Projects include region-wide advanced traffic signal synchronization and cloud-based pilot along McFadden Avenue
SANTA ANA, CA – February 23, 2026 – Arcadis, a global leader in intelligence-driven sustainable design, engineering, and consultancy solutions for natural and built assets, today announced its selection to deliver two projects that accelerate the modernization of mobility access across Santa Ana and Orange County. The projects, valued at a combined $6.6 million, include the Kraemer Boulevard/Glassell Street/Grand Avenue Corridor Regional Traffic Signal Synchronization Project and the McFadden Avenue Transit Signal Priority (TSP) Pilot Project.
Under a $5.4 million, three-year contract, Arcadis will deliver turnkey services for the Kraemer Boulevard/Glassell Street/Grand Avenue Corridor Regional Traffic Signal Synchronization Project. Spanning a 15-mile corridor and 61 signalized intersections across six communities, including Santa Ana, Orange, Anaheim, Placentia, Brea, and Caltrans, this project represents a step toward safer and more efficient regional mobility. Arcadis will also upgrade traffic signals and communication infrastructure, install new cabinets, and optimize signal timing to ensure seamless coordination with adjacent arterial signals. These enhancements are designed to deliver smoother traffic flows, minimize congestion, and empower agencies with state-of-the-art tools for advanced traffic and asset management.
These efforts continue to build on Arcadis’s expansion in California, focused on integrating technologies that reduce travel times, fuel consumption, and emissions while improving mobility for all users.
Additionally, Arcadis has been awarded a $1.1 million contract to deliver a cloud-based Transit Signal Priority system pilot for Orange County along McFadden Avenue. The pilot will cover 19 intersections, deploying a cloud-based TSP system to support OCTA’s Bus Line 66. This project evaluated four potential TSP solutions to select the system that best meets the needs of both the City of Santa Ana and OCTA, providing a more reliable and efficient bus service for residents who rely on public transit for daily commutes to work, school, and local shopping.
Cesar Rodriguez, City of Santa Ana Public Works Senior Traffic Engineer, said: “The regional traffic signal synchronization project will empower all participating agencies to better coordinate signal operations, respond swiftly to traffic incidents and special events, and manage their transportation networks more effectively. In addition, the McFadden pilot will help improve the experience for bus travelers without negatively impacting regular traffic flow, ensuring a win-win for both transit users and motorists. Upon completion, both projects will optimize signal timing, improve traffic flow, enhance coordination, and data exchange, which will benefit the local communities at large.”
Ramin Massoumi, Global Business Area Director for Mobility at Arcadis, said: “Arcadis is honored to partner with the City of Santa Ana, OCTA, and its regional stakeholders on these forward-thinking projects. By leveraging technology and our deep local expertise, we will deliver robust and modern traffic management and transit solutions that support real-time responsiveness and asset longevity. Our integrated approach for both projects will help reduce congestion, improve safety, and enhance the daily experience for thousands of residents and commuters.”
