No Traffic Flow? Zoom in Closer or Refresh

How to use the Santa Clara Traffic Map

Traffic flow lines: Red lines = Heavy traffic flow, Yellow/Orange lines = Medium flow and Green = normal traffic. Black lines or 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 (to focus off of the map) 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. Once a layer of traffic info has popped-up, be sure to press/click any additional arrows (e.g. 1 of 3) in the top right above the title to see other the details of the impact.

Impact Legend: Traffic and Road Incident Icon - Critical Impact Critical Traffic and Road Incident Icon - Major Impact Major Traffic and Road Incident Icon - Minor Impact Minor Traffic and Road Incident Icon - Low Impact Low
