A new pilot project is now underway along an eight-mile stretch of northbound Interstate 15 (I-15) between Temecula and Murrieta in Riverside County. Described by backers as a “smart freeway,” the $33 million project aims to ease congestion through real-time traffic management, using sensors, ramp meters, and coordinated system controls along the corridor.
At a high level, the project has a clear purpose and need and it largely achieves it. This segment of freeway is now equipped with advanced monitoring systems that collect data on speeds, volumes, and travel times. That data feeds into ramp meters that regulate how many vehicles can enter the freeway at a given time, while digital message signs display recommended speeds to smooth traffic flow. According to the Riverside County Transportation Commission (RCTC), the goal is straightforward: reduce stop-and-go conditions, improve safety, and make travel times more reliable along one of the Inland Empire’s most congested corridors.
Yet despite being labeled a “smart freeway,” the project reflects a fundamentally narrow definition of what “smart” means. Over the long term, a more intelligent approach would re-envision the I-15 corridor to prioritize the safety and movement of people across multiple modes, including buses, bicyclists, and pedestrians, not just automobiles…
