        To specify and evaluate road excitation, COSIN/road uses one central subroutine evrmr (COSIN environmental models: road main routine).
        Road Profiles and Obstacles in COSIN/io Format
        If COSIN/road detects the road file in COSIN/io format, it first tries to read certain information common to all road types within this format (see Data Common to all COSIN/io Style Road Types).
        Road Profiles and Obstacles in TeimOrbit Format
        If COSIN/road recognizes the road data file is in TeimOrbit format (typically, the file name extension is rdf), it branches into the respective reading and evaluation routines.
        TeimOrbit 2D Road Type: drum
        TeimOrbit 2D Road Type: flatbelt
        TeimOrbit 2D Road Type: hydraulic_test_rig

Superposition of TeimOrbit 2D Roads with 3D Roads

All TeimOrbit 2D roads can be superimposed by a triangularized or RGR-type 3D road. This is achieved by specifying the name of the respective 3D road data file in the data section [MODEL] of the 2D road data file. This technique, for example, can be used to define a non-flat hydraulic test-rig cylinder surface by means of RGR data:


Name of input variable	Unit	Meaning
`superimpose_data_file`	-	Name of the 3D road data file (triangular or RGR type) to be superimposed to the 2D data.
