You can also read more about OpenSCENARIO format on the ASAM website. Other content, such as the description of the ego vehicle, driver appearance, pedestrians, traffic and environment conditions, is included in the standard as well. derived from a recorded driving maneuver). performing a lane change) or on trajectories (e.g. The description of a maneuver may be based on driver actions (e.g. The primary use-case of OpenSCENARIO is to describe complex, synchronized maneuvers that involve multiple entities like vehicles, pedestrians and other traffic participants. GeoReference data must either be inserted into the header before opening the file in RoadRunner or predetermined elsewhere within RoadRunner.Open Scenario Editor is a simple ASAM OpenSCENARIO (*.xosc) editor based on Environment Simulator Minimalistic (esmini).ĪSAM OpenSCENARIO defines a file format for the description of the dynamic content of driving and traffic simulators. OpenDrive 1.6: Requires header to include a “geoReference”.Using translated files with third-party tools:ĭepending on how your chosen simulator/application interprets ASAM OpenSCENARIO v1.1 and OpenDRIVE v1.6 files, you may be required to make minor modifications to view the scenario as intended. Future iterations of the conversion toolchain will replace the present single point intersection implementation with a smooth and seamless transition between the roads at the intersection. To improve the visual appearance of these junctions, we are in the process of adding more intricate geometric details. At present, intersections (T-junctions, cross-junctions, Y-junctions) are geometrically treated as a single point where all connecting roads meet. Junctions are easier to represent once the roads have been translated into a suitable OpenDRIVE v1.6 format. Intersection Representation: The definition of junctions in Level-2 SDL takes a declarative form and must be translated into a set of concrete geometries for ASAM OpenDRIVE v1.6.These changes allow us to define lane change manoeuvres in a consistent, position independent manner, as a relative lane change action. For left-handed traffic, all lanes are positively numbered, while for right-handed traffic they are negatively numbered. Hence, a bidirectional road, which is typically represented as a single road with lanes on either side, is transformed into two distinct roads with opposing driving directions and road start and end points. Road Representation: Specific transformations for roads are needed during the transition from SDL to ASAM OpenSCENARIO v1.1 and OpenDRIVE v1.6 to treat lane manoeuvres uniformly regardless of the lane/road position of the car, or direction of traffic.Additionally, we also provide a list (likely incomplete) of common tools and respective steps required for successful scenario import. To help users of SafetyPool TM understand our translations better, below we describe a few elements of our translation and the motivation behind the translation choices made. Further, translation choices (how to represent our SDL elements in OpenX) have been made to ensure that the semantic meaning of the scenarios are, as far as possible, retained. Hence, minor modifications might be necessary to meet the requirements of your choice of tool. This is because different simulators can have differing requirements, in addition to those in the defined schema. However, given the multitude of available off-the-shelf simulators, we understand that additional tooling may be necessary to make our scenarios compatible. The translated scenario specifications comply with their respective schemas for ASAM OpenSCENARIO v1.1 and OpenDRIVE v1.6. ![]() ![]() ![]() Our translation algorithm keeps improving with the help of feedback from our users. Our translation is designed to ensure that the meaning of the scenarios in Safety Pool is well represented. Since the languages do not share the same syntactic structures, the translation process is a semantic one. Translation between Level-2 SDL and these standards is non-trivial. This ensures that our scenarios are useful to a wide variety of stakeholders, as dictated by our values. To make scenarios on SafetyPool TM accessible and usable with off-the-shelf simulation platforms, scenarios in our Level-2 Scenario Description Language (SDL) are translated into the well-defined and widely implemented ASAM OpenSCENARIO v1.1 and ASAM OpenDRIVE v1.6 standards.
