Performance Metrics - Transportation - Snow - Uncleared Sidewalk
data.cityofchicago.org | Last Updated 2019-04-05T10:11:57.000ZWhen moisture seeps into pavement, it expands when it freezes and contracts when it thaws. This flexing of the pavement, combined with the melted water and the stress of vehicular traffic, causes pavement to deteriorate and potholes to form. The Department of Transportation (CDOT) responds to potholes reported through 311’s Customer Service Requests (CSR) system by mapping open pothole requests each morning and routing crews in geographic clusters so as to fill as many potholes as possible per day. This metric tracks the average number of days CDOT takes to complete pothole repairs per week. Total number of requests fulfilled per week is also available by mousing over columns. The target response time for pothole repairs is within 7 days. For more information about pothole repairs, see CDOT’s pothole Frequently Asked Questions page: http://www.cityofchicago.org/content/dam/city/depts/cdot/PotholeFAQ_winter1011.pdf

Strategic Subject List - Historical
data.cityofchicago.org | Last Updated 2020-09-25T21:57:26.000ZThe program described below ended in 2019. This dataset is being retained for historical reference. The information displayed represents a de-identified listing of arrest data from August 1, 2012 to July 31, 2016, that was used by the Chicago Police Department’s Strategic Subject Algorithm, created by the Illinois Institute of Technology and funded through a Department of Justice Bureau of Justice Assistance grant, to create a risk assessment score known as the Strategic Subject List or “SSL.” These scores reflect an individual’s probability of being involved in a shooting incident either as a victim or an offender. Scores are calculated and placed on a scale ranging from 0 (extremely low risk) to 500 (extremely high risk). Based on this time frame’s version of the Strategic Subject Algorithm, individuals with criminal records are ranked using eight attributes, not including race or sex. These attributes are: number of times being the victim of a shooting incident, age during the latest arrest, number of times being the victim of aggravated battery or assault, number of prior arrests for violent offenses, gang affiliation, number of prior narcotic arrests, trend in recent criminal activity and number of prior unlawful use of weapon arrests. Please note that this data set includes fields that are not used to calculate SSL, for example, neither race nor sex are used in the Strategic Subject Algorithm. Portions of the arrest data are de-identified on the basis of privacy concerns. The attributes used in the Strategic Subject Algorithm were revised on an ongoing basis during the lifetime of the program.

Taxi Trips - 2016
data.cityofchicago.org | Last Updated 2024-02-07T20:40:12.000ZTaxi trips reported to the City of Chicago in its role as a regulatory agency. 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, and times are rounded to the nearest 15 minutes. 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. See http://dev.cityofchicago.org/open%20data/data%20portal/2019/04/12/tnp-taxi-privacy.html for further discussion of the approach to privacy in this dataset.

Arrests
data.cityofchicago.org | Last Updated 2024-08-06T11:36:45.000ZEach record in this dataset shows information about an arrest executed by the Chicago Police Department (CPD). Source data comes from the CPD Automated Arrest application. This electronic application is part of the CPD CLEAR (Citizen Law Enforcement Analysis and Reporting) system, and is used to process arrests Department-wide. A more-detailed version of this dataset is available to media by request. To make a request, please email <a href="mailto:dataportal@cityofchicago.org?subject=Arrests Access Request">dataportal@cityofchicago.org</a> with the subject line: <b>Arrests Access Request</b>. Access will require an account on this site, which you may create at https://data.cityofchicago.org/signup. New data fields may be added to this public dataset in the future. Requests for individual arrest reports or any other related data other than access to the more-detailed dataset should be directed to <a href="https://home.chicagopolice.org/services/adult-arrest-search/">CPD</a>, through contact information on that site or a <a href="http://www.chicago.gov/foia">Freedom of Information Act (FOIA)</a> request. The data is limited to adult arrests, defined as any arrest where the arrestee was 18 years of age or older on the date of arrest. The data excludes arrest records expunged by CPD pursuant to the Illinois Criminal Identification Act (20 ILCS 2630/5.2). Department members use charges that appear in Illinois Compiled Statutes or Municipal Code of Chicago. Arrestees may be charged with multiple offenses from these sources. Each record in the dataset includes up to four charges, ordered by severity and with CHARGE1 as the most severe charge. Severity is defined based on charge class and charge type, criteria that are routinely used by Illinois court systems to determine penalties for conviction. In case of a tie, charges are presented in the order that the arresting officer listed the charges on the arrest report. By policy, Department members are provided general instructions to emphasize seriousness of the offense when ordering charges on an arrest report. Each record has an additional set of columns where a charge characteristic (statute, description, type, or class) for all four charges, or fewer if there were not four charges, is concatenated with the | character. These columns can be used with the Filter function's "Contains" operator to find all records where a value appears, without having to search four separate columns. Users interested in learning more about CPD arrest processes can review current directives, using the CPD Automated Directives system (http://directives.chicagopolice.org/directives/). Relevant directives include: • Special Order S06-01-11 – CLEAR Automated Arrest System: describes the application used by Department members to enter arrest data. • Special Order S06-01-04 – Arrestee Identification Process: describes processes related to obtaining and using CB numbers. • Special Order S09-03-04 – Assignment and Processing of Records Division Numbers: describes processes related to obtaining and using RD numbers. • Special Order 06-01 – Processing Persons Under Department Control: describes required tasks associated with arrestee processing, include the requirement that Department members order charges based on severity.
