VSimRTI was developed for simulations where one single simulator is not sufficient (e.g. V2X simulations that need vehicle traffic and communication simulation). VSimRTI makes the preparation and execution of such simulations as easy as possible for the users. Therefore, a lightweight framework for simulator integration was created. In contrast to existing fixed simulator couplings, the VSimRTI simulation infrastructure allows the easy integration and exchange of simulators. Thus, the high flexibility of VSimRTI enables the coupling of the most appropriate simulators for a realistic presentation of vehicle traffic, emissions, wireless communication, and the execution of applications.

Depending on the specific requirements of a simulation scenario, the most relevant simulators can be used. All management tasks, such as synchronization, interaction and lifecycle management are handled completely by VSimRTI. Several optimization techniques, such as optimistic synchronization, enable high performance simulations. Special V2X features, e.g. traffic lights, roadside stations, and both CAM and DENM message types, are supported by VSimRTI. Moreover, various configuration options and enhanced user and developer documentation assure maximum usability.For immediate use, a set of simulators is already coupled with VSimRTI. For example, the traffic simulators VISSIM and SUMO, the communication simulators JiST/SWANS and OMNeT++, the application simulator VSimRTI_App, and several visualization and analysis tools are prepared for VSimRTI.

VSimRTI couples different simulators (e.g. for vehicular traffic, wireless network communication, and application simulation) and, thus, enables the simulation of the various aspects of (future) intelligent transportation systems.
