The Chicago region traffic congestion scans were created by averaging five minute speed data obtained from freeway loop detectors, radar detectors, 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.
