of Clark Street at 15th Street. RM eventually moved the proposal to be within The 78.

The proposed site plan also shows a publicly owned parking structure in phase one, below the Roosevelt Road elevation.

What’s next

Expect another 3rd Ward town hall, in September before the next Plan Commission meeting on September 18. The Plan Commission agenda hasn’t been set so it’s not confirmed that the development team will present on September 18.

The plan can also change again, between now and the Plan Commission meeting. What’s presented at Plan Commission will be what is presented to City Council.

Transit in St. Petersburg

February 4, 2025 / / 0 Comments

Steven’s note: I originally drafted this post in December 2016, for Transitland (my contract employer at the time). Here’s the original (archived) post on Transitland’s website.

St. Petersburg Tramway Russia 2013

We [TransitLand] recently added the feed for surface transit in Saint Petersburg, Russia. ORGP is the transport organizer’s name in the Latin alphabet. ORGP website is a central source of information for the various municipally- and privately-operated ferry, bus, and tram routes.

St. Petersburg (SPb) also has trolley bus routes, which drive using electricity they collect from an overhead wire. These buses can only deviate from their route where an intersection between wires is available.

There are 1,066 routes in the SPb feed.

  • 5 ferry routes
  • 48 tram routes
  • 51 trolley bus routes
  • Remaining are bus routes using conventional buses.

I couldn’t find ridership information for these routes, but the statistics on the Wikipedia article say that a much higher proportion of SPb residents ride the subway each weekday than people in Chicago ride the ‘L’  in my hometown. The ‘L’ runs mostly on elevated track, but has some subway and at-grade sections.

Speaking of the subway in SPb, we don’t have their GTFS feed yet and we could use your help. If you know the URL to the SPb’s subway feed, submit it on this form.

The Transitland connection

One of the features in Mapzen’s new Mobility Explorer, launched in late November, is to drill down into the transit routes, stops, and operators in a city – all of that data is based on what’s available in Transitland. It visualizes this data quickly and easily; think of it as an expansion of what Transitland’s Playground does.

Once you’re in Mobility Explorer, search for “Saint Petersburg, Russia” and click on the result. On the left sidebar, click on “show routes” and you’ll see that all of the routes in SPb will appear in the same color.

Click “style by: mode” to distinguish the subway, ferry, bus, and trolley bus routes in different colors.

A great feature of Mobility Explorer is that it tells you the Transitland API call to get the data in the current map view. You’ll find this link under the main “Show [xyz]” buttons in the left sidebar.

It’s very common see regular length buses with three doors in Europe, while buses in North America often have two doors. Articulated buses often have 3-4 doors, 1-2 more than their counterparts in the United States.

Lake Calumet had a lot more water surface area 50 years ago

November 9, 2024 / / 0 Comments

I visited Big Marsh Bike Park with a friend three weekends ago to ride mountain bikes on the single track, check out the park’s campsite, see if people were still drag racing on Stony Island Avenue (they were), and finally, try to get a sense of where the access trail from Pullman in the west will cross over Lake Calumet by viewing the “land bridge” from the air.

According to the “preferred alignment” map below, the future bike trail will cross the lake at the shortest opening where the spit is on the left. The photo is facing due west.

While researching the proposed multi-use trail, boardwalk, and bridge, I decided to look up historic aerial photos to try and understand when and where the land around the lake was filled in. (I think the Illinois International Port District is the proposer.)

Renderings and map by Epstein.

The Lake Calumet diptych I made shows two aerial photos – taken from airplanes – of Lake Calumet in 1970 and 1995. The images come from the Chicago Metropolitan Agency for Planning’s collection of three decades of 6,300 aerial photos across the six country region.

In the 1995 image you can see the Harborside International Golf Center built on landfill (also in 1995), additional slips for ships, and other land and water feature additions and subtractions.

The two photographs were taken slightly offset from each other but I scaled and adjusted their alignments to match each other as best as I could.
