Traffic simulation that takes into account also the V2X communication possibilities has become a promising research topic. Researchers of the Autonomous Systems National Laboratory (ARNL) aim to support the research community working on this topic with the development of a SUMO, Veins, INET and OMNeT++ based co-simulation platform. The platform is intended to be used in connected and autonomous vehicle (CAV) related tests and measurements. The platform can simulate V2X wireless communication in great detail. For instance, it models various aspects of signal propagation, interferences and shielding, as well as of electromagnetic noises. The platform supports 802.11p and 5G communication technologies. Some functions of the co-simulation platform have already been successfully demonstrated to an expert audience.
A signal attenuation simulator has also been implemented. It is based on the Unity 3D video game engine. The simulator computes communication signal attenuations that arise due to signal transmission through 3D objects. A technical manual has been compiled for this simulator. It is available from here.
