'Smart studs' will control traffic flow at busy interchange

Mercer 623

Caltrans

The Pasadena Freeway (SR-110) was built in 1940, and originally carried 27,000 vehicles. Today, Average Annual Daily Traffic volume at the northbound SR-110 connector to I-5 is 127,000.

Caltrans is installing a technology called “smart studs” to ease congestion on the connector from the 110 North to the northbound 5 freeway. The "smart studs" are markers that will light up to control traffic on the connector road. Frank Quon is deputy district operations director for Caltrans. KPCC's Kari Moran spoke with Quon about how the program will work.
