With Eclipse MOSAIC, Fraunhofer FOKUS presents a simulation framework based on VSimRTI (Vehicle-2-X Simulation Runtime Infrastructure). The TU Berlin and the Daimler Center for Automotive IT Innovations (DCAITI) had worked on VSimRTI in the past 12 years and it was with around 600 Partners used to test mobility services and traffic scenarios.

Basic version is open source The project operators are now making the source code of parts of the framework available on GitHub. This release is in the context of the imminent EclipseCon dated 19. to 22. October 2020 this time online.

The GitHub repository includes the traffic simulator Eclipse SUMO and simulators for Events and the environment a series of simulators for communication and an output generator for evaluation and visualization. The project relies on Maven and has a modular structure. The modules are divided into three categories: an interface for the runtime infrastructure (RTI) and its implementation as well as the core libraries for mathematical functions, spatial data, routes, communication models and data exchange. The third module area are the so-called MOSAIC Ambassadors, who ensure the integration of the various simulators and their integration within the framework.

Mobility scenarios: Modeling of hybrid roads Eclipse MOSAIC is to integrate various aspects such as traffic density, battery charging of electric cars and communication between different road users via a central cloud and make them accessible as a higher-level system. Users can obviously choose which details they would like to examine more closely: According to the provider, the options range from rough mobility scenarios to city traffic to specific driving maneuvers of individual road users the integrated simulators can be individually exchanged, all simulators obviously take into account the information of the others and all simulators should run synchronously. The framework offers tools for evaluating and visualizing the results. According to the provider, this functionality is also included in the open source package. Eclipse MOSAIC completed the practical test as part of an EU project called INFRAMIX, in which the Austrian operator of motorway infrastructure ASFINAG, Siemens, BMW and operators of Spanish and German motorways were involved. The simulation environment should be used for digitization and communication in the transition area between conventional and autonomous driving and enable safe mixed traffic through targeted modeling and planning. Networked, automated mobility should reduce the costly expansion with variable message signs, announced the Fraunhofer developers in their blog at the end of the test phase at INFRAMIX in the summer.
