Sacramento River Canyon Curve Warning Systems

Started: June, 1998 Ended: August, 1999 Project ID #429861 Status: Completed


To evaluate five different dynamic curve warning systems that were installed for advance notification to motorists of alignment changes and speed advisories in the Sacramento River Canyon.


Interstate 5 between Redding and Dunsmuir, the area known as the Sacramento River Canyon, was selected as the demonstration site for the dynamic curve warning system because of its high traffic volumes, mountainous terrain and the number of crashes specifically related to heavy trucks.
