  • 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.
