• Abstract:
  From September 2015 to the end of January 2019, the Federal Highway Administration partnered with departments of transportation in California, Massachusetts, Missouri, and Pennsylvania, as well as the Pennsylvania Turnpike Commission, to perform a proof of concept for a methodology for data collection of w-beam guardrail end terminals. Data collectors took photographs and recorded observations at crash scenes in which passenger vehicles experienced a head-on crash with the impact heads of common guardrail terminals, including the ET 2000, ET Plus® with both 4- and 5-inch guide channels, Sequential Kinking Terminal (i.e., SKT), MASH-compliant Sequential Kinking Terminal (i.e., MSKT), FLared Energy Absorbing Terminal (i.e., FLEAT), X-Lite, X-Tension®, and MAX-Tension™. The pilot study demonstrated that highway agencies can collect performance data of guardrail terminals by integrating in-service performance data-collection procedures into their normal crash-response activities.
