A decision support concept to the historic pedestrian bridges rehabilitation planning

Historic pedestrian bridges are the crucial assets for the villages, cities or regions transportation, not just because of the connections they provide but also for their cultural aspects, as objects build in important parts of the history. For their proper functioning and acceptable serviceability and security it is very important to develop a quality historic bridge management. For a quality management, an expert assessment of bridges, precisely its elements is needed, because this way current condition of bridge is determined and by that a proper activity can be defined. Activity can include maintaining, repairs, replace, remove or rehabilitation. In this research only rehabilitation is observed as is decided by experts who made visual inspection of those bridges, so the crucial part of managing historic pedestrian bridges is the planning of their rehabilitation which so far has been done unsystematically and unorganized, often lead with political interests. For this reason a new decision support concept (DSC) to the historic pedestrian bridges rehabilitation planning is designed in combination with multicriteria analysis. Goal hierarchy structure is formed in three levels by three different stakeholders' groups, containing main goal, sub-objectives and criteria. The Analytic Hierarchy Process (AHP) method is used for definition of the criteria relative importance (weights), then the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used for priority ranking of historic bridges for the rehabilitation. The main goal of this research is to develop a model of decision support concept that will assist to the final decision maker to carry out the rehabilitation planning of historic bridges in systematic and organized manner. The model was validated on the case of historical pedestrian bridges in the area of Split-Dalmatia County (SDC), built during or before the Austro- Hungarian Monarchy.
