Monitor traffic & lane closures with QuickMap

Access real-time traffic information on the Caltrans website. The California QuickMap web page presents several types of real-time traffic information layered on a Google Map. The information includes traffic speed, lane closures and road closures due to construction and maintenance activities, incident reports, Changeable Message Sign content, camera snapshots, and active chain control requirements. Traffic speed is indicated by color-coded lines overlaying the roadway. The location of information content for the remaining layers is identified by markers (icon images) on the map. Clicking on a marker displays the information details in an info window pop-up. Click here for the mobile version: Caltrans Mobile Quickmap.

The traffic speed data information is provided by using the Google Maps Traffic Layer. This enables California QuickMap to provide speed data beyond what is available using just Caltrans data. Google uses Caltrans data as well as other sources of data, like Automated Vehicle Location (AVL) from private companies, as well as cellular phone data. The colors represent speeds with the following definitions:

  • Green: more than 50 miles per hour or 80 kilometers per hour
  • Yellow: 25 – 50 miles per hour or 40 – 80 kilometers per hour
  • Red: less than 25 miles per hour or 40 kilometers per hour
  • Red/Black: very slow, stop-and-go traffic
  • Gray: no data currently available
