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 in 1994 by academic and industrial partners:

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
