• Abstract:
  This report provides an analysis of single vehicle roadway departure (SVRD) crashes to guide the development of Intelligent Vehicle Highway Systems (IVHS) crash avoidance systems. It introduces the problem of SVRD crashes: A crash is defined as a SVRD when the first harmful event is the departure from the roadway, thus excluding departures resulting from prior impacts. Two crash subtypes are identified and causal factors that contribute to SVRD crashes are assessed clinically from a sample of SVRD crashes. From these data, functional goals for IVHS SVRD crash avoidance systems are described. Three simple models of potential kinematic remedies to pre-crash scenarios are examined: stopping the vehicle, steering to return to the original travel lane, and slowing the vehicle to a safer speed. These models illustrate the distances and time's needed to prevent crashes. The report concludes with a discussion of key research needed to extend the analysis presented.
