• Abstract:
  This report describes a study of ramp signing for trucks. The research addressed methods for treating interchange ramps that are prone to cause high center of gravity vehicles to lose control and overturn. A critical review of the pertinent literature on interchange ramp design, signing, and overturning truck accidents was conducted. A state-of-the-practice review was also conducted in 12 states. This review determined the nature and extent of the truck rollover accident problem, determined problem ramp identification procedures, and identified active and passive treatments currently being used at problem ramps. A "design-a-sign" study was conducted using 61 professional truck drivers. This study attempted to identify critical ramp characteristics and to develop innovative procedures for effectively communicating this information to approach drivers.
