Road vehicles — Advanced automatic collision notification (AACN) systems — Methodology for creating and validating algorithms for injury level prediction

Scope

This document outlines methodologies for creating and evaluating AACN algorithms, using suitable parameters, to predict the level of injury sustained by road users in a collision.
The injury prediction is used to facilitate emergency response after a collision occurs.
The methodology is based on onboard vehicle data and occupant-related information and applies to vehicle occupants and vulnerable road users.
This document is applicable to road vehicles having provisions for measuring and communicating crash related data.
This document provides neither a particular AACN injury level prediction algorithm, nor information on how to use the estimated probability of injury to decide on further suitable actions (rescue, medical, etc.).
Data format for sending vehicle information and communication protocol between the vehicle and the public service answering point (PSAP) is outside the scope of this document.
