Eclipse Mosaic

Eclipse Mosaic is an open-source simulation framework for testing and evaluating connected, automated, and electric mobility systems across combined traffic, communication, and backend environments (simulation and modeling).

• Co-simulation of traffic dynamics, communication networks, and backend systems for intelligent transportation scenarios (simulation and modeling).
• Support for connected, cooperative, and automated mobility scenarios, including Vehicle-to-Everything (V2X) communications (intelligent transportation systems).
• Modular architecture that integrates heterogeneous simulators via defined interfaces and coupling mechanisms (integration framework).
• Configuration and orchestration of large-scale experiments for Research and Development (R&D) of mobility services and infrastructure (R&D tooling).
• Support for scenario definition, reproducible experiments, and evaluation of concepts for future mobility and smart city use cases (urban mobility planning).

More About Eclipse Mosaic

Eclipse Mosaic is a simulation framework for connected, automated, and electric mobility that focuses on combined and coordinated simulation of traffic, communication, and backend systems (simulation and modeling). It targets the problem space where intelligent transportation systems depend on the interaction between vehicles, roadside infrastructure, communication networks, and cloud or backend services. The framework provides a basis to analyze behavior, performance, and constraints of new mobility concepts before deployment in real environments.

The project uses a co-simulation approach that couples specialized simulators through a modular integration layer (integration framework). This allows traffic simulators, network simulators, and backend or cloud service simulators to exchange data during runtime under a unified time management and scenario control. Eclipse Mosaic provides components for scenario configuration, experiment management, and data collection, which support repeatable experiments over a wide range of mobility and communication conditions.

Eclipse Mosaic addresses connected and cooperative mobility scenarios, including V2X communication (V2X) and automated driving use cases (intelligent transportation systems). By modeling both road traffic behavior and wireless communication, the framework enables study of latency, reliability, and load effects on cooperative driving functions, traffic management strategies, and smart infrastructure services. Backend and cloud components in the co-simulation allow evaluation of architectures where vehicles interact with services such as fleet management, traffic control centers, or mobility platforms.

In enterprise and institutional environments, Eclipse Mosaic is used as a tool for R&D, system validation, and feasibility analysis of concepts for future mobility (R&D tooling). Automotive manufacturers, suppliers, traffic infrastructure operators, and research institutions can construct scenarios that represent urban, highway, or mixed environments, define communication technologies and protocols, and assess how applications behave under these modeled conditions. The framework supports analysis of both application-level behavior and underlying system constraints such as bandwidth, message scheduling, or processing delays.

Architecturally, Eclipse Mosaic is positioned as a co-simulation coordination layer that connects domain-specific simulators for road traffic, communication networks, and backend services (simulation orchestration). It exposes defined coupling interfaces and configuration models so that organizations can integrate preferred traffic or network simulators where compatible. This extensibility supports heterogeneous environments and allows alignment with existing tooling landscapes. In a directory or taxonomy context, Eclipse Mosaic fits into categories for intelligent transportation systems simulation, V2X and networked mobility testing, and co-simulation frameworks for cyber-physical and mobility systems.
