Weather has significant safety impacts on the roadway system. Icy pavements can significantly reduce the coefficient of friction between automobile tires and road surfaces, and impair the ability of drivers to operate their vehicles safely. Improving traffic safety under icy conditions is of importance to many state transportation departments. To this end, the California Department of Transportation (Caltrans) has deployed an Icy Curve Warning System (ICWS) on a five-mile 6 segment of State Route 36 in Lassen County. This section of roadway has a history as a high-crash location with fatal crashes, the vast majority of which occurred during icy pavement. The objective of this study was to evaluate operational effects of the ICWS, specifically on speeds during various conditions.
