A recently completed traffic signal interface between the City and County of Los Angeles will dramatically improve traffic flow throughout the region.

The new interface links the City’s Advanced Traffic Control System with the County’s Information Exchange Network, and will enable a two-way exchange of traffic signal data, including congestion and incident information. It will significantly enhance the ability for both agencies to work together to ensure their traffic signals remain coordinated across City boundaries. Operators in both agencies will be able to monitor the operation of each agency’s signals and make adjustments to ensure the routes are synchronized.

The total cost of the project was approximately $1.41 million, with funding provided by the Mobile Source Air Pollution Reduction Review Committee, the Metropolitan Transportation Authority, and the City and County of Los Angeles.
