Mixed-methods evaluation finds process-control systems improve transport reliability in Tanzania, highlighting the need for continuous enhancement.
This study examines the effectiveness of process-control systems in Tanzania's transport sector through a methodological evaluation. A mixed-method approach combining econometric techniques will be employed, including the application of robust standard errors for uncertainty assessment. Initial findings suggest that process-control systems have improved system reliability by 15% in key transport sectors such as road and rail. The study concludes that implementing and monitoring process-control systems can significantly enhance transportation efficiency and safety, contributing to better infrastructure development. Transport authorities should prioritise the implementation of continuous improvement initiatives based on feedback from pilot projects. The maintenance outcome was modelled as Yᵢₜ=β₀+β₁Xᵢₜ+uᵢ+εᵢₜ, with robustness checked using heteroskedasticity-consistent errors.
