A statistical assessment of road traffic casualties in Nigeria


Author(s): Musa GK, Omaku PE and Aliyu Aminu Ohindase

Abstract: Road traffic crashes are the second leading cause of death and injuries among different age groups. The Federal Road Safety Commission reported that Nigeria has the Africa’s highest rate of fatality from automobile accident. Thus, this study aimed at carrying out a statistical assessment of road traffic casualties in Nigeria. The data used in this study is a secondary data collected from Federal Road Safety Corps Statistical Digest for the period 2004-2020. Exponentially Weighted Moving Average (EWMA) and two factor analysis of variance were used in analyzing the data. The EWMA control chart scheme was compared by varying the weighted parameter (0.25, 0.50 and 0.75). It was observed that EWMA control chart is sensitive in detecting a small shift in the process however, it was noticed that higher weights assigned to current data on road traffic casualties support smoothing than low weights, and so the higher the weights the better values of EWMA obtained for the datasets. Also, it was discovered that the mean reported cases of road casualties were higher in North-Central, South-West and North-West geo-political zones. Based on these findings, it was recommended that higher weighted parameters should often be used since it provides a more-smooth trend of EWMA values which may be employed for forecasting purpose. Also, the Federal Road Safety Commission and other road traffic agencies who are in charge of road safety activities should increase their earnest effort by deploying more Road Safety officers to strategic locations on the high ways, particularly in the North Central Zone of Nigeria as this will aid in reducing the cases of road casualties in the area.
