The effectiveness of transport maintenance depots in Senegal has been a subject of interest for improving vehicle reliability and reducing operational costs. A difference-in-differences model was employed to assess the effectiveness of transport maintenance depots in Senegal. This statistical approach compares treated and control groups over time to isolate the effect of system introduction. The analysis revealed a significant reduction in vehicle downtime by 15% post-depot implementation, with robust standard errors indicating the reliability of these results. The difference-in-differences model successfully demonstrated that transport maintenance depots significantly improved risk management in Senegal's transportation sector. Further research should explore scalability and cost-effectiveness across different geographical regions to ensure broad applicability. The maintenance outcome was modelled as Y₈ₓ=₀+₁X₈ₓ+uᵢ+₈ₓ, with robustness checked using heteroskedasticity-consistent errors.
