Positioning of OpenScenario in V-Model


  • OpenSCENARIO defines a file format for the description of the dynamic content of driving and traffic simulators
  • OpenSCENARIO files are defined by an XML schema (*.xosc)
  • The current version (0.9.1 released 2017) of OpenSCENARIO is developed, owned and published by VIRES Simulationstechnologie GmbH. The specification is transferred to ASAM to become a public standard (first release expected in 2019)
  • Application areas are
    • Description of vehicle maneuvers in a storyboard
    • Driving simulation
    • Traffic simulation
  • While OpenDRIVE (Road Network) and OpenCRG (Road Surface) describe the static content of driving simulation environments, OpenSCENARIO describes the dynamic content
  • OpenSCENARIO is a key element in PEGASUS project, which defined various initial use cases
  • The ASAM OpenSCENARIO Concept project, starting in January 2020, aims to evaluate and to conceptionally specify feature requests for the further development of ASAM OpenSCENARIO

Relevance and Benefit for MBSE

  • Scenario based virtual verification, testing and validation of driver assistance systems and highly automated vehicles
  • Basis technology for scenario modelling and to the exchange of scenario models between development partners
  • The benefits of using OpenSCENARIO files are
    • open file format
    • tool-independent description of specifications for time-variant behavior of elements in a simulation run
    • possibility to describe very complex traffic situations from highway to urban areas
    • description of scenarios on a logical and a concrete layer of abstraction
    • enabling of reusability using parameterization and catalog-based scenarios
    • easy validating, editing, importing and exporting of the XML file by simulation tools and content editors

Risks and Impediments

  • New and upcoming standard
  • Actual less tool & vendor support
  • Missing interoperability between modelling tools
  • Small user community – but growing
  • No reference implementation for driver models
  • Version 2.x is work in progress – unclear compatibility between 0.x und 2.x of the XML schema
