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.

History

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 2011

Since the version 2.1, an Open Source parser for RoadXML is also available on sourceforge.
