      <title>Testing of South Dakota Sign Support System, Foil Test Numbers: 9SF005 and 95F006</title>
      <link>https://trid.trb.org/View/2520995</link>
      <description><![CDATA[This test report contains the results of two crash tests performed at the Federal Outdoor Impact Laboratory (FOIL) in McLean, Virginia. The tests were performed on a small sign support system at 35 km/h, test 95F005 and at 100 km/h, test 95F006. The vehicle used for the tests was a 1986 Honda Civic. The purpose of these tests was to evaluate the low- and high-speed safety performance of the South Dakota red cedar post sign support. The sign support was made from a 102-mm by 152-mm western red cedar wood post. No holes were drilled in the posts, and the posts were buried 1.2 m in weak soil. The performance evaluation was based on the latest requirements for breakaway supports as specified in the National Cooperative Highway Research Program (NCHRP) Report 350. These criteria specify, in part, that the occupant change in velocity must be 5 m/s or less, that the significant test article stub height remaining after impact be no more than 102 mm, and that there be no occupant compartment intrusion. The test results indicate that the western red cedar wood post sign support system meets all of the applicable safety criteria for low-speed and high-speed tests in weak soil as specified by the Federal Highway Administration (FHWA).]]></description>

      <title>Crashing Through COVID-19: How FHWA Kept Its Outdoor Impact Laboratory Going</title>
      <link>https://trid.trb.org/View/2132209</link>
      <description><![CDATA[During the COVID-19 pandemic, the Federal Highway Administration's (FHWA's) Federal Outdoor Impact Laboratory (FOIL) continued to perform onsite inspector-certified crash tests. To be able to continue work at the FOIL, during the pandemic, two main challenges had to be addressed: social distancing and the ability to communicate with partners. This article discusses the solutions FOIL implemented to accommodate external partners who would normally have visited the facility. Using digital still photography cameras and a readily available collaboration and communication software platform, the FOIL team was able to provide FOIL partners with a live, multiple-perspective view of crash tests.]]></description>

      <link>https://trid.trb.org/View/1889556</link>
      <description><![CDATA[This report contains the test procedures followed and test results from five frontal and one broadside crash test between 1997 Geo Metros and the FOIL instrumented 300K rigid pole. The tests were conducted at the Federal Highway Administration's (FHWA's) Federal Outdoor Impact Laboratory (FOIL) located at the Turner-Fairbank Highway Research Center (TFHRC) in McLean, Virginia. The target test speed for each test was 35 km/h and the target test weight (no dummy was used for these tests) was 820 kg. The crush profile, electronic data, and high-speed film from these tests will aid computer simulation engineers in developing and validating finite element models of the Geo Metro and roadside safety hardware. The data will also be used to redesign the reusable honeycomb nose of the FOIL bogie vehicle to resemble the crush stroke of the Geo Metro.]]></description>

      <title>Pendulum Impact Testing of Steel W-Beam Guardrail, FOIL Test Numbers: 94P023-94P027, 94P030, and 94P031</title>
      <link>https://trid.trb.org/View/863160</link>
      <description><![CDATA[This contains the test results from a series of seven pendulum impact tests conducted at the Federal Outdoor Impact Laboratory (FOIL) pendulum facility located at the Turner-Fairbank Highway Research Center (TFHRC) in McLean, VA. The purpose of this study was to develop an optimal testing procedure to determine the dynamic response for steel guardrail sections so that the behavior of a rail can be evaluated without conducting full-scale vehicle crash tests with autombiles. Standard steel w-beam rail sections were tested in this study; however, the test procedure eventually developed is expected to be used for the evaluation of rails composed of other materials, such as glass fiber-reinforced composite materials.]]></description>

      <title>CRASH TEST BETWEEN A 6-KG/M U-CHANNEL SIGN SUPPORT AND A 1997 GEO METRO: FOIL TEST NUMBER 99F010</title>
      <link>https://trid.trb.org/View/690553</link>
      <description><![CDATA[This report contains the test procedures followed and test results from one crash test between a 1997 Geo Metro and a single-leg small sign support.  The test was conducted at the Federal Highway Administration's Federal Outdoor Impact Laboratory (FOIL) located at the Turner-Fairbank Highway Research Center in McLean, Virginia.  The target test speed for the test was 100 km/h and the target test inertial weight was 820 km.  A dummy was not used in this crash test.  The test was conducted to provide data for validating a finite element model (FEM) of a Geo Metro and to investigate the potential for windshield penetration by the sign support after fracture. Computer simulations using the latest FEMs of a Geo Metro indicated that windshield penetration was possible while striking a small sign support with a sign panel mounting height of 1,525 mm.  The results from the test verified the simulation's prediction that if a Geo Metro struck this particular sign support design with these material properties there was a high probability of windshield penetration or severe windshield/roof damage.  Because the post fractured, other important safety performance measures including predictability of device activation and longitudinal occupant impact velocity met the safety performance criteria specified in the National Cooperative Highway Research Program (NCHRP) Report 350, test designation 3-61.  The data and high-speed film coverage will aid in the continuing evolution of the Geo Metro FEM.]]></description>

      <link>https://trid.trb.org/View/503373</link>
      <description><![CDATA[This report contains the test procedures, test setup, and test results from two crash tests performed at the Federal Outdoor Impact Laboratory (FOIL) located at the Turner-Fairbank Highway Research Center (TFHRC) in McLean, Virginia.  The objective of these tests was to evaluate the safety performance of a small sign support system provided by the Oregon Department of Transportation (DOT) and to provide Federal Highway Administration (FHWA) finite element model simulation engineers with data on the performance of a slip-base sign support. Previous tests on large Oregon slip-base sign supports conducted at the FOIL demonstrated an improvement in safety performance by increasing the previous bolt-notch angle from 60 deg and 90 deg.  The change was implemented into a small slip-base sign support design and tested at the FOIL.  This report documents the results from two crash tests using the FOIL bogie vehicle and the Oregon DOT's 3X3 TBB sign support.  The tests were conducted at nominal test speeds of 35 km/h and 100 km/h.  The sign support met the FHWA safety performance criteria outlined in National Cooperative Highway Research Program (NCHRP) Report Number 350.]]></description>

The test was conducted at the Federal Highway Administration (FHWA) FOIL located at the Turner-Fairbank Highway Research Center (TFHRC) in McLean, Virginia.  The National Highway Traffic Safety Administration (NHTSA) enlisted the FHWA to aid in the development of laboratory test procedures to be used in a revised or amended version of Federal Motor Vehicle Safety Standard (FMVSS) 201 (Occupant Protection in Interior Impact). This new test procedure could be used in the evaluation of dynamic side-impact protection systems (e.g., air bags).  Steps were taken to ensure accurate, repeatable test procedures so that test facilities abroad would achieve similar results given comparable test conditions.  The NHTSA supplied a calibrated SIDH3 dummy.  The head injury criteria (HIC) and thoracic trauma index (TTI) values were used to determine the severity of the test and as a comparison between subsequent broadside tests to evaluate the repeatability of the test procedures.]]></description>
