IE511 is a comprehensive traveler information system that fosters a multimodal approach to mobility in Southern California. The service is available online at IE511.org, through a custom smart phone App for both iPhone and Android, and by telephone by dialing 511 from within the Inland Empire and 1-877-MYIE511 from anywhere.

IE511.org helps drivers avoid traffic congestion with quality Real-time Traffic information that includes travel times, incidents, sig alerts, and chain controls. The Bus/Rail Trip Planner, powered by Google transit, allows users to choose to avoid traffic and plan a trip that includes both bus and rail service. It also provides links to bus services throughout Southern California and Specialized Transit services within the Inland Empire. Rideshare information includes maps of carpool lanes throughout Southern California, locations and features of Park and Ride lots, and serves as the portal for RCTC’s Commuter Assistance Programs for both commuters and employers.

Users can also sign up for Twitter feeds of major road closures and get traffic-inducing planned construction information through Facebook.

By providing commuters with timely travel information and commute options, the IE511 system benefits the region with improved highway efficiency and air quality.
