Pedestrian Impact - HyperView

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 user input, therefore reducing the deck generation lead time with less human error.

Pedestrian Post is only available under the Vehicle Safety Tools preference file profile.
Restriction: This tool is not supported for the Vehicle Safety Tools + Upfront Data Loader preference file profile.
