Trinity Highway participated in a series of crash tests of the ET Plus® System as requested by the Federal Highway Administration (FHWA). It is important to note that these test outcomes were determined by data collected through the testing procedures, not just visual observations. Vehicle crashes are violent in nature, which is why the quantitative data collected through the testing process is so important.
These tests are complex. They involve the installation of hundreds of feet of guardrail, acquisition and instrumentation of the test vehicles, set-up of the vehicles and cameras, multiple equipment calibrations, and preparation and alignment of the test track.
ET Plus® System Testing Process
The tests were conducted at the Southwest Research Institute (SwRI) an independent, FHWA-approved testing facility in San Antonio, Texas. This facility has not participated in any previous tests of the ET Plus® System and has no financial interest in the product.
Previous ET Plus® System Testing
The Trinity ET Plus® System was crash tested in 2005 by Texas A&M Transportation Institute (TTI), an independent, FHWA-accredited testing facility, and met the required crash test criteria. The FHWA also reviewed two crash tests conducted in 2010 in which the ET Plus® System using four-inch guide channels met the required crash test criteria.
