• Abstract:
  Roadside signs are critical to traffic control. ; However, if not properly designed to yield ; upon vehicle impact, these signs become lifethreatening ; hazards. Yet, the signs must be able ; to withstand wind loading, in Florida, up to ; hurricane force winds. In a disaster, a collapsed ; sign poses two dangers: drivers no longer receive ; the sign’s information, and it can obstruct traffic ; lanes. Current sign supports ; meet these challenges, but ; their breakaway mechanism ; is undesirably sensitive to the ; accuracy of the torque that is ; imposed on the bolts during ; installation and maintenance.
