Pedestrian Impact

The Pedestrian Impact tool facilitates the post-processing of pedestrian analysis.

This tool uses time-history and result files as input and conforms to the pedestrian safety regulations GTR, EuroNCAP, and Homologation. Pedestrian Impact automates the process with minimal input, therefore reducing the deck generation lead time with less human error.

In HyperView or HyperGraph, from the Safety ribbon > Impacts tool group, click the Pedestrian tool to invoke Ped Pro Post browser tab.

Note: Pedestrian Impact is not supported for the Vehicle Safety Tools + HyperView - MultiCore preference.
