The objectives of the study are to: (1) review current truck escape ramp literature; (2) document all acceptable designs; (3) determine any and all shortcomings in the current method of arresting heavy vehicles and recommend specific research needs to eliminate these deficiencies; and (4) develop a framework of information, criteria, and specifications concerning truck escape ramps such that national design standards may later be developed. Design aspects are manifested in six types of truck escape ramps: sandpile, gravity ramp, ascending grade arrester bed, horizontal grade arrester bed, descending grade arrester bed, and roadside arrester bed. Interim guidelines are provided for the design of truck escape ramps.
