Abstract:Alternatives to existing transportation truck escape ramps and crash barriers are examined using arrays of
wood, bamboo, and fiberglass structural elements that act as energy absorbers as they deform. The
behaviors of each material type are analyzed to determine if they have the necessary potential for
extensive use in such applications.Calculations based upon static and dynamic testing are made to predict
the type of system required to bring vehicles to a stop. The findings are discussed and guidelines for
future applications are suggested.
