M it' Over the past three years from 2023 to 2026, the City, in cooperation with OCTA and other local agencies, participated in synchronizing several important corridors in the City and adjacent jurisdictions. Many corridors have been previously synchronized and maintained, however due to changes in traffic patterns, periodical re-timing is necessary to maintain progression and reduce delay. Since 2023, The following corridors were synchronized or currently in the process of implementation: • Synchronization for the First Street-Bolsa Avenue and Tustin Avenue-Rose Drive Corridors were completed in 2024. • Synchronization for the Warner Avenue Corridor was completed in 2025. • Synchronization for the MacArthur Boulevard Corridor was completed in 2026. • Synchronization for the Edinger Boulevard Corridor was completed in 2026. • Synchronization for the Segerstrom Avenue/Dyer Road Corridor was completed in 2026. A. Performance Results: The primary objective of improving traffic flow along each synchronized corridor was achieved across all corridors included in recent synchronizations efforts. Improvements were observed in all key performance measures, including reduced travel times, fewer stops, higher average speeds, and improved green-to-red-signal ratios. These enhancements collectively indicate more efficient progression and better overall corridor performance. A summary of these improvements is shown on Table 6 (Traffic Signal Synchronization Assessment, Review& Revision). These results are based on findings from the `Before' and `After' Studies conducted as part of the Primary Implementation Phase Reports for each project. The assessment breaks down the performance by corridor, direction of travel, and time of day, providing a detailed evaluation of operational changes resulting from the synchronization efforts.
