• Abstract:
  This paper prioritizes and statistically describes precrash
  
  scenarios as a basis for the identification of
  
  crash avoidance functions enhanced or enabled by
  
  vehicle-to-vehicle (V2V) communication technology.
  
  Pre-crash scenarios depict vehicle movements and
  
  dynamics as well as the critical event immediately
  
  prior to the crash. The prioritization of pre-crash
  
  scenarios is based on the societal harm from persons
  
  who were injured in pre-crash scenarios involving at
  
  least two vehicles. The crash must also involve at
  
  least one light vehicle (e.g., passenger car, van,
  
  minivan, sport utility vehicle, or pickup truck) with a
  
  gross vehicle weight rating less than 4,536 kg. This
  
  paper also introduces a framework that serves to
  
  connect pre-crash scenarios to crash avoidance
  
  functions and provides information that will enable
  
  the identification of appropriate functional
  
  requirements, performance specifications, objective
  
  test procedures, and initial system effectiveness
  
  benchmarks. The framework incorporates crash
  
  statistics about the driving environment, contributing
  
  and causal factors, and kinematic information. In
  
  addition, time-to-collision equations for each precrash
  
  scenario are derived to identify key variables
  
  that must be measured to recognize and assess the
  
  crash threat of driving conflicts. Crash statistics are
  
  obtained from national crash databases including the
  
  2004-2008 General Estimates System, the National
  
  Motor Vehicle Crash Causation Survey, and the
  
  Event Data Recorder database. A set of ten pre-crash
  
  scenarios are identified as a priority for the
  
  development of V2V-based safety applications.
  
  These priority scenarios are arranged into five crash
  
  avoidance packages that consist of rear-end, lane
  
  change, opposite direction, junction crossing, and left
  
  turn across path/opposite direction crash
  
  countermeasures. This paper delineates the priority
  
  pre-crash scenarios and maps them to V2V-based
  
  safety applications under development.
