Road restraint systems - Validation and verification process for the use of virtual testing in crash testing against vehicle restraint system

This technical specification outlines a comprehensive methodology for the validation and confirmation processes involved in testing vehicle separation systems through computer simulations. The document establishes rigorous criteria for evaluating the accuracy and reliability of virtual models used to assess crashworthiness and performance of road isolation barriers. It defines essential parameters for input data, boundary conditions, and simulation scenarios to ensure consistent and reproducible results across different testing environments. The approach facilitates the correlation between simulated outcomes and physical test data, thereby supporting the development and improvement of safety infrastructure without the immediate need for full-scale field experiments. By detailing specific analytical techniques and acceptance thresholds, this guidance aids engineers and regulatory bodies in verifying that virtual testing procedures meet high standards of engineering integrity. The framework is designed to enhance confidence in simulation-based assessments for road safety systems, promoting uniform application of testing protocols throughout the industry.
