Comparison of the E.D.R. Data to the Test Deceleration Events for a Kenworth T680 Tractor

In February 2015, the University of North Florida, Institute of Police Technology and Management (IPTM) conducted a Heavy Vehicle Event Data Records (HVEDR) course that included an Emergency Vehicle Operations Course (EVOC) track where heavy tractors were tested. In this article, the authors report the results of test deceleration events for a 2014 Kenworth T680 tractor. Three tests were conducted, consisting of heavy braking applications that brought the tractor to a complete stop. The article reports on the results of braking tests, issues related to the tractor’s imaging process, and Fast Stop Recorder data.
