Chicago Traffic and Road Conditions


Chicago Traffic Map

No Traffic Flow? Zoom in Closer or Refresh
Traffic flow lines: Black lines = a "Closed" road, Red lines = Heavy traffic flow, Yellow/Orange lines = Medium flow and Green = normal traffic. No traffic flow lines could indicate a closed road, but in most cases it means that either there is not enough vehicle flow to register or traffic isn't monitored. Also, If you do not see traffic flow, you can zoom in closer to reveal localized data. If you are unable to pan the map, press here and try again.

Traffic Incidents (beta): Each dot represents a traffic event or incident such as road construction, closure or accident. At closer zoom levels, those dots can be pressed to see more info.
