511 San Diego Mobile Application

App Store     Google Play

Traffic information now fits in the palm of your hand with the 511 San Diego mobile application available for iOS and Android. The app provides real-time access to traveler information supplied by Caltrans, MTS, and the cities of San Diego, Escondido, and Poway, in partnership with the San Diego Association of Governments (SANDAG).

The 511 San Diego app features:

  • Maps with current traffic conditions and the latest incident and construction information on all interstates and state routes in the San Diego region
  • Real-time dynamic toll rates for the I-15 Express Lanes
  • Predictive travel times, congestion information, and special event information for the I-15 corridor
  • Real-time MTS information, including arrival times
  • Access to MTS and NCTD bus routes and fares
  • Customizable freeway incident notifications for your commute
  • Ability to view current roadside camera images
  • Links to other resources to improve your commute

As you drive through the roadway network, the map shows your location and provides optional text-to-speech and look-ahead speech commands for hands-free use while driving.

The 511 San Diego app is the most recent innovation to come from the multimodal I-15 Integrated Corridor Management (ICM) project. San Diego was chosen as one of two pilot sites in the nation to develop, implement, and operate and ICM system to improve I-15 corridor travel times and reliability.
