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.
