Chicago

List of all Chicago streets with suffixes and minimum and maximum address numbers.

As described in http://bit.ly/cdotpermitspost, the function of this dataset was replaced by https://data.cityofchicago.org/d/pubx-yq2d on 12/7/2015. This dataset is historical-only.

The Chicago Department of Transportation (CDOT) reviews applications for permits for the temporary use of the public way for construction projects, parades, festivals, block parties, athletic events, etc.This dataset includes permits applied for, issued, amended and expired with permit start dates beginning January 1, 2011. Note a permit may be amended if any details are changed after the initial issuance. For more information about Public Right-of-Way Use Permits, go to http://bit.ly/15ypkkL.

This dataset displays location for vehicles that have been towed and impounded by the City of Chicago within the last 90 days. Illegally parked vehicles, abandoned vehicles and vehicles used for illegal activities may be towed by the Chicago Police Department, the Department of Streets and Sanitation, the Department of Revenue, Aviation and the office of the City Clerk. After a tow request is issued, an inventory number is assigned by the Department of Streets and Sanitation and a truck is dispatched to tow the requested vehicle to a City auto pound. Disclaimer: This dataset includes vehicles towed or relocated by the City of Chicago; it does not include vehicles towed by a private towing company.

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.

This dataset shows CTA Bus Stop shelters which are slated to have digital signs added to them to show upcoming arrivals. The listing is subject to change.

This lists datasets published by CTA in the City of Chicago Data Portal.

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.

This dataset presents current and former locations of vehicles that have been relocated by the City of Chicago within the last 90 days. Vehicles may be relocated, but not impounded, due to inoperability, accident, severe weather, special events, construction or other work being performed in a thoroughfare where the vehicle was previously located.
Data Owner: Streets & Sanitation.

Average Daily Traffic (ADT) counts are analogous to a census count of vehicles on city streets. These counts provide a close approximation to the actual number of vehicles passing through a given location on an average weekday. Since it is not possible to count every vehicle on every city street, sample counts are taken along larger streets to get an estimate of traffic on half-mile or one-mile street segments. ADT counts are used by city planners, transportation engineers, real-estate developers, marketers and many others for myriad planning and operational purposes.
Data Owner: Transportation.
Time Period: 2006.
Frequency: A citywide count is taken approximately every 10 years. A limited number of traffic counts will be taken and added to the list periodically.
Related Applications: Traffic Information Interactive Map (http://webapps.cityofchicago.org/traffic/).

NOTE: This dataset has been replaced by https://data.cityofchicago.org/d/pubx-yq2d and will be removed soon. -- Current permitted street closures in Chicago by location, date and type. Closures due to construction or other work being performed in the thoroughfare are indicated by the “Street Full Closure” permit type. Street closure permits are also granted for festivals, athletic events, block parties, parades, and movie or other filming.
Data Owner: Transportation.
Time Period: All closure permits for current day.
Frequency: Data is updated daily.

This dataset contains all those street segments (individually uniquely identified by Record ID) that have been designated as belonging to a “Residential Parking Zone.” Residential Parking Zones are established by passage of legislation through the Chicago City Council; this data set is updated daily, but major update installments typically occur shortly after City Council Meetings (where/when legislation affecting zones – such as zone creation or zone modification – occurs). (See City Council Meeting schedule: https://chicago.legistar.com/Calendar.aspx.) The collection of street segments for a single zone (collectively identified by Zone number) are not required to constitute a seamless polygon; however, they must be contiguous; in this sense, “Zones” often closer resemble a collection of intersecting segments rather than an unbroken area. Segments are commonly categorized as being either “Standard” or “Buffer”: Standard means that signs exist on the street segment beginning at the low-point and ending at the high-point; Buffer means that physical signs do not exist for that zone on that physical street, but residents of addresses within that segment shall have the privilege to purchase zone products (daily permits and annual passes) for that zone, as if physical signs were installed. (In this way, segments designated as ‘Buffer’ can in fact overlap with either other buffers and/or standard segments.) Physical signs will display the zone number and the day/times when the zone restriction is in effect, e.g., “All Times” / “Anytime”; “Monday through Friday”; “6am – 6pm All Days.” During restricted days/times, any vehicle parked in the zone which does not display a valid unexpired zone product (either a daily permit or an annual pass printed on the City Vehicle Sticker) is subject to ticketing/enforcement.

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.

This list shows daily totals of ridership, by station entry, for each 'L' station dating back to 2001. Dataset shows entries at all turnstiles, combined, for each station. Daytypes are as follows: W=Weekday, A=Saturday, U=Sunday/Holiday. See attached readme file for information on how these numbers are calculated.

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.

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 contains the historical estimated congestion for the 29 traffic regions. 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/103beCf.

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.
