Eclipse OpenPASS

Eclipse OpenPASS is an open-source simulation framework for modeling, executing, and evaluating traffic and automated driving scenarios for Research and Development (R&D) in automated and connected vehicle systems (simulation / automotive software).

  • Framework for traffic and automated driving simulation (simulation / automotive)
  • Scenario-based evaluation of automated driving functions and assistance systems (testing and validation)
  • Modular and extensible architecture for simulation components and models (software framework)
  • Support for multi-agent traffic environments with various road users and behaviors (mobility simulation)
  • Tooling for configuring, running, and analyzing simulation experiments (simulation tooling / analytics)

More About Eclipse OpenPass

Eclipse OpenPASS is an open-source simulation framework from the Eclipse Foundation focused on virtual testing and evaluation of automated and connected driving functions (simulation / automotive). The project targets the problem space of assessing advanced driver assistance systems (ADAS) and automated driving systems (ADS) in reproducible, parameterizable traffic scenarios. It addresses the need for structured simulation environments where road infrastructure, traffic participants, and vehicle automation functions can be combined into configurable experiments for research, development, and safety assessment.

The framework provides capabilities for scenario-based simulation of road traffic (simulation tooling), where multiple agents such as passenger vehicles and other road users interact in a shared environment. Users can define scenarios, behavior models, and sensor or automation functions as components that operate during simulation runs. OpenPASS employs a modular architecture (software framework) that separates concerns such as world representation, agent behavior, vehicle dynamics, and function logic, enabling replacement or extension of individual modules without altering the entire system.

OpenPASS is designed to be extensible for enterprise and institutional environments that require integration with existing toolchains (systems integration). Its component-based design allows organizations to plug in proprietary or domain-specific models, such as custom controllers, perception models, or traffic behavior modules, while using the common simulation core, configuration formats, and execution engine. This supports workflows in which simulation is part of a broader Verification and Validation (V&V) process for automated driving functions.

The project exposes configuration and scenario description mechanisms (configuration management) that let users define experiments, parameter sets, and variant runs. This enables systematic variation of conditions, such as traffic density, weather approximations, or driver behavior parameters, depending on the models that users integrate. The framework also supports collection of outputs and KPIs from simulation runs (analytics / evaluation), which can be consumed by external analysis tools or reporting pipelines for safety assessment and performance benchmarking.

Within enterprise contexts, Eclipse OpenPASS is applicable as a component in virtual testing environments for Advanced Driver Assistance System (ADAS) and Autonomous Defense System (ADS) (quality assurance / safety validation). It can be used by automotive OEMs, suppliers, research institutions, and engineering service providers that need a configurable, transparent simulation base maintained under Eclipse Foundation governance (open-source governance). In a technical directory or taxonomy, Eclipse OpenPASS fits into categories such as automotive simulation platforms, virtual validation frameworks for automated driving, and model-based testing tools for intelligent transport systems.
