A methodology is proposed for the identification of uniformly behaving deterioration regions of infrastructure facilities. Such `homogeneous' regions constitute the basic units that should be used for condition assessment and maintenance decision making. The main elements of the proposed methodology are: (i) identification of the nature of the spatial interdependence amongst the distresses; (ii) representation of distress occurrences by a continuous function that avoids any a priori discretization scheme; and consequently, (iii) definition of uniformly behaving units that accurately characterize the true levels of deterioration. The proposed methodology is also essential for reducing large amounts of data, collected by automated systems, without loss of information thus bridging the gap between detailed condition data and the information necessary for the management of infrastructure facilities. The proposed methodology is applied to data collected on a 15 kilometer long highway facility; the results demonstrate its theoretical validity and functional feasibility.
