Implementation of a rule-based deterioration model for dual carriageway road networks
This paper describes a rule-based deterioration model used in a pavement management system (PMS). The model was developed specifically for dual carriageway road networks and is currently used for performance modelling and planning on two major toll road concession contracts in South Africa. The model provides a robust deterioration model approach that is easy to calibrate and implicitly models the philosophy of the road management authority. The paper focuses on a key aspect of the model, namely the fuzzy logic-based rule system that is used for deterioration modelling and assignment of interventions. The technical aspects of the model are discussed, with specific focus on the potential advantages of the rule-based model over more conventional equation-based approaches. Also outlined is the method for explicit definition and handling of work areas spanning over two carriageways. An overview of the modelling process is provided and typical model outputs are shown. The paper concludes by highlighting lessons learnt during the initial implementation of the model and makes recommendations for implementation in a more general context.
