With the aim of facilitating a comparative functional analysis of driving assistance systems and infrastructure measures for traffic safety, this paper studies the underlying concepts of safe road design, and derives a general set of traffic safety principles. Road categorisation is studied as an important parameter for both road design and route selection that are optimised from a traffic safety perspective, and an extended road categorisation is proposed. Finally a systematic overview of infrastructure measures is provided, as a basis for a future comparative functional analysis. For the covering abstract see ITRD E138952.
