Impact Performance Assessment of Barrier Performance at High Speeds

The objectives of this research are the following: (1) Assess the performance of existing, non-proprietary longitudinal barriers on roadways with posted speeds of 75 mph and higher. (2) Identify needs for barrier test criteria at these higher speeds. (3) Develop, as needed, barrier test parameters that could be considered for future criteria and crash testing. At a minimum, these parameters shall include test vehicles, impact speed, angle of impact, and required impact results. (4) Develop cost-effective barrier design(s) to meet the developed test parameters and verify performance of the design(s). This research shall evaluate existing, non-propriety barrier designs and exclude proprietary barrier, transition, and terminal designs.
