Traffic problems have mainly resulted from an increase in mobility over the last decades involving an increase in traffic congestion and degradation of environmental conditions. The employment of new systems - namely, Intelligent Transport Systems (ITS) is being considered for their mitigation (1,2). ITS offer a high number of applications providing different types of support to the user: usually the driver or the traveler. These may range from "simple" solutions dedicated to comfort (e.g. parking aid, e-toll) or information services (e.g. navigation, Variable Message Signs) to more complex ones such as Advanced Driver Assistance Systems (ADAS). One may distinguish pre-crash ADAS (e.g. collision warning, lane warning), post-crash ADAS (e-call) and fully automatic driving systems like Automated Highway Systems (AHS). The complexity is characterized through the maturity level and market distribution.
