Abstract


Bus dwell time at terminals is a critical factor affecting public transportation efficiency, service reliability, and passenger satisfaction. This study examines the relationship between bus dwell time and selected terminal-based factors. The data collected at Terminal 3 of Oshodi Transport Interchange in Lagos State, Nigeria were used to derive headway - difference between consecutive bus arrival times; dwell time - difference between bus arrival and departure times; boarding time - difference between boarding start and end times, and the total number of passengers on board a bus at departure. Pearson correlation analysis indicated a significant relationship between dwell time, boarding time and headway (p < 0.001).  Whereas headway has a negative relationship with dwell time(r = -0.193), boarding time and number of passengers are positive (r = 0.226 and r = 0.343 respectively). Regression analysis indicates that boarding time and number of passengers jointly explains 16.4 % of dwell time variability, whereas headway does not have a significant influence in the model. The diagnostic tests indicate that the predictors show no problematic multicolinearity (VIF = 1.000, i.e. < 5.0). While, the linearity of the association between the predictors and dwell time was validated by ANOVA linearity test (F = 48.05, p < 0.001). Therefore, transit managers and planners seeking to improve operational efficiency and passenger satisfaction could consider shortening boarding time and improving passenger management.
