Abstract
This Data Descriptor focuses on the application of a Bayesian hierarchical model for evaluating municipal infrastructure assets systems in Uganda. A Bayesian hierarchical model was developed to analyse data from municipal infrastructure projects in Uganda. This approach accounts for variability across different regions and project types. The analysis revealed significant variation in the cost-effectiveness of assets managed by local governments, with some systems showing a 20% improvement over others after adjustments were made. The Bayesian hierarchical model successfully identified key factors influencing asset performance and provided recommendations for improving resource allocation efficiency. Based on the findings, municipalities should prioritise maintenance of critical infrastructure assets to enhance overall system effectiveness.
