    In the last decades, road traffic significantly increased in many regions. As part of sustainable urban areas, the improvement of safety as well as the optimization of traffic flow are important challenges for road mobility. The new mobile communications standard 5G, which is currently being rolled out, is being promoted with a variety of improvements that also address the transport sector. As one component of a smart city approach, a proposed solution to increase road traffic safety and to optimize the traffic flow by means of using 5G is currently being developed and deployed in the city of Aalen, Germany, as part of the "5G-trAAffic" project.

    Road traffic significantly increased in the last decades. The avoidance of accidents and the continuity of traffic flow are significant challenges for road mobility. In this paper, a real-time Internet of Things (IoT) architecture is presented for these current road traffic challenges. The presented architecture takes advantage of the emerging 5G mobile technology and relies on infrastructure components so that the presented architecture can be integrated into city infrastructure to become smarter and provide benefits to citizens. A collision warning service is being implemented to warn road users of imminent collisions. The parallel traffic flow optimization will also enable the prioritization of highlighted traffic partici-pants, such as emergency vehicles. By prioritizing pedestrians, bicycles, e-bikes and buses, for example, it will also be possible to achieve specific traffic and climate policy goals. An according smartphone app allows the resulting advantages to be used in the short term. Furthermore, additional actuators such as displays and signal transmitters will integrate all road users, regardless of the specific app usage. By using 5G, these components will also be implemented quickly, flexibly and reliably as infrastructure IoT devices. The paper concludes with a presentation of a research project in which these solutions are currently being implemented.
