Car-to-car communication is besides autonomous driving and e-mobility one of today’s most important topics in automotive research. Currently, two transmission technologies are available for safety-critical applications in vehicle-to-vehicle communication: WIFI-based ITS-G5 and cellular-based LTE-V2X [1]. In this article ITS-G5 is used as the primary transmission technology to support safety-critical applications within a wide range of traffic situations by exchanging information between individual vehicles. The resources of the LTE-V2X communication will be used to support the WIFI-based communication in case a reliable transmission via ITS-G5 is not or only partially possible. In a simulation environment several test series were developed to investigate different traffic scenarios, use cases and equipment rates for both transmission technologies. This will show how often and in which situations the resources of LTE-V2X are used.
