Abstract Evaluating the effectiveness of road humps is very essential in traffic safety and transportation planning. In Uganda, no study has assessed the effectiveness of road humps. This study evaluated the effectiveness of the addition of road humps as a safety intervention in Uganda. Before and after data of the injuries and death that occurred along Kansanga–Gabba and Mukwano road were obtained from Uganda Police Forces (UPF) and used during the analysis. Scikit-Learn library in python 3.7 was used to calculate descriptive statistics and Empirical Bayes (EB) method was used to estimate the effectiveness of the addition of road humps on the road. The results show that the addition of road humps led to a reduction of the road crash death by 38%, 63%, 21%, 31% and 93% for pedestrians, bicyclists, motorcyclists, Light-Duty Vehicles (LDVs), and Heavy-Duty Vehicles (HDVs) respectively. In addition, road crash injuries decreased by 56%, 17%, 13%, 32%, and 74% for pedestrians, bicyclists, motorcyclists, LDVs and HDVs respectively. The inferences from these results will be useful to reduce the continued road crash injuries and death on the road in Uganda.
