Current chicago traffic map1/23/2024 In some instances, due to the inability the registered owner of the offending vehicle, the violation may not be issued as a citation. The reported violations are those that have been collected by the camera and radar system and reviewed by two separate City contractors. The most recent 14 days are not shown due to revised data being submitted to the City of Chicago. 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 data reflects violations that occurred from Juntil present, minus the most recent 14 days. This dataset reflects the daily volume of violations that have occurred in Children's Safety Zones for each camera. Current estimates of traffic congestion by region are available at. The segment speed and traffic region congestion estimates together may give a better understanding of the actual traffic conditions. Speed on individual arterial segments can fluctuate from heavily congested to no congestion and back in a few minutes. 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. Most volatility in arterial speed comes from the very nature of the arterials themselves. However, the congestion estimates for the traffic regions remain consistent for a relatively longer period. There is much volatility in traffic segment speed. ![]() 29 regions are created to cover the entire city (except O’Hare airport area). A traffic region is comprised of two or three community areas with comparable traffic patterns. ![]() Congestion by Traffic Region gives the average traffic condition for all arterial street segments within a region. Traffic Segment level congestion is available for about 300 miles of principal arterials. Congestion estimates by traffic segments gives observed speed typically for one-half mile of a street in one direction of traffic. Two types of congestion estimates are produced every 10 minutes: 1) by Traffic Segments and 2) by Traffic Regions or Zones. 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. Together may give a better understanding of the actual traffic conditions. The segment speed and traffic region congestion estimates speed on individual arterial segments can fluctuate from heavily congested to no congestion and back in a few minutes. Intersections, traffic signals, transit movements, availability of alternative routes, crashes, short length of the segments, etc. ![]() Due to a myriad of factors, including but not limited to frequent However, the congestion estimates for the traffic regions remain consistent for relatively longer period. This dataset contains the current estimated speed for about 1250 segments covering 300 miles of arterial roads. ![]()
