California’s first ‘smart freeway’ just opened with a $33M AI-plan to crush traffic congestion

Eight-mile northbound I-15 Temecula-Murrieta is home to California's first smart freeway pilot using AI and sensors.
The system uses coordinated ramp meters that communicate in real time to adjust entry based on traffic ahead.
Officials warn drivers may experience short delays at on-ramps as the system optimizes flow.
The project aims to reduce stop-and-go traffic, improve travel times, and cut emissions by minimizing idling.
The Riverside County Transportation Commission chairs say the project supports technology-infused infrastructure.
The pilot is a collaborative effort with multiple regional and federal partners for a two-year study.
Caltrans and local agencies highlight potential safety, efficiency, and environmental benefits.
The eight-mile northbound corridor runs from the San Diego/Riverside County line to the I-15/I-215 interchange.
Officials describe the pilot as smoother rides and improved flow once drivers get onto the freeway.
The project underscores a shift from traditional lane expansion to technology-driven traffic management.
