Goal
The purpose of this research program is to investigate the problems of vehicle aggressivity and compatibility in multi-vehicle crashes. The near term goal is to identify and demonstrate the extent of the problem of incompatible vehicles in vehicle-to-vehicle collisions. The objective is to identify and characterize compatible vehicle designs with the expectation that improved vehicle compatibility will result in large reductions in crash related injuries. Specifically, this program seeks to identify those vehicle structural categories, vehicle models, or vehicle design characteristics which are aggressive based upon crash statistics and crash test data. Light truck and van collisions with cars are one specific, but growing, aspect of this larger problem.
