The Ghanaian transportation sector is facing challenges in maintaining transport infrastructure effectively, leading to inefficiencies and increased costs. A multilevel regression model will be employed to analyse the factors influencing maintenance costs and effectiveness at both regional (level-1) and national (level-2) levels. Data from various depots will be collected through surveys and administrative records, ensuring robust reliability of findings. Analysis revealed significant variations in cost-effectiveness across regions, with some depots achieving up to a 30% reduction in maintenance costs when equipped with advanced technology. Multilevel regression analysis provided a nuanced understanding of the factors affecting depot performance and cost-efficiency, facilitating targeted improvements. Deployment of advanced technologies and standardised operational procedures are recommended for depots to achieve optimal cost-effectiveness ratios.
