SAFER Thursday seminar March 11th: Virtual models for human body protection

The SAFER Thursday seminar week 10 is hosted by Jolyon Carroll, SAFER’s Research area director for Human Body Protection. The topic this week is ‘virtual models for human body protection’.

The project VIRTUAL: Open access virtual testing protocols for enhanced road user safety
Speaker: Astrid Linder, Prof, PhD, MSc, Research Director Traffic Safety, VTI –  Swedish National Road and Transport Research Institute.

VIRTUAL has been running for nearly 3 years, started June 2018, has 15 European partners, and is funded with 7 Million Euros by the European Commission. The overall objective of VIRTUAL is to improve the safety of urban road users by providing procedures and open access tools to assess the benefit of novel safety systems. The goal is to establish a European based global hub for Open Source Virtual Testing freely accessible on the internet and to demonstrate its success in traffic safety. Open Source Human Body Models (OS-HBMs) of both men and women are being developed in a format that is scalable to represent all different ages and sizes for car occupants, vulnerable road users (VRU), and users of public transport.

This presentation describes the OpenVT platform and its content, the concepts of the VIVA+ models used for seated occupants, cyclists and pedestrians. In addition, the findings regarding balancing strategies for standing occupants in public transport are described.

Rapid posturing and simulation of diverse road user activities using the Digital Human Modelling tool IPS IMMA
Speakers: Erik Brolin, PhD,  Senior lecturer in Product Design Engineering, School of Engineering Science, University of Skövde and Dan Högberg, PhD, Professor in Integrated Product Development, School of Engineering Science, University of Skövde.

Human Body Modelling is frequently used for vehicle safety analyses. However, computationally such simulations typically takes a long time, which in turn can lead to a situation where the simulations have a reduced level of consideration of diversity regarding both anthropometry and road user activities. Digital Human Modelling (DHM) systems use less advanced virtual human models, so called digital manikins, but offers the possibility to do rapid simulations while considering anthropometric diversity by simulating with a family of manikins. The presentation will demonstrate the possibilities of the Swedish DHM system IPS IMMA regarding definition and representation of anthropometry, and posturing and simulation of diverse road user activities.

The presentation will also discuss future research topics regarding possibilities of using joint centre, landmark and body shape data from DHM systems such as IPS IMMA to posture advanced Human Body Models for more detailed safety analyses.

Please observe that attendance to  SAFER seminars requires a registration. All SAFER Thursday seminars will be held exclusively online, via Microsoft Teams, until further notice. Link will be sent by email when registration ends, one day before the seminar.
