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.

Moratoriums are established by the Department of Transportation as a method of protecting reconstructed or repaved roadways within the boundaries of the city.

By having access to this Moratorium list in advance, contractors or utilities with projects that require excavation of roadways can more effectively plan and review conflicts that will be encountered. Currently, roadway sections with active moratoriums have special consideration as to method and size of restoration, and additionally, increased permit fees. Three moratorium types are displayed on this web site: (1) Street Construction is used when the street has been reconstructed. By City ordinance, the moratorium is ten (10) years and during this period permit fees are doubled. (2) Street Resurfacing is used when the road has been repaved. By City ordinance, the moratorium is seven (7) years and during this period permit fees are doubled. (3) Median or Median Landscaping is used where landscaped medians or planters exist on the street median. For these moratoriums types, there is no fee adjustment; however, if a construction permit is being requested, the applicant will be directed to review the planned project with the Department of Transportation/Division of Engineering staff for special instructions on how to properly protect or reconstruct street medians.

This dataset shows total daily ridership on a per-route basis dating back to 2001. Daytypes are as follows: W=Weekday, A=Saturday, U=Sunday/Holiday. See attached readme file for more detailed information.

Pedestrian Streets (P-Streets) are segments of street created in Chicago intended to preserve and enhance the character of streets and intersections that are widely recognized as Chicago's best examples of pedestrian-oriented shopping districts.

This lists individual Divvy bike sharing trips, including the origin, destination, and timestamps for each trip. Trips are included when there is an starting and end date. Trips using a subscriber pass will include some basic demographic data (gender and age) that is associated with the account. For more information see https://divvybikes.com/system-data.

Major streets in Chicago. To view or use these files, compression software and special GIS software, such as ESRI ArcGIS, is required.

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. See more information about CDOT permits at http://www.cityofchicago.org/city/en/depts/cdot/provdrs/construction_information/svcs/online-permit-portal.html.

This list of 'L' stops provides location and basic service availability information for each place on the CTA system where a train stops, along with formal station names and stop descriptions.

Street center lines in Chicago. The data can be viewed on the Chicago Data Portal with a web browser. However, to view or use the files outside of a web browser, you will need to use compression software and special GIS software, such as ESRI ArcGIS (shapefile) or Google Earth (KML or KMZ), is required.

A list of the stations where one can pick up and return bicycles from the Divvy bicycle sharing system (http://divvybikes.com/). This dataset contains all stations. For a list of only those stations currently in service, see https://data.cityofchicago.org/d/67g3-8ig8. For real-time status of stations in machine-readable format, see https://gbfs.divvybikes.com/gbfs/gbfs.json.

This dataset lists monthly station entry averages, by day type (Weekday, Saturday or Sunday/Holiday), as well as monthly totals, beginning in 2001. Note that some stations (such as on the Cermak Branch--now Pink Line) and Skokie did not have Saturday and/or Sunday/holiday service until more recent years, although, in cases where weekday service ran past midnight, late evening fares may appear as part of Saturday tallies.

This dataset gives annual ridership totals dating to the mid-1980s. Numbers are presented in boardings (see attached readme file for information on how these numbers are calculated).

This dataset shows approximate, average, weekday boardings by bus stop from the month of October 2012.

Records involving any degree of street closure from the underlying dataset: 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. See more information about CDOT permits at http://www.cityofchicago.org/city/en/depts/cdot/provdrs/construction_information/svcs/online-permit-portal.html.

This dataset contains the historical estimated congestion for 1270 traffic segments, in selected time periods from August 2011 to May 2018. Newer records are in https://data.cityofchicago.org/d/sxs8-h27x. The most recent estimates for each segment are in https://data.cityofchicago.org/d/n4j6-wkkf.

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. Current estimates of traffic congestion by region are available at http://bit.ly/Vz3rIh.

Due to a change in the data source, discussed at http://dev.cityofchicago.org/open%20data/data%20portal/2019/07/10/divvy-datasets-frozen.html, records between 7/7/2019 and 12/9/2019 are missing.

This dataset shows the location, first operational date, and approaches of the red light cameras in the City of Chicago. The approach describes the originating direction of travel which is monitored by a red light camera.

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. Inclusion of a driver in a monthly report indicates that the driver was eligible for trips in Chicago in that month for at least one day, regardless of whether he or she actually provided any rides. If a driver is eligible in multiple months, which is common, he or she will have records in each of these reporting months.

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.

Pedway routes in Chicago. Chicago’s downtown pedestrian way system, the Pedway, lies in the heart of the city. This system of underground tunnels and overhead bridges links more than 40 blocks in the Central Business District, covering roughly five miles.. To view or use these files outside of a web brower, compression software and special GIS software, such as ESRI ArcGIS, is required.

This dataset shows monthly averages, by day type (weekday, Saturday or Sunday/Holiday) and monthly totals for all CTA bus routes, back to 2001. See attached readme file for information on how these numbers are calculated.
