Abstract
Functional criteria have been mostly defined in urban pavements using subjective methods, rather than by means of objective and repeatable procedures. The Whole
Body Vibration, the Heart Rate Variability, and new technologies to determine the
IRI (International Roughness Index), are nowadays available. For that, an analysis of
available technologies is made under a PC-O (Pavements Clients-Oriented) integral
perspective, including simulations with the HDM-4 computer program. The IRI
criteria for speeds allowed on urban roadways, i.e. the so-called IRIcity criteria, are
proposed in the paper.
