Abstract

This study investigates how road infrastructure affects the operational performance of truck drivers at Usangu Logistics Company in Dar es Salaam, Tanzania. Employing a convergent mixed‐methods design, data were gathered from 63 drivers via structured questionnaires and from 33 key informants through semi‐structured interviews, alongside company performance logs. Quantitative analysis yielded a Composite Infrastructure Index mean of 3.94 (SD = 0.88) and revealed a strong positive correlation with delivery delays (r = .62, p < .001). Regression results showed each one‐unit increase in perceived infrastructure strain added 0.83 hours to average delivery time (R² = .38, p < .001). Thematic analysis identified three primary challenges potholes and surface degradation; seasonal flooding and detours; and poor signage and lighting which drivers linked to prolonged transit times and safety risks. These findings align with prior research demonstrating that targeted pavement repairs and drainage improvements can enhance timeliness and reduce accidents. The study recommends routine pothole maintenance, resilient drainage installations, and installation of reflective signage and lighting to improve delivery reliability, lower operating costs, and bolster driver safety.
