City of Santa Ana Local Signal Synchronization Plan The primary goal is to maintain a safe and efficient transportation network with emphasis on traffic signal synchronization along major corridors. This Local Signal Synchronization Plan will serve as a guide for the implementation and maintenance of optimized signal timing along these corridors. The objective is to reduce delay, number of stops, fuel consumption and air pollution emissions and maximizing the traffic progression through the system. A key focus of the City is improving safety of all roadway users. A well-timed, synchronized system will reduce collisions as a result of improved traffic flow and will minimize diversion of traffic to local and residential neighborhoods improving safety and traffic conditions in those areas. Along with providing optimized signal timing, the City is also focused on providing key technology improvements for pedestrian accessibility, bicycle detection and emergency vehicle pre- emption, allowing for much safer travel through the signal system. The City has been synchronizing its traffic signals since the 1970's with the implementation of the Multisonics Vehicle Management System. Since then the City has continued to upgrade and improve its traffic signal infrastructures and operations. The City's major effort in improving its traffic signal operations and infrastructures began in early 1990's when the City received numerous funding from State of California Transportation System Management grants to implement an Advanced Traffic Management System that included traffic communication infrastructure, new traffic signal system and incorporated many elements of Intelligent Vehicle Highway System such as CCTV, Video detection, and Changeable Message Signs (CMS). The City continues to actively upgrade traffic signal communications infrastructure to Fiber Optic technology allowing for faster and more reliable communication to support synchronization between intersections and the central ATMS system. Recognizing the needs to maintain uninterrupted traffic flow through adjacent agencies, the City started to work with Caltrans in early 1990's for the City to maintain and operate majority of Caltrans' ramp traffic signals in Santa Ana so they can be synchronized with local traffic signals. Similarly, in 1992, the City of Fountain Valley agreed to share the operation of its traffic signals on Harbor Blvd with Santa Ana so Harbor Blvd can be synchronized throughout both cities.
