The ASAM OpenDRIVE format provides a common base for describing road networks with extensible markup language (XML) syntax, using the file extension xodr. 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 road networks that are described in the ASAM OpenDRIVE file can either be synthetic or based on real data.
The main purpose of ASAM OpenDRIVE is to provide a road network description that can be fed into simulations to develop and validate
The format is organized in nodes that can be extended with user defined data. 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 ASAM OpenDRIVE road network is modelled along the reference line, which is the core piece of every road. Roads, lanes, incl. their elevation profiles are all attached to the reference line.
Objects representing features, such as signals, can be placed by using either the reference line or the global coordinate system, the road network is placed in. This can be seen in the above image. The reference line (blue line in the middle) is in the center of the road, the lanes (blue and light green) are attached to this reference line. The signs next to the road are placed in the s/t-coordinate system.
In ASAM OpenDRIVE several roads form a road network and can be connected. ASAM OpenDRIVE can be seen as a construction kit of different road sections. The overall road network is composed of individual sections interconnected with each other.
The image on the right shows how individual road segments interconnect e.g. with a junction. The shownXML snippet gives a short overview on how the linking of road segments can be used in ASAM OpenDRIVE. These links can support the driving logic of simulated traffic, especially for routing purposes, leaving more resources for the actual work of validating and developing AD driving features. In junctions, each possible connection between entry roads is connected via “connecting-roads”. Due to this mechanism connecting roads are the only roads within ASAM OpenDRIVE with overlapping surfaces.
In ASAM OpenDRIVE not only roads are linked but also the lanes between roads. These lane links can again support simulated traffic. They are also important for the visualization of the road network when the reference line of connecting roads and roads that enter the junction are not necessarily aligned (this is the case e.g. in junctions).

ASAM OpenDRIVE V1.6.0 is now available in Chinese. Please download the Chinese version in the blue download box on the right. The Chinese version will soon be available on the C-ASAM website.
ASAM was entrusted with the further development of OpenDRIVE in 2018 (READ MORE). The first version released by ASAM is ASAM OpenDRIVE V1.6. For a matter of completeness, we are providing the predecessor versions OpenDRIVE V1.5 and OpenDRIVE V1.4 on our website:
OpenDRIVE V1.5 and OpenDRIVE V1.4. were published by VIRES Simulationstechnologie GmbH. These versions are the intellectual property of VIRES Simulationstechnologie GmbH.
