Influence of vibrations on mental human performance for driving safety in heavy vehicles

This manuscript describes an experimental study aimed at determining the existence and the correlation between physiological human performance within the field of heavy goods vehicles and absorbed whole-body vibrations. The reaction times obtained have been compared to those published in open literature and interesting discrepancies and findings have been obtained; the discrepancies are due to the fact that a quasi mental reaction time is measured through a non invasive computerized human interface, which has been adopted for minimizing the participation of external factors. The experiments, carried out in a controlled environment through accurately described conditions, are, verifiable for future comparisons; relevant conclusions are finally extracted.
