Development of a MASH Barrier to Shield Pedestrians, Bicyclists, and Other Vulnerable Users from Motor Vehicles

The objective of this research is to develop a minimum of one nonproprietary barrier design for use in separating vulnerable users from motor vehicle travel lanes that is tested to appropriate Manual for Assessing Safety Hardware (MASH) criteria, complies with Public Right-of-Way Accessibility Guidelines (PROWAG), and is cost-effective. An acceptable design could be for a completely new barrier or one that modifies an existing barrier. The barrier design shall provide positive protection by redirecting motor vehicles and include design elements that also increase safety of vulnerable users. The barrier design should be appropriate for commonly encountered design contexts.
