13.5 Object material
Objects placed on a road, such as patches, may consist of a different material than the surrounding road. Therefore, the material of the object may be defined separately. In ASAM OpenDRIVE, it is possible to describe the surface, roughness, and friction. The values depend on the application and are not defined in ASAM OpenDRIVE.
Elements in UML model
<material> element
In ASAM OpenDRIVE, the outlines of objects are represented by the <material> element within the <object> element.
UML class: t_road_objects_object_material XML tag: <material> (Multiplicity: 0..*)
Describes the material properties of objects, for example, patches that are part of the road surface but deviate from the standard road material.
Supersedes the material specified in the <road material> element and is valid only within the outline of the parent road object.
