Transport maintenance depots (TMDs) are critical for ensuring efficient vehicle operations in Kenya's transport sector. However, there is limited empirical evidence on their operational efficiency. A DiD approach was employed to analyse pre- and post-intervention data from a sample of TMDs. The model accounts for potential confounders through fixed effects, providing robust estimates of efficiency gains. The analysis revealed that the implementation of standardised maintenance protocols led to an average increase in vehicle operational efficiency by 15% over a two-year period. This study provides empirical evidence on the impact of TMD system improvements and offers actionable insights for enhancing transport sector operations in Kenya. Further research should focus on long-term sustainability and scalability of these interventions across different regions. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
