For Improving Safety on Roads Outside Built-up Areas with Cooperative/Self-sufficient Advanced Driver Assistance Systems

The number of accidents with serious personal injuries, fatalities and injured persons on German roads outside built-up areas has been falling since 1970: due not least to improvements in vehicle safety, in particular from self-sufficient Advanced Driver Assistance Systems (ADAS). Engineers hope for ADAS that help to avoid or reduce severe accidents. But how and where do relevant accidents occur? What do they have in common and what information is required in order to indicate imminent danger? To answer these questions, accidents on roads outside built-up areas were examined, and the general requirements to be met by suitable cooperative systems were identified. It was revealed that, due to the high level of investment these systems require, both in terms of technical input and finance, there are really only a few applications for which it makes sense to use infrastructure-based driver assistance systems.
