The real-time traffic datasets are not updating, due to a technical problem. These datasets are:
- Chicago Traffic Tracker - Congestion Estimates by Segments
- Chicago Traffic Tracker - Congestion Estimates by Regions
The historical datasets that accumulate records over time may or may not end up missing the records for the time period of this outage. We are not sure yet.
We are investigating the problem and will update this post with any significant updates.
Update 4/16/2018, 3:00 pm: The problem has been resolved and real-time records are now being posted. Most historical records between 4/14/2018, 8 pm and 4/16/2018, 1 pm will not appear in the historical datasets.
