This dataset contains the historical estimated congestion for the 29 traffic regions, from January 2013 to May 2018. Newer records are in https://data.cityofchicago.org/d/sxs8-h27x. The most recent estimates for each region are in https://data.cityofchicago.org/d/t2qc-9pjd.

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.

Warming Centers offer residents warming refuge from oppressive winter cold. The Chicago Department of Family and Support Services operates six Warming
Centers during the winter months. Additional facilities are opened as needed in libraries, Park District buildings, senior centers and other community venues.
You may call 311 to locate a Warming Center in your area, or go to http://bit.ly/kIhHPj for more information.

This dataset is historical-only. -- Results from a 2017-2018 project of City-installed sensors measuring water runoff from streets and sidewalks. These data can be used to measure the impact of sustainable green infrastructure on flooding. These sensors also captured weather data.

Each row corresponds to a sensor measurement at a specific time and location. Each row is a different sensor, which can be determined from the "Measurement Title" column. The value for each measurement is always numeric and available in the "Measurement Value" column. The corresponding unit of measurement is in the "Units" column. Data may be missing at times due to sensors not being available.

The Chicago Building Energy Use Benchmarking Ordinance calls on existing municipal, commercial, and residential buildings larger than 50,000 square feet to track whole-building energy use, report to the City annually, and verify data accuracy every three years. The law, which phases in from 2014-2017, covers less than 1% of Chicago’s buildings, which account for approximately 20% of total energy used by all buildings. For more details, including ordinance text, rules and regulations, and timing, please visit www.CityofChicago.org/EnergyBenchmarking

The ordinance authorizes the City to share property-specific information with the public, beginning with the second year in which a building is required to comply.

NeighborSpace is a nonprofit organization whose mission is to acquire and support the community based management of small parks, gardens, natural areas, river edges, and scenic landscapes in the City of Chicago for preservation, conservation, and educational public open space purposes.

NeighborSpace primarily focuses on those parcels where community groups have established gardens or parks. These groups apply to NeighborSpace so the site can be owned by a nonprofit that has a mission to preserve and protect the sites. NeighborSpace continues to work in partnership with the three founding governmental agencies the City of Chicago, Chicago Park District, the Forest Preserve District of Cook County, as well as other nonprofit organizations and local community groups.

This dataset and corresponding map provide the location, satellite images and square footage of existing green roofs within the City of Chicago. This information is derived from an analysis of high-spatial resolution (50cm), pan-sharpened, ortho-rectified, 8-band multi-spectral satellite images collected by Digital Globe’s Worldview-2 satellite. The City supplied the consultant with a 2009 City boundary shapefile to determine the required extent of the imagery. Acquisition of three different strips of imagery corresponding to the satellite’s paths was required. These strips of imagery spanned three consecutive months and were collected in August 2010 (90% coverage), September 2010 (5% coverage) and October 2010 (5% coverage). The results of the analysis include overall count of vegetated roofs, their total square footage, and the ratio of required to elective vegetated roofs. A total of 359 vegetated roofs were identified within the City of Chicago. The total square footage of these vegetated roofs was calculated to be approximately 5,469,463 square feet. The ratio of required vegetated roofs to elective vegetative roofs was 297:62 (~5:1). The median size of the vegetated roofs was calculated to be 5,234 square feet.
