COSIN/io 2D Road Type: spline

In the data block $road_type, COSIN/road reads:

Name of input variable	Unit	Meaning
`periodic`	0/1	0 (Default) Spline data is evaluated in a non-periodic manner. 1 Spline data is evaluated periodically, as a repeating sequence.

After reading the data block $road_type, COSIN/road searches for the spline data in the sub-data block $spline_data. This data block contains two data columns: the first is travel distance in m, the second is road height in mm. For the syntax of spline data definitions, please refer to the COSIN/io documentation.
