A Desktop Model for Computing Acceleration Severity Index (ASI) for Rigid Barriers as A Function of Impact Configuration

Burbridge, A, Troutbeck, R


ARSC conference 2017

Acceleration Severity Index (ASI) is a vehicle occupant risk indicator measured during homologation of road safety barriers. Efforts to correlate occupant injury risk with ASI exist (Li et al., 2015; Roque & Cardoso, 2013; Shojaati, 2003). Hence there is value in exploring how ASI might vary with impact configuration (impacting vehicle mass, speed and angle). This paper describes the development and testing of a desktop model for predicting ASI in impacts with rigid barriers as a function of impact configuration. The efficacy of the model is tested against published data.
