Description

TRB's National Cooperative Highway Research Program (NCHRP) has released a pre-publication, non-edited version of Research Report 894: Evaluating the Performance of Longitudinal Barriers on Curved, Superelevated Roadway Sections. Curved, high-speed roadways are usually superelevated to make the curved roadway easier for vehicles to navigate. However, the angle of these roadways can cause an increase in impact loading that may potentially exceed the capacity of barriers along roadway sections. The report presents guidance on designing, selecting, and installing longitudinal traffic barriers for curved, superelevated roadways for possible incorporation in the American Association of State Highway and Transportation Officials (AASHTO) Roadside Design Guide.
