Computation of the International Roughness Index (IRI) given a
longitudinal road profile. The IRI can be calculated for a single road segment
or for a sequence of segments with a fixed length (e. g. 100m).
For the latter, an overlap of the segments can be selected.
The IRI and likewise the algorithms for its determination are defined in
Sayers, Michael W; Gillespie, Thomas D; Queiroz, Cesar A.V. 1986.
