Road traffic is highly complex and difficult to describe. And yet it is absolutely essential that we manage to present it in a compact form in meaningful test scenarios. Only in this way can we succeed in bringing highly automated driving functions to series production readiness in the foreseeable future.
The test scenarios themselves can be generated either logically, i.e. from abstract considerations, or data-driven, i.e. from analyses of the traffic situation. Or a combination of these two possible approaches. And it is precisely for this purpose that it is important that we use as much information and knowledge as possible to generate test scenarios that are as relevant as possible: We have to merge different databases, such as data from traffic observations and accident records. You can read how this can be done here: “With accident and traffic observation data to the optimal test scenario”.
