Low-cost end treatments for concrete barriers and crash cushions/impact attenuators are explored and described for low- speed (40 mph or less) highways. Various proprietary and non- proprietary end treatments have been developed and used in recent years, but most of these systems are costly and are designed for an impact speed of up to 60 mph. As part of the process of collecting information on these devices, a number of selected State DOTs were contacted to obtain their experiences in using crash cushions/impact attenuators on their low-speed highways. While most of the DOTs contacted have been using these systems at hazardous locations on low-speed highways they felt that there is a need for inexpensive low-speed crash cushions and attenuators which would serve the purpose at such locations. Research reports, vendor literature, and contacts with State DOTs yielded 25 different barrier and treatment systems, and these are described in this report.
