This chapter investigates TA scenarios and performs simulations. In order to start the simulations, several preparatory steps were made. At first, scenarios had to be defined. As capabilities of future AVs are difficult to foresee and as the problem has several dimensions, it has been decided to use service definitions (i.e. the kind of possible infrastructure influences) as the main criterion for clustering the dimensions. Five services have been proposed and converted into five scenarios. In order to perform baseline simulations of the five scenarios, vehicle models had to be chosen and even newly developed, so that simulation of AVs and the TOC became possible. The models needed to be parametrized according to estimations of future traffic shares, future number of TOR, TOC, and MRM. This chapter highlights the measured effects in one of the studied scenarios. It also explains how simulations get more sophisticated and realistic by using the iTETRIS-integrated platform for traffic simulation, communication, and TM. Furthermore, the plans for performing real-world feasibility assessments including V2X message set definitions have been introduced, closing this first report.
