Safety Performance Testing of a Modified Oregon Multidirectional Slip-Base Sign211 Support: FOIL Test Numbers 98F002 and 98F004

摘要

This report contains the test procedures, test setup, and test results from two211u001ecrash tests performed at the Federal Outdoor Impact Laboratory (FOIL) located at 211u001ethe Turner-Fairbank Highway Research Center (TFHRC) in McLean, Virginia. The 211u001eobjective of these tests was to evaluate the safety performance of a small sign 211u001esupport system provided by the Oregon Department of Transportation (DOT) and to 211u001eprovide Federal Highway Administration (FHWA) finite element model simulation 211u001eengineers with data on the performance of a slip-base sign support. Previous 211u001etests on large Oregon slip-base sign supports conducted at the FOIL demonstrated 211u001ean improvement in safety performance by increasing the previous bolt-notch angle 211u001efrom 60 degrees and 90 degrees. The change was implemented into a small slip-base 211u001esign support design and tested at the FOIL. This report documents the results 211u001efrom two crash tests using the FOIL bogie vehicle and the Oregon DOT's 3X3 TBB 211u001esign support. The tests were conducted at nominal test speeds of 35 km/h and 100 211u001ekm/h. The sign support met the FHWA safety performance criteria outlined in 211u001eNational Cooperative Highway Research (NCHRP) Report Number 350.
