Usage Considerations

Users of this data set should keep in mind the International Roughness Index is not a simple measure. Only a trained engineer/technical personnel could interpret the meaning of the measure properly.

On the rut depth measurement, it is not appropriate to look at the maximum value for gaging the pavement quality. Maximum values can distort the picture. In fact, maximum ruts can sometimes be erroneous based on the laser reading into a crack and need to be considered in context with the overall pavement condition. The averaged values are better representations for rutting. Even on the averaged values, engineering decision are not made on single 50-metre readings, but on statistics over the length of entire projects. This also applies to the IRI.
