The Chicago region traffic congestion scans were created by averaging five minute speed data obtained from freeway loop detectors, radar, and mobile technology data. The traffic scans display average speed on a freeway corridor as a function of time of day (the x-axis) and location (the y-axis) along a freeway corridor.

About the Data
2016 scans were prepared using the RITIS system, developed by the University of Maryland's CATT Lab. Data comes from the National Performance Measure Research Dataset (NPMRDS), a HERE dataset made available to states and MPOs through the Freight Management and Operations Program of the Federal Highway Administration.
Notice: 2016 congestion scans are based upon work supported by the Federal Highway Administration under contract number DTFH-13-C-00012. Any opinions, findings, and conclusions or recommendations expressed in this publication are those of the author(s) and do not reflect the views of the Federal Highway Administration.
