RESUMO

The development of conservation programs, starting from the previous knowledge of pavements condition, makes possible to maintain certain quality levels in the roadway system. However, in a lack of budget scenario, to achieve those quality levels the decisions have to be taken considering a pavement maintenance and rehabilitation (M&R) prioritization program. The general objective of this work is to propose urban roadways prioritization model based on multicriteria decision analysis aggregated to geographical information system (GIS), considering objective and subjective criteria in the decision support. A case study was performed at the city of São Carlos, state of São Paulo, Brazil, using a preliminary study of pavement condition and physical and geometric characteristics. It was also performed a research about the current situation regarding the procedures for pavement maintenance and rehabilitation management in brazilian medium-sized cities. The model developed in this work, that uses AHP (Analytic Hierarchy Process) and GIS is adapted to the reality of the brazilian medium-sized cities, but it maintains the application viability in cities of other dimensions, since the particularities of those cities are considered. It is dedicated to help administrators of government agency responsible for the evaluation of urban roads and pavement conservation planning.
