SALINAS, Calif. (KSBW) — Caltrans has implemented adaptive artificial intelligence technology to control traffic lights at nine intersections along Highway 68, aiming to reduce congestion and improve travel times.
The installation, which began wrapping up in January, spans from Josselyn Canyon Road to San Benancio Road and is part of a five-year, $500,000 pilot project.
“This is actually the first full corridor utilizing AI adaptive traffic signal control on any state highway system in California,” said Kevin Drabinski, Public Information Officer for Caltrans District 5.
One of the intersections at York Road is included in the project, which offers a significantly cheaper alternative to the more than $200 million Scenic Route 68 Corridor Improvement Project roundabout plan that faced heavy pushback from drivers.
Instead of roundabouts or major road expansions, these signals use real-time traffic data to adjust green lights and keep cars moving.
Drivers in Corral de Tierra have expressed openness to the change, with Tisa Noland saying, “It seems like an intelligent use of AI. Let’s find out.”
Caltrans has stated that while the equipment is installed, the system is still being calibrated, with full optimization expected by May.
“While the equipment is in place, it takes several months to calibrate and to adjust,” Drabinski said.
Drivers have noted the increasing presence of AI in daily life.
“That doesn’t bother me. It’s everywhere, you know, as long as it helps, I don’t. I don’t have a problem with that,” Carrie Askey said.
Roland suggested patience with the new system, saying, “I think we should stick with this for a while. Give it time.”
Caltrans plans to monitor the performance of the signals over the next five years and make adjustments as necessary.
