  • Abstract:
    While most transportation agencies are very familiar with truck-mounted attenuators, trailer-mounted ; attenuators are increasing in popularity. There is a concern for the level of protection that attenuators ; provide for workers when they are mounted on trailers compared to trucks. This research evaluated and ; compared the level of protection provided to workers by truck-mounted and trailer-mounted attenuators. No ; crash testing was conducted; instead, the researchers used existing crash test report data for the comparison. ; The researchers found that the use of heavier support vehicles for these mobile attenuators provided better ; protection for workers and recommend that TxDOT maintains the current policy of requiring 20,000 lb ; support vehicles, regardless of attenuator type. In addition, the researchers found that the concern of trailermounted ; attenuators swinging around may not be justified, given that post-impact trajectories of the ; impacting vehicles are similar to those reported during truck-mounted attenuator impact testing.
