Scenario-based development and test processes are a promising approach for\nverifying and validating automated driving functions. For this purpose,\nscenarios have to be generated during the development process in a traceable\nmanner. In early development stages, the operating scenarios of the item to be\ndeveloped are usually described in an abstract, linguistic way.Within the scope\nof a simulation-assisted test process, these linguistically described scenarios\nhave to be transformed into a state space representation and converted into\ndata formats which can be used with the respective simulation environment.\nCurrently, this step of detailing scenarios takes a considerable manual effort.\nFurthermore, a standardized interpretation of the linguistically described\nscenarios and a consistent transformation into the data formats are not\nguaranteed due to multiple authors as well as many constraints between the\nscenario parameters. In this paper, the authors present an approach to\nautomatically detail a keyword-based scenario description for execution in a\nsimulation environment and provide a basis for test case generation. As a first\nstep, the keyword-based description is transformed into a parameter space\nrepresentation. At the same time, constraints regarding the selection and\ncombination of parameter values are documented for the following process steps\n(e. g. evolutionary or stochastic test methods). As a second step, the\nparameter space representation is converted into data formats required by the\nsimulation environment. As an example, the authors use scenarios on German\nfreeways and convert them into the data formats OpenDRIVE (description of the\nroad) and OpenSCENARIO (description of traffic participants and environmental\nconditions) for execution in the simulation environment Virtual Test Drive.\n
