Signal synchronization is a cost-effective way to minimize congestion by improving street and road capacity without costly and disruptive new construction. Projects throughout the county have been funded by a variety of local, state, and federal sources.
Summary
The Measure M2 Regional Traffic Signal Synchronization Program (RTSSP), also known as Project P, provides funding and assistance to implement multi-agency signal synchronization. The target of the program is to regularly coordinate 2,000 signals along 750 miles of roadway as the basis for synchronized operation across Orange County.
To date, OCTA and local agencies have synchronized more than 2,000 intersections along more than 600 miles of streets (or 69 completed projects). The OCTA Board of Directors, through a competitive process, have approved eight rounds of M2 funding for Project P. On June 11, 2018, the Board awarded $8.9 million dollars to six projects as part of the 2018 Call for Projects Regional Traffic Signal Synchronization Program (RTSSP). OCTA staff leveraged the M2 funding for $6.6 million from SB-1 to fully fund all Call 8 Project P applications. To date, this program has provided a total of 103 projects totaling more than $98 million, including $18 million in external funding.
34 projects are planned or in progress through Project P. As of October 2018, the program has resulted in:
- 69 completed signal synchronization projects
- $98 million in funding awarded by the OCTA Board of Directors
- Approximately $46 million in improvements along 613 miles and 2,367 signals
- Travel time savings: 13%
- Speed improvements: 15%
- Stop reduction: 31%
- $144.5 million estimated project life gas savings
- 750 million pounds of Greenhouse Gas savings
Signal Synchronization from 2007 to 2011
After completing two signal synchronization demonstration projects on Euclid Street and Oso Parkway/Pacific Park Drive that comprised of 86 signals and 24 miles through eleven jurisdictions, OCTA advanced signal synchronization efforts along ten arterial corridors comprised of 585 signalized intersections on 158 miles of roadway. This $8 million effort was funded by Proposition 1B Grants and the Measure M1 Traffic Light Synchronization Program (TLSP). The ten projects helped eased drivers traveling throughout the county.
In 2011, OCTA implemented signal synchronization along three more corridors (Harbor Boulevard, State College Boulevard-Bristol Street, and Westminster Avenue) as transportation control measures for the purpose of reducing emissions by reducing congestion conditions. The corridors included 252 signalized intersections and 46 miles of roadway through ten jurisdictions. The project budget was $1.8 million and was funded by federal transit and air quality revenues. OCTA also funded an additional corridor with M1 funds totaling $520,000. The Magnolia Street corridor synchronized 53 signals along 16 miles of roadway through seven jurisdictions.
