Low Cost Treatments for Horizontal Curve Safety

Course Summary

Nearly 25 percent of fatal crashes occur at or near a horizontal curve. Hence, addressing the safety problem at horizontal curves is one of the 22 emphasis areas of the Strategic Highway Safety Plan prepared by AASHTO. Also, crashes at horizontal curves are a big component of the road departure crash problem, which is one of FHWA’s three focus areas. This course was prepared to provide practical information on low-cost treatments that can be applied at horizontal curves to address identified or potential safety problems. The course concisely describes the treatment; shows examples; suggests when the treatment might be applicable; provides design features; and where available, provides information on the potential safety effectiveness and costs.
