Abstract: A computer-implemented method and system for classifying a predefined traffic situation comprised by a data record of environment data of a motor vehicle, with an application of a directed graph to the first data record. Nodes of the directed graph segment the first data record in each case into at least one segment of a movement behavior of the ego vehicle and/or the fellow vehicle relative to a vehicle environment according to a first condition satisfied in a time interval comprising edges of the directed graph symbolizing links between the respective nodes. The predefined traffic situation is classified if all of the specified segments meet a second condition of the predefined traffic situation. A class is outputted representing the predefined traffic situation and/or a respective start and end time of the second data record comprising a segment representing the predefined traffic situation.

Abstract: A method for creating a three-dimensional simulation environment, including: providing a basic library containing three-dimensional virtual objects; detecting the input of a geographic region; obtaining characteristic information, which characterizes the features of different areas; deriving additional information for the various areas of the geographic region on the basis of the characteristic information, land use information being derived as additional information if the characteristic information does not comprise any land use information; ascertaining the objects from the basic library which occur in the geographic region, and storing these objects in a regional library; dividing the geographic region into sectors of the same land use on the basis of the land use information; ascertaining, for each sector, the objects from the regional library which match the land use of this sector; and filling each sector with a selection of objects, based on its land use.
