Pavement performance models are the main element in any Pavement Maintenance Management System (PMMS). The objectives of this paper are to investigate the factors that affect the pavement condition of the Riyadh street network, to develop pavement performance models, and to validate the developed models. The urban distress index (UDI) was used as a measure of pavement condition. The factors included in the models were pavement age, traffic level, availability of drainage system, and maintenance type. A separate model was developed for pavement sections with utility cut patching. All the developed models were found statistically significant in predicting pavement condition at the 95 percent confidence level.
