Cameron, Pg. 1 EMPIRICAL COMPARISON OF VEHICLE AGGRESSIVITY RATING SYSTEMS

Paper Number 2001-S7-O-133 This paper describes an empirical comparison of seven vehicle aggressivity rating methods in order to identify the most satisfactory vehicle aggressivity ‘rating ’ system. Vehicles were distinguished by make and model, and the aggressivity of each model was estimated from data on real two-vehicle crashes. For comparison purposes, two common crash databases were used for estimation of ratings by each method: Police-reported tow-away crash data from three US states, and accident compensation claims from Finland. New methods of vehicle aggressivity rating were also proposed and tested
