Abstract
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 towaway crash data from three US states, and accident compensation claims from Finland. New methods of vehicle aggressivity rating were also proposed and tested.
