Abstract: An example method for extracting traffic scenarios from vehicle sensor data is disclosed. The example method includes acquiring vehicle data generated by one or more sensors coupled to a vehicle. The vehicle data is at least partially indicative of the surroundings of the vehicle during a particular time frame. The vehicle data is analyzed to identify objects in the surroundings of the vehicle and to determine the motion of the vehicle relative to the surroundings during the particular time frame. A plurality of events are defined, each indicative of a relationship between the vehicle and the objects. A scenario is defined as a particular combination of the events. Portions of the vehicle data in which the combination of elements occurs during a time interval are identified, and at least some of the identified data is extracted to a predefined data structure to create an extracted scenario.
