Ensuring improved traffic safety in road transport is one of the EU's priorities and, at the same time, an opportunity to gain competitive advantages of the European automotive industry and the entire economy. In the European Union’s Horizon 2020 framework programme, the European Commission has supported the Open Access virtual testing protocols for enhanced road-users safety (VIRTUAL) project with a little less than seven million Euros, in which researchers from the Chair of Modelling in Engineering Science and Medicine from the Faculty of Mechanical Engineering, with 14 other partners from nine European countries, developed simulation tools to enhance road-users safety. The OpenVT platform will allow virtual testing of security systems for pedestrians, cyclists, car users and public transport.

Project manager at the Faculty of Mechanical Engineering, dr. Simon Krašna, will work with his colleagues, industrial, and research partners, such as Volvo and Siemens, in a 4-year long project to develop human body models and procedures for testing safety systems for passenger protection in cars, public transport, as well as the most exposed groups of road users (pedestrians, cyclists). The aim of the project is to establish an open virtual vehicle testing platform for vehicle and road users.

Dr. Simon Krašna explained the following about cooperation in the VIRTUAL project:

“Road vehicles must meet the stringent safety standards. Vehicle manufacturers and their suppliers are making considerable efforts in developing active and passive safety systems built into vehicles that contribute  in preventing human injuries in traffic accidents. In doing so, performance of safety systems is valued and improved by means of test collisions, which are both demanding and costly.

In the last decade, the progress in simulation methods, computational capabilities and knowledge of human biomechanics under conditions of collision has enabled the response of the human body to the collision to be virtually analysed by computer simulations. With virtual testing, we can effectively analyse a wide range of accidental situations, assess the potential for injuries of people, and evaluate operation of safety systems to protect road users.

A major challenge in the development of human body models that replace test dummies in virtual testing is an active human response in vehicle autonomous collision avoidance manoeuvres or at low speed collisions. Along with the development of autonomous vehicles, which tends to be a gradual long term process, changes in the way passengers sit in vehicles are also expected. On the other hand, trend of urbanization and sustainable modes of transport leads to increased exposure of pedestrians, cyclists and passengers in public transport.

Numerical models of the human body are already included in the evaluation of pedestrian protection in vehicle collisions according to EuroNCAP. This confirms correctness of the orientation towards virtual safety testing for other groups of road users, and finally to standardisation of virtual testing protocols."
