RoadXML

<h2 id="overview">Overview</h2>
<p>RoadXML was initiated to contribute to road network format standardization in order to enhance the interoperability between simulators.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> It is the outcome of the compilation of several original formats (GRS, RNS/RS, RND) developed in 1994 by academic and industrial partners: <a href="/facts/Institut_national_de_recherche_sur_les_transports_et_leur_s%25C3%25A9curit%25C3%25A9/j9CRjwsm">INRETS</a>, Oktal, <a href="/facts/PSA_Peugeot_Citro%25C3%25ABn/WFw49Uyq">PSA Peugeot Citroën</a>, <a href="/facts/Renault/obzoLxSN">Renault</a>, <a href="/facts/Thales_Group/vuBBokok">Thales</a>.
</p><p>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:
</p>
<ul><li>Topological: element’s location and connections with the rest of the network.</li>
<li>Logical: element’s signification in a road environment.</li>
<li>Physical: element’s properties (road surface or obstacles).</li>
<li>Visual: element’s geometry and 3D representation.</li></ul>
<h2 id="history">History</h2>
<p>Until its 2.0 version, RoadXML was called RND (for Road Network Description):
</p>
<ul><li>The version 1.0 was released in 2007 and used by PSA Peugeot Citroen.</li>
<li>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.</li>
<li>The version 2.0 was released in 2009 as an <a href="/facts/Open_format/TKcCW6mA">open file format</a> and was renamed RoadXML.</li>
<li>The version 2.1 was released in June 2010.</li>
<li>The version 2.2 was released in September 2010<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a></li>
<li>The version 2.3 was released in December 2011<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a></li>
<li>The version 2.4 was released in July 2013<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a></li>
<li>The version 2.4.1 was released in July 2016<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a></li>
<li>The version 2.4.6 was released in April 2019<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a></li>
<li>The version 3.0.0 was released in March 2020<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a></li></ul>
<p>
Since the version 2.1, an <a href="/facts/Open_source/7X9rCdz4">open source</a> parser for RoadXML is also available on <a href="/facts/SourceForge/lxYAgUAX">SourceForge</a>.
