Designing advanced driver assisted systems in a risk-based process

This chapter discusses the issue of risk-based design (RBD) in modern technology perspective. RBD is a well-formalized and consolidated methodology implemented in design process. Modern technology and the extensive use of automation require the consideration for very relevant aspects that are neglected in risk analysis; i.e. the temporal and logical relationship between events, especially associated with human factors.

The chapter shows how it is possible to integrate in a classical RBD flowchart the time dimension, by developing a quasi-static approach. The methodology makes use of classical methods and some innovative features for building sequences of events that enable us to consider the human–machine interaction (HMI) in a more logical and functional relationship that the simple event tree standard method.

The chapter presents a case study that shows the implementation of the RBD methodology for the case of an advanced driver assistance systems (ADAS) associated with a traffic light (TL) scenario.
