their elevation profiles are all attached to the reference line. The ASAM OpenDRIVE road network is modelled along the reference line, which is the core piece of every road. This facilitates a high degree of specialization for individual applications (usually simulations) while maintaining the interoperability that is required for the exchange of data between different applications. The format is organized in nodes that can be extended with user defined data. Road data may be manually created from road network editors, conversion of map data, or originate from converted scans of real-world roads. Providing a standardized format for road descriptions also enables the industry to reduce the cost of creating and converting these files for their development and testing purposes.
With the help of ASAM OpenDRIVE, these road network descriptions can be exchanged between different simulators. The main purpose of ASAM OpenDRIVE is to provide a road network description that can be fed into simulations to develop and validate ADAS and AD features. The road networks that are described in the ASAM OpenDRIVE file can either be synthetic or based on real data. Furthermore, now this mode includes crosswalks for pedestrian navigation, and some safety measures to prevent vehicles from falling off the map. The data that is stored in an ASAM OpenDRIVE file describes the geometry of roads, lanes and objects, such as roadmarks on the road, as well as features along the roads, like signals. The procedural generation of maps from OpenDRIVE files has been refined to smooth the merge of different roads at junctions. The ASAM OpenDRIVE format provides a common base for describing road networks with extensible markup language (XML) syntax, using the file extension xodr.
