I COST deltar forskare och experter från forskningsorganisationer,universitet, högskolor, institut och industri från hela Europa.
COST har ingen central finansiering för forskningen. Däremot bidrar COST med ersättning för resor till Management Committee, (MC)- möten, workshops och tryckkostnader för resultatspridning.
En COST-aktion är en överenskommelse mellan de deltagande länderna att samordna FoU inom ett visst område, vilket beskrivs iMemorandum of Understanding, ( MoU).

1. Performance Indicator details Sheet 1
Indicator Name: Longitudinal Evenness, PI_E
Description of Index: Longitudinal Evenness is the deviation of the longitudinal profile from a straight reference line in a wavelength range of 0.5 m-50 m. The reference line is usually the intersection of the profile plane and the horizontal plane.
Possible TPs: International Roughness Index, Evenness, Wavelength, Spectral Density, Longitudinal Profile Variance and others.
2. Proposed Technical Parameter(s)
Technical Parameter(s): International Roughness Index, IRI Units: mm/m
3. Proposed Transformation Function(s), usage and Limitations
Proposed Transformation Function(s):
)0316.07142.01733.0,5(_ 2 −×+×= IRIIRIMinEPI [1]
)816.0,5(_ IRIMinEPI ×= [2]
Usage of Transformation Functions(s):
Transformation [1] was developed to create a more restrictive range than transformation [2] (see range and sensitivity below). The choice of transformation function should be based on which range best suits the user’s network.
Limitations of Proposed Transformation Function(s):
Transformations [1] and [2] are both suitable for all pavement types (flexible, semi-rigid and rigid). Transformations [1] and [2] are both suitable for motorways and primary roads.
4. Range and Sensitivity of Transformation Functions
