Dataset
Bike racks in Chicago.
This dataset contains bike racks installed between 2015-2021. There is another dataset from 2011 at https://data.cityofchicago.org/d/cbyb-69xx that shows bike racks in existence at that time. We hope eventually to consolidate the data into this dataset.
This dataset is in a format for spatial datasets that is inherently tabular but allows for a map as a derived view. Please click the indicated link below for such a map.
To export the data in either tabular or geographic format, please use the Export button on this dataset.
To attempt to make historical versions of this dataset more available, "Dataset Changelog" is enabled at the bottom of the main page. We cannot guarantee that the archival records will remain permanently so advise downloading any you think you may want. Some intermediate versions, especially minor changes, may not be visible. The map based on this dataset will not have past versions.

Data Lens
Taxi trips reported to the City of Chicago in its role as a regulatory agency. For the full data, see the bottom of this page or https://data.cityofchicago.org/d/wrvz-psew.
To protect privacy but allow for aggregate analyses:
- The Taxi ID is consistent for any given taxi medallion number but does not show the number.
- Census Tracts are suppressed in some cases.
- Times are rounded to the nearest 15 minutes.
Trip Total, which is used on some cards below, is the total paid, although cash tips do not appear in either that column or the Tips column.
Due to the data reporting process, not all trips are reported but the City believes that most are.
See http://digital.cityofchicago.org/index.php/chicago-taxi-data-released for more information about this dataset and how it was created.

This dataset contains information about vehicles (or units as they are identified in crash reports) involved in a traffic crash. This dataset should be used in conjunction with the traffic Crash and People dataset available in the portal. “Vehicle” information includes motor vehicle and non-motor vehicle modes of transportation, such as bicycles and pedestrians. Each mode of transportation involved in a crash is a “unit” and get one entry here. Each vehicle, each pedestrian, each motorcyclist, and each bicyclist is considered an independent unit that can have a trajectory separate from the other units. However, people inside a vehicle including the driver do not have a trajectory separate from the vehicle in which they are travelling and hence only the vehicle they are travelling in get any entry here. This type of identification of “units” is needed to determine how each movement affected the crash. Data for occupants who do not make up an independent unit, typically drivers and passengers, are available in the People table. Many of the fields are coded to denote the type and location of damage on the vehicle. Vehicle information can be linked back to Crash data using the “RD NO” field. Since this dataset is a combination of vehicles, pedestrians, and pedal cyclists not all columns are applicable to each record. Look at the Unity Type field to determine what additional data may be available for that record.

Crash data shows information about each traffic crash on city streets within the City of Chicago limits and under the jurisdiction of Chicago Police Department (CPD). Data are shown as is from the electronic crash reporting system (E-Crash) at CPD, excluding any personally identifiable information. Records are added to the data portal when a crash report is finalized or when amendments are made to an existing report in E-Crash. Data from E-Crash are available for some police districts in 2015, but citywide data are not available until September 2017. About half of all crash reports, mostly minor crashes, are self-reported at the police district by the driver(s) involved and the other half are recorded at the scene by the police officer responding to the crash. Many of the crash parameters, including street condition data, weather condition, and posted speed limits, are recorded by the reporting officer based on best available information at the time, but many of these may disagree with posted information or other assessments on road conditions. If any new or updated information on a crash is received, the reporting officer may amend the crash report at a later time. A traffic crash within the city limits for which CPD is not the responding police agency, typically crashes on interstate highways, freeway ramps, and on local roads along the City boundary, are excluded from this dataset.
All crashes are recorded as per the format specified in the Traffic Crash Report, SR1050, of the Illinois Department of Transportation. As per Illinois statute, only crashes with a property damage value of $1,500 or more or involving bodily injury to any person(s) and that happen on a public roadway and that involve at least one moving vehicle, except bike dooring, are considered reportable crashes. However, CPD records every reported traffic crash event, regardless of the statute of limitations, and hence any formal Chicago crash dataset released by Illinois Department of Transportation may not include all the crashes listed here.

This data contains information about people involved in a crash and if any injuries were sustained. This dataset should be used in combination with the traffic Crash and Vehicle dataset. Each record corresponds to an occupant in a vehicle listed in the Crash dataset. Some people involved in a crash may not have been an occupant in a motor vehicle, but may have been a pedestrian, bicyclist, or using another non-motor vehicle mode of transportation. Injuries reported are reported by the responding police officer. Fatalities that occur after the initial reports are typically updated in these records up to 30 days after the date of the crash. Person data can be linked with the Crash and Vehicle dataset using the “RD NO” field. A vehicle can have multiple occupants and hence have a one to many relationship between Vehicle and Person dataset. However, a pedestrian is a “unit” by itself and have a one to one relationship between the Vehicle and Person table.

