Road Traffic Burden 2/2

WHO expects that by 2020 Road Traffic is 3rd largest contributor to burden

of disease and injury

=> No action will increase burden by 60 % from today

Conclusion

• The design for cars to meet real life safety requires basic research

• A fundamental part of this must be Accident Research, which helps to

understand Accident Causation and Injury Causation/Mechanism

• During design, advanced tools like THUMS can help increasing protection

potential beyond traditional borders

• It is important re-confirm the effect after each improvement cycle
