ViVAVirtual Vehicle Safety Assessment: Open Source
Digital Human Body Models and Crash Testing
Duration: 3 years, started 1 Jan 2014
Budget: 550 000 Euros
Financed by: Swedish Governmental
Agency for Innovation Systems
(VINNOVA)
ViVA: aim and objectives
Aim
To reduce transport gender inequality in traffic safety assessment by focusing on
safety for male and female vehicle occupants and develop an open source
human body model for crash simulation
The objectives of the ViVA project are to:
• Create an open source virtual Human Body Model (HBM) platform of a
prototype of an average female.
• Propose a virtual test method protocol for Virtual Testing suitable for different
seated postures and genders will be developed.
• Demonstrate the virtual test method and HBM for females in rear impacts
tests.