All drivers reported by Transportation Network Providers (sometimes called rideshare companies) to the City of Chicago as part of the licensing process and routine reporting required by ordinance.
As of the creation of this dataset, there have been four TNPs licensed to operate in Chicago, although never more than three at any given time and currently three. Drivers reported by more than one company in the same month are combined and the MULTIPLE_TNPS column is marked as TRUE. However, the matching process is imperfect so not all such drivers are necessarily identified. Similarly, matching between the licensing and routine reporting databases is imperfect, creating potential for occasional errors.
The reporting is done on a monthly basis, as indicated in the MONTH_REPORTED column. However, starting in 2018, the reports are batched and files for all three months in a quarter are delivered to the City of Chicago at the end of each quarter. Due to an issue in this transition, some vehicle records for Q2 2018 (April-June) were reported for the quarter as a whole, rather than for individual months. For purposes of this dataset, those records have been assigned to 2018-06 (June). Therefore, some caution in interpreting this month and the quarter as a whole is advised.

This dataset reflects the daily volume of violations created by the City of Chicago Red Light Program for each camera. The data reflects violations that occurred from July 1, 2014 until present, minus the most recent 14 days. This data may change due to occasional time lags between the capturing of a potential violation and the processing and determination of a violation. The most recent 14 days are not shown due to revised data being submitted to the City of Chicago during this period. The reported violations are those that have been collected by the camera system and reviewed by two separate City contractors. In some instances, due to the inability the registered owner of the offending vehicle, the violation may not be issued as a citation. However, this dataset contains all violations regardless of whether a citation was actually issued, which provides an accurate view into the Red Light Program. Because of occasional time lags between the capturing of a potential violation and the processing and determination of a violation, as well as the occasional revision of the determination of a violation, this data may change. More information on the Red Light Program can be found here: http://www.cityofchicago.org/city/en/depts/cdot/supp_info/red-light_cameraenforcement.html. The corresponding dataset for speed camera violations is https://data.cityofchicago.org/id/hhkd-xvj4.

Applications to the Chicago Department of Transportation for permits under its jurisdiction, which typically are permits to block or otherwise affect public streets in some way. Because all permits start as applications, this dataset also serves as a list of permits granted.

NOTE, 6/11/2020: We have significantly scaled back this dashboard for performance reasons. The underlying dataset has become large enough that, with the frequent data updates, the background processing to update the full dashboard was interfering with the dataset, itself. We hope this change will help, and that we may even be able to restore some cards to this dashboard eventually. We recommend using the "Visualize" option on the dataset to create charts. Some options there allow for categorization and filtering similar to these dashboards.
This dataset contains the historical estimated congestion for over 1,000 traffic segments, starting in approximately March 2018.
The Chicago Traffic Tracker estimates traffic congestion on Chicago’s arterial streets (non-freeway streets) in real-time by continuously monitoring and analyzing GPS traces received from Chicago Transit Authority (CTA) buses. Two types of congestion estimates are produced every 10 minutes: 1) by Traffic Segments and 2) by Traffic Regions or Zones. Congestion estimates by traffic segments gives observed speed typically for one-half mile of a street in one direction of traffic. Traffic Segment level congestion is available for about 300 miles of principal arterials.
Congestion by Traffic Region gives the average traffic condition for all arterial street segments within a region. A traffic region is comprised of two or three community areas with comparable traffic patterns. 29 regions are created to cover the entire city (except O’Hare airport area). There is much volatility in traffic segment speed. However, the congestion estimates for the traffic regions remain consistent for a relatively longer period. Most volatility in arterial speed comes from the very nature of the arterials themselves. Due to a myriad of factors, including but not limited to frequent intersections, traffic signals, transit movements, availability of alternative routes, crashes, short length of the segments, etc. Speed on individual arterial segments can fluctuate from heavily congested to no congestion and back in a few minutes.
The segment speed and traffic region congestion estimates together may give a better understanding of the actual traffic conditions.

This dataset reflects the daily volume of violations that have occurred in Children's Safety Zones for each camera. The data reflects violations that occurred from July 1, 2014 until present, minus the most recent 14 days. This data may change due to occasional time lags between the capturing of a potential violation and the processing and determination of a violation. The most recent 14 days are not shown due to revised data being submitted to the City of Chicago. The reported violations are those that have been collected by the camera and radar system and reviewed by two separate City contractors. In some instances, due to the inability the registered owner of the offending vehicle, the violation may not be issued as a citation. However, this dataset contains all violations regardless of whether a citation was issued, which provides an accurate view into the Automated Speed Enforcement Program violations taking place in Children's Safety Zones. More information on the Safety Zone Program can be found here: http://www.cityofchicago.org/city/en/depts/cdot/supp_info/children_s_safetyzoneporgramautomaticspeedenforcement.html. The corresponding dataset for red light camera violations is https://data.cityofchicago.org/id/spqx-js37.
