With increased traffic, multilane highways and complex highway interchanges, highway signs play an ever more important role in the safe operation of the nation's transportation network. A detailed understanding of stresses during the service life of sign support structures is crucial for their safe and economic design. The TRB National Cooperative Highway Research Program's NCHRP Research Report 1012: Wind Drag Coefficients for Highway Signs and Support Structures develops comprehensive methods for estimating wind loads and the associated drag coefficients for highway signs and overhead support structures for inclusion in the AASHTO Load and Resistance Factor Design Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals.
