Project Description/Scope/Purpose
This project provides for the replacement of traffic signal controllers, AATMS software, controller cabinets, communication equipment, and other components at approximately 15–20-year intervals due to new Federal and State requirements such as environmentally friendly components, NFPA Personal Safety requirements and obsolescence or changes in functionality. This project improves traffic flow at intersections and increases the reliability of the City's Traffic Management Center (TMC) systems, Intelligent Transportation Systems (ITS) components and other traffic signal equipment and helps enhance staff safety at the intersections.
The City operates and maintains a total of 138 traffic signals. The replacement costs, including contingency of the above equipment, vary depending on the location of the traffic signal. The replacement schedule is based on years of service, date of last upgrade, or as needed due to wear and tear. These ITS components, computer-based controllers, controller software, licensing fees for ATMS software that allows to communicate to all signalized intersections and other major control components deteriorate and are outdated with time and replacement parts become difficult to find as the equipment and software is phased out by the manufacturers or industry standards.
The Traffic Signal Controller Locations for replacement are as follows:
FY 2024/25 - Enterprise Way/Moffett Park-Manila Dr and Fair Oaks Ave/Old San Francisco Rd FY 2025/26 - Fair Oaks/Arques and Fair Oaks/Maude, Fair Oaks/Duane, Fair Oaks/Caliente, Fair Oaks/Ahwanee, Tasman/Reamwood and Java/Borregas, Hollenbeck/Torrington, Tasman/Adobe Wells-Birchwood, and Mary/Washington are expected to be replaced.
The future years will be programmed with the next CIP cycle.
Project Evaluation and Analysis
Traffic signal equipment slated for replacement do not meet City and/or industry standards, are obsolete, and parts are no longer available. In addition, this equipment will not integrate and communicate with current TMC systems. If not replaced, possible future failures will require immediate replacement that will cause a long-term shutdown of the Traffic Management Systems while equipment is ordered and delivered. Therefore, this equipment is essential to enhance the safety of pedestrians, bicyclists and vehicular traffic.
Fiscal Impact
Project costs are based on bids and prices from manufacturers and contractors. Costs are budgeted to replace three (3) controller cabinets and other ITS components per year. However, depending upon current market pricing for both material and labor costs adjusted for inflation, fewer locations and components could be replaced as scheduled.

Project Description/Scope/Purpose
This project provides funding for design and construction for replacement of traffic signal underground conduits and signal pole structures at the end of their estimated life span. Underground cables and conduits have a life expectancy of approximately 35 years. Signals identified for replacement are evaluated by location specific assessments based upon an inventory of traffic signal life cycles. The City has 138 traffic signals. Out of these, 72 percent are beyond their design life and are due for replacement.
The traffic signals at South Fair Oaks Avenue/California Avenue and S Bernardo Avenue/Heatherstone Way are being reconstructed in FY 2024/25.
The traffic signals at South Fair Oaks Avenue/E Olive Avenue, and W Maude Avenue/N Pastoria Avenue are being designed in FY 2024/25 and are expected to start construction in FY 2025/26.
For future projects, design and construction for two traffic signals will be performed every three years. Bernardo/Washington, Mary/Knickerbocker, and Mary/Cascade will be designed in FY 2026/27 and FY 2027/28 and constructed in FY 2028/29.
Mary/Ticonderoga, Mary/Remington, and Wolfe/Old San Francisco Road will be designed in FY 2029/30 and FY 2030/31 and constructed in FY 2031/32.
Project Evaluation and Analysis
Underground conduits/substructures, as they age and corrode, become filled with dirt and water and cannot be cleaned. Failure to replace systems may result in wire failure in the future with no means of quick replacement and signal shutdown for multiple days until replaced. Traffic signal poles and associated hardware are evaluated for replacement concurrently in order to consider updated design standards and condition of infrastructure. Project costs are based on bid history and construction prices received.
Fiscal Impact
The budget provided is sufficient for three signals per three-year cycle. Project costs are based on bid history and construction prices received. Near term funding levels are calibrated to match conditions in the field.
