Purpose and goal
To support the development of autonomous vehicles the main purpose of this work revolved around standardization of traffic scenario descriptions. The project evaluated and contributed in the development of OpenSCENARIO, an initiative to establish a standardized description format for driving scenarios. In particular, the project addressed the question of suitability of OpenSCENARIO for use cases and test facilities of relevance to the industry and research. The format’s potential was demonstrated across several test environments and traffic scenarios.
Expected results and effects
Relevant key scenarios involving maneuvers on country road, intersection and highway with onramp were defined and described in the OpenSCENARIO format. Eight strategic test environments of various kinds, ranging from physical test track and advanced driving simulators to low cost desktop solutions, were adapted to support OpenSCENARIO and common road description formats. The software developed in the project, to parse and execute driving scenarios, has been released as Open Source under MPL 2.0 license to stimulate dissemination and further development of OpenSCENARIO.
Planned approach and implementation
The project set out to define relevant driving scenarios before getting familiar with the OpenSCENARIO format, so as to avoid any bias arising from understanding the format and its limitations. The prototype scenarios were then translated into the OpenSCENARIO format, and software was developed to parse and execute the driving scenarios in runtime. Finally, this software was integrated and tested in a wide range of test environments, for the purpose of demonstration of the designed scenarios and, consequently, the format’s potential.
