511 San Diego

The 511 San Diego mobile app provides real-time access to traveler information.

The 511 San Diego mobile application provides real-time access to traveler information supplied by Caltrans, MTS, and NCTD in partnership with the San Diego Association of Governments (SANDAG). Maps depict current traffic conditions and the latest incident and construction information on all interstates and state routes in the San Diego region. Enhanced information is available for the I-15 corridor, including real-time dynamic toll rates for the I-15 Express Lanes, predictive travel times, suggested alternative routes, congestion information, and special event information provided by Caltrans. Maps show locations of roadside cameras and allow users to view current camera images; maps also display MTS bus routes, fares, and arrival times. As the user moves through the roadway network, the map tracks the user’s location and provides optional text-to-speech and look-ahead speech commands for hands-free use while driving. Additional 511-related information is accessible through the application’s “more” menu, including links to the @SANDAG Twitter feed and webpages for local 511-related services.
