Curve Warning System
Vehicles are more likely to leave the travel lane of a roadway where the roadway alignment changes direction. These locations are known as horizontal curves.
Curve warning system is the most effective solution to reduce crashes. By FHWA, installation of curve warning system resulted in a 39 percent reduction in California.
30% of crash is related to curves. The roadway departures cause severe casualties.
Approximately 75 percent of the curve-related fatal crashes involve single vehicles leaving the roadway and striking objects.
The average single-vehicle run-off-road crash rate was 3 times higher on horizontal curves than on tangent segments.
