RoadXML The RoadXML© is an open file format for the road networks description used by driving simulators.
Overview
RoadXML© was initiated to contribute to road network format standardization in order to enhance the interoperability between simulators. It is the outcome of the compilation of several original formats (GRS, RNS/RS, RND) developed from 1994 by academic and industrial partners: INRETS, OKTAL , PSA Peugeot Citroën, Renault, THALES.
RoadXML© offers a multi layer description of the environment for fast data access for real time applications. Here are the 4 main layers of information:
- Topological: element’s location and connections with the rest of the network.
- Logical: element’s signification in a road environment.
- Physical: element’s properties (road surface or obstacles).
- Visual: element’s geometry and 3D representation.

- The version 1.3 was released in 2008 and was an alternative file format for the SCANeR II driving simulator, co developed by Oktal and Renault.
- The version 2.0 was released in 2009 as an Open File Format and was renamed RoadXML.
- The version 2.1 was released in June 2010.
