State departments of transportation employ numerous variations of luminaire and sign support systems that require evaluations for their crashworthiness. Guidelines for families of devices with similar crashworthy performance have the potential to reduce costs and promote compliance with the Manual for Assessing Safety Hardware (MASH).
NCHRP Research Report 1123: Guidelines for Evaluating Crashworthiness of Sign Supports and Breakaway Luminaire Poles, a pre-publication draft from TRB’s National Cooperative Highway Research Program, presents research results and preliminary guidelines for evaluating families of devices for sign supports and breakaway poles under MASH.
