In Criteria for age based design of active vehicle safety systems the recent results of the research project Evaluation of active vehicle safety systems and components in regard to their safety impact on elderly car drivers are presented. The project is funded by the Federal Highway Research Institute (BASt). The project aims to answer the question whether Advanced Driver Assistance Systems (ADAS) are able to support elderly drivers to stay mobile and, if so, how they need to be designed to do so. The aim of the project is to retrospectively develop a list of criteria which shall help to develop future age-based designs of driver assistance systems. Therefore an extensive market analysis was carried out at first. The market analysis contained a literature research, a survey with 70 elderly people and expert interviews. In the second phase test drives combined with special workload assessments were conducted.
