European countries face great challenges because the demographic structure in the EU is changing rapidly. Meanwhile, the mobility needs of the elderly are also changing. Maintaining a driver’s licence is an important issue of independence today, both for males and females. Also technological developments like the introduction of e-bikes enables access to other means of transport. While accident data show a decreasing number of fatalities and serious injuries on EU roads, recent data from the ERSO show an increasing proportion of elderly in the fatality statistics. This trend is a serious threat to the achievements of recent decades and poses a challenge that must be addressed to meet goals set for further reduction of road fatalities. Furthermore, there is an increasing rate of obesity in EU populations, which introduces changes in injury patterns and risks. The SENIORS project focuses on the protection of elderly and obese road users also by transferring nowadays younger generations’ safety standards. The overall goal is to improve the passive vehicle safety by adopting test tools, test procedures and test assessments from legislation and Euro NCAP. Hereby, various computer simulations and experimental testing will be used to ensure the scientific background for decisions.
