The aim of the WISE-ACT Working Group 5 (WG5) is to shed light on the methods and results that have appeared in the AV domain, investigating simulation experiments and analyses, while building on those to develop and assess new scenarios. This is done for example by employing or developing novel simulation methods and tools, tailored to address the ever-growing complexity of future transport systems. A special emphasis is also on the criteria and indicators that are used to evaluate the results and that are of pivotal importance for well-informed decision-making. This approach was favoured against others such as field test analyses due to the relatively low number of prototype vehicles currently on public roads and on the secrecy that automakers legitimately keep on the capabilities of said prototypes. Simulation studies, on the other hand, have extensively studied, the state of the art currently including a wide range of modelling tools. In particular, the key tasks of WISE-ACT WG5 have been identified in the WISE-ACT MoU (Memorandum of Understanding) as:
