Description
Flexibility of a road safety barrier is a measure of the propensity of the barrier to deflect during impact. Acceleration Severity Index (ASI) is a vehicle occupant severity indicator measured during homologation of road safety barriers. Published literature suggests that ASI may vary with impact configuration (impacting vehicle mass, speed and angle) and barrier flexibility. Published literature also suggests that ASI may be a vector to occupant injury outcomes. The development of a model for predicting ASI for tracking impacts with road safety barriers as a function of impact configuration and flexibility is presented. The model is used to illustrate how ASI is predicted to vary as a function of impact configuration.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
