Average Daily Traffic Counts Average Daily Traffic Counts Transportation
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/).

Chicago Police Department - Illinois Uniform Crime Reporting (IUCR) Codes Chicago Police Department - Illinois Uniform Crime Reporting (IUCR) Codes Public Safety
Illinois Uniform Crime Reporting (IUCR) codes are four digit codes that law enforcement agencies use to classify criminal incidents when taking individual reports. These codes are also used to aggregate types of cases for statistical purposes. In Illinois, the Illinois State Police establish IUCR codes, but the agencies can add codes to suit their individual needs. The Chicago Police Department currently uses more than 350 IUCR codes to classify criminal offenses, divided into “Index” and “Non-Index” offenses. Index offenses are the offenses that are collected nation-wide by the Federal Bureaus of Investigation’s Uniform Crime Reports program to document crime trends over time (data released semi-annually), and include murder, criminal sexual assault, robbery, aggravated assault & battery, burglary, theft, motor vehicle theft, and arson. Non-index offenses are all other types of criminal incidents, including vandalism, weapons violations, public peace violations, etc.

Life Safety Evaluations Life Safety Evaluations Buildings
This dataset is a listing of the report status of all residential buildings required to submit a Life Safety Evaluation under city ordinance.

This dataset does not describe the overall safety of a building, only whether or not the life safety evaluation was submitted and approved by the City of Chicago. Please note that the majority of reports “failed” initially as a result of a new reporting process and changes to building standards. For more information on the City’s life safety ordinance, visit http://bit.ly/ygORcq. Data Owner: Buildings. Frequency: Data is updated monthly.
