511 is managed by a partnership of public agencies led by the Metropolitan Transportation Commission, the California Highway Patrol, and the California Department of Transportation. 511 was developed with the mission to provide comprehensive, accurate, reliable and useful multimodal travel information to meet the needs of Bay Area travelers.
Traffic Partners
-
Caltrans
Caltrans is the lead agency in operating the region's freeway system. Traffic flow is monitored as part of this effort, using loop detectors embedded in the pavement, as well as off-pavement sensors. Traffic counts and speeds from these detectors are reported back to Caltrans’ District 4 Transportation Management Center (TMC) in Oakland. In addition to detector data, the TMC also uses closed circuit television cameras (CCTVs) to check hot spots on the freeway. The 511 Operations Center is co-located with the TMC within the Caltrans facility, allowing Caltrans' TMC staff to share this traffic data and information with the 511 Operations Center team quickly and conveniently, enabling the team to provide incident and construction data to the public via 511. In addition to providing the 511 Operations Center team with information on freeway conditions, Caltrans also informs motorists already on the road through overhead changeable message signs and highway advisory radio.

California Highway Patrol
The California Highway Patrol (CHP) is a major public partner in the 511 project. The CHP's Computer Aided Dispatch system provides important data to the 511 system on accidents, stalled vehicles, debris, etc. CHP's participation in 511 assists in achieving their goal of increasing safety on Bay Area freeways. Additionally, CHP personnel staff the Transportation Management Center (TMC) in Oakland and assist in managing the Freeway Service Patrol.

The Federal Highway Administration
The Federal Highway Administration (FHWA), a major agency within the U.S. Department of Transportation, is charged with the broad responsibility of ensuring that America's roads and highways continue to be the safest and most technologically up-to-date. Although State, local, and tribal governments own most of the Nation's highways, the FHWA provides financial and technical support to them for constructing, improving, and preserving America's highway system. The FHWA has an annual budget of more than $30 billion that is funded by fuel and motor vehicle excise taxes. FHWA is headquartered in Washington, DC, with field offices in every State, the District of Columbia, and Puerto Rico. The FHWA has served as a technical advisor on the 511 systems' implementation.
