Abstract:The purpose of roadside barrier systems is to reduce the severity of injuries and number of fatalities by controlling and mitigating crash forces. While barrier systems have been designed and proven to be beneficial for motor vehicles they do not currently address the problems associated with motorcycle crashes. This synthesis of research presented in this report concludes that motorcyclists are more vulnerable than drivers of motor vehicles and that motorcyclists are more likely to be severely injured when they crash into a barrier system. Addressing the challenges associated with barrier systems is critical for reducing the severity of injurious and number of fatalities associated with motorcyclist-barrier crashes. The synthesis report summarized several new barriers and retrofit systems currently used or under development that are specifically intended to improve motorcyclist safety in addition to retaining the existing benefit for motor vehicles. This synthesis report identifies current research proposals and research gaps that should be considered for future research projects. A significant gap is the lack of testing standards and protocols in the United States to verify the safety advantages of roadside barriers for motorcyclists. The final portion of this report summarizes testing parameters to be considered for both upright and sliding impacts into roadside safety barriers that should be investigated during the planning, development, and research of testing standards in the United States.
