Speed Camera Violations Speed Camera Violations Transportation
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.

Parking Permit Zones Parking Permit Zones Transportation
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.
