The definition of a new standard to describe dynamically changing objects in a driving simulator scenario and the introduction of a Open Source tool to generate roadsystems were the main aspects of the presentation on booth number one at the Driving Simulation Conference in Tübingen. HLRS shared the booth with asc(s, the Automotive Simulation Center Stuttgart (http://www.asc-s.de), who coordinates the project OpenSCENARIO.
The goal of OpenSCENARIO is to establish a software-independent format to facilitate the exchange of simulation contents among different simulators. A mindmap is already available, containing parameters to describe vehicles, environment conditions, maneuvers and routes as well as the attitude and behaviour of the driver. The attributes have been gathered according to the requirements of the car manufacturers and OpenDRIVE® users. OpenDRIVE® is an already established format, providing a common base to describe track-based road networks. OpenDRIVE® is a registered trademark of VIRES Simulationstechnologie GmbH. Beside asc(s, VIRES and HLRS, Porsche, Daimler and Opel are participating in OpenSCENARIO.
To ease the creation of virtual driving simulator tracks HLRS has developed an OpenSOURCE® editor, the ODDLOT. In ODDLOT the user can load OpenStreetMap data, change the curvature of the tracks, adjust the width of the lanes, and the roads height level. The linkage between roads and lanes, and junctions can be automatically generated or created step by step. A signal and an object editor allow the placement of traffic lights and signs, as well as barriers, tree, poles and other objects, standing close to the road. The user can choose from a catalog of predefined elements or create his own in an XML file.
ODDLOT is part of COVISE, the Collaborative Visualization and Simulation Environment of HLRS, an Open Source package (LGPL2+) available on GitHub. ODDLOT is adapting to the ongoing extensions of the OpenDRIVE® standard, making it possible to describe dynamically changing elements in the future.
