RoadXML is an open file format for the road networks description used by driving simulators.

Overview[edit]

RoadXML was initiated to contribute to road network format standardization in order to enhance the interoperability between simulators.[1] It is the outcome of the compilation of several original formats (GRS, RNS/RS, RND) developed in 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 four 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.

History[edit]

Until its 2.0 version, RoadXML was called RND (for Road Network Description):

  • The version 1.0 was released in 2007 and used by PSA Peugeot Citroen.
  • 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.
  • The version 2.2 was released in September 2010[2]
  • The version 2.3 was released in December 2011[3]

Since the version 2.1, an open source parser for RoadXML is also available on SourceForge.
