Design completed for Main St. traffic signal synchronization

The City of Santa Ana’s Public Works Engineering team recently completed the design for the Main Street Regional Traffic Signal Synchronization Project which is scheduled to start construction in September 2020 with completion anticipated in December 2020.

The project is in partnership with Orange County Transportation Authority (OCTA), and will provide inter-jurisdictional traffic signal synchronization in addition to improvements along the Main Street corridor traversing the City of Santa Ana, Orange, Irvine and Caltrans jurisdictions. The project limits are from Taft Avenue in City of Orange through the City of Santa Ana to Culver Drive in City of Irvine (see Figure 1 illustration). There are total of 67 traffic signals and the project length is approximately 11.9 miles.

The project will provide new traffic signal synchronization plans and necessary infrastructure improvements to implement, monitor and maintain the new timing. Improvements include communication conduits, cables and hardware; traffic signals cabinets and controller upgrade, Traffic Management Center software and hardware upgrades as well as field monitoring equipment such as system detectors and CCTV’s to support and maintain the new synchronization plan. The project also provides funds to maintain the synchronization for additional two years after the initial timing implementation.

The estimated cost to complete the project is $4,663,729, where $3,899,185 (80%) is Measure M2 Grant funding and $764,544 (20%) is matching funds from the participating Cities. The City of Santa Ana’s portion is $1,680,450 million in improvements with $336,090 matching funds.

Diseño Terminado para Sincronización de Semáforos Regional

El equipo de Ingeniería de Obras Públicas terminó recientemente el diseño para el Proyecto de sincronización de semáforos regional de la Calle Main, que está programado para iniciar la construcción en septiembre del 2020, y se anticipa su conclusión en diciembre del 2020. El proyecto se realiza en alianza con la Autoridad de Transporte del Condado de Orange (OCTA), y proveerá sincronización de semáforos interjurisdic¬cional, junto con mejorías en el corredor de la Calle Main que traversa las jurisdicciones de las ciudades de Santa Ana, Orange e Irvine, y Caltrans. Los linderos del proyecto van de la Avenida Taft Avenue en la Ciudad de Orange a través de la Ciudad de Santa Ana a Culver Drive en la Ciudad de Irvine (véase la ilustración de la Figura 1). Hay un total de 67 semáforos y la longitud del proyecto es de aproximadamente 11.9 millas.

El proyecto proveerá planes nuevos de sincronización de semáforos y mejorías de infraestructura necesarias para implementar, vigilar y mantener la nueva sincronización. Las mejorías incluyen conductos, cables y equipo de comunicación; gabinetes de semáforos y actualización de controladores, programa del Centro de Gestión de Tránsito y actualizaciones de equipo, al igual que equipo de vigilancia de campo, como sistema de detectores y cámaras de circuito cerrado para apoyar y mantener el nuevo plan de sincronización. El proyecto también brinda fondos para mantener la sincronización por dos años adicionales luego del tiempo de implementación inicial.

El costo calculado para completar el proyecto es $4,663,729, donde $3,899,185 (80%) son fondos de la Medida M2 y $764,544 (20%) son fondos paritarios de las Ciudades participantes. La porción de la Ciudad de Santa Ana es $1,680,450 en mejorías con $336,090 de fondos paritarios.
