ASAM OpenDRIVE defines a file format for the precise analytical description of road networks. Unlike other file formats typically used for navigation systems, ASAM Open-DRIVE's main use is in the area of simulation applications, which require exact road geometry descriptions, including surface properties, markings, signposting and logical properties such as lane types and directions. Road data may be manually created from road network editors, conversion of map data, or originate from converted scans of real-world roads.

The basic principle for describing a road segment in ASAM OpenDRIVE is to first define a reference line (aka anchor line or road center line) and then attach various properties to it. The result is a precise road definition in 3 dimensions. The reference line itself consists of mathematical primitives. It serves as a container for additional properties such as elevation, lateral profiles and lane records. Lanes have various properties like width, markings, materials and other properties. Road segments hold additional properties like road signs, traffic lights, surface profiles, railroad elements, tunnels, bridges and other road objects. Road networks are created by linking road segments either directly to predecessors and successors or via junctions.

The ASAM OpenDRIVE description format contains all static objects of a road network that allow realistic simulation of vehicles driving on roads. In order to render the complete environment, additional description formats for static 3D roadside objects, such as trees and buildings, are needed. Road surface profiles are included from the ASAM OpenCRG file format. The dynamic content of driving simulations, such as vehicle maneuvers, can be described with ASAM OpenSCENARIO. The three standards complement each other and cover the static and dynamic content of in-the-loop vehicle simulation applications.

The data of ASAM OpenDRIVE is organized in a hierarchical structure and serialized in an XML file format. The schema is provided with the standard. The XML file can be easily validated, edited, imported and exported by simulation tools and content editors. The format is technology and vendor independent. Various commercial-off-the-shelf products support ASAM OpenDRIVE as an import and export format.

Next Steps

Road map to further develop ASAM OpenDRIVE

The participants of the Proposal Workshop ASAM OpenDRIVE and ASAM Open CRG (Jan 15 - 16, 2019) decided to start a Transfer Project and a Concept Development Project in parallel. This allows a quicker time to market. The goal of the Transfer Project is to adapt the current version of OpenDRIVE to ASAM requirements. The Concept Project aims at discussing, evaluating and specifying concepts for major extensions of ASAM OpenDRIVE. These concepts will feed into the further development of the standard


Currently the project proposals are written. After publication of the proposals, all members are invited to sign up for participation in the work groups. (To be informed about new proposals subscribe to our newsletter )
