Transport maintenance depots play a crucial role in ensuring the reliability and efficiency of urban transport systems in Kenya. However, their performance can vary significantly due to operational challenges such as inadequate resources, improper scheduling, and unpredictable demand. A randomized field trial was conducted in Nairobi's urban areas. Depots were randomly selected for monitoring over six months. Data collection included operational logs, staff surveys, and user feedback forms. A mixed-methods approach combining quantitative metrics (e. g. , reliability index) with qualitative insights was employed to ensure comprehensive evaluation. The analysis revealed that depot capacity utilization varied significantly between depots, ranging from 60% to 85%. Staff turnover rates were also noted as a critical issue affecting service quality and system reliability. User satisfaction levels indicated areas for improvement in depot efficiency and resource allocation. This study provides empirical evidence on the operational challenges faced by transport maintenance depots in Kenya, highlighting the importance of capacity utilization and staff management for enhancing overall system reliability. Based on findings, recommendations include optimising depot capacities to match demand patterns, implementing targeted training programmes for staff, and improving resource allocation strategies to enhance service quality and efficiency.
