AVAILABLE ACCOMPANYING DOCUMENTATION

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

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

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
