Time series modeling of road traffic accidents in Amhara Region

Abstract

Road traffic accidents (RTA) are commonly encountered incidents that can cause injuries, death, and property damage to members of society. Ethiopia is one of the highest incident rates of road traffic accidents. Report of Transport and Communication from 2012 to 2014, shows an increment in the number of traffic accidents in Ethiopia. Amhara region accounted for 27.3% of the total road traffic accident-related deaths in Ethiopia during the year 2008/9, which is the highest share among all regions in Ethiopia. The current research aims to model the trend of injury, fatal and total road traffic accidents in the Amhara region from September 2013 to May 2017. Monthly reported traffic accidents were obtained from the traffic department of the Amhara region police commission. The most universal class of models for forecasting time series data called Auto-regressive Integrated Moving Averages (ARIMA) models were applied to model the trends and patterns of road traffic accident cases in the Amhara region. The average number of observed injury RTA, fatal RTA, and total RTA were 27.2, 14, and 78.2 per month respectively. It was observed that a relatively large number of RTA’s are reported on Tuesday, Thursday, and Saturday relative to other days of the week. The data also reveals that more than 60% of accidents involve drivers between the ages of 18–30 years. ARIMA (2,0,0) (1,0,0) ARIMA (2,0,0) and ARIMA (2,0,0) (1,1,0) were fitted as the best model for total injury accidents, fatal RTA and total RTA data respectively. A 48 months forecast was made based on the fitted models and it can be concluded that road traffic accident cases would continue at the non-decreasing rate in the Amhara region for the predicted periods. Therefore, the findings of this study draw attention to the importance of implementing improved better policies and close monitoring of road trafficking to change the existing non-decreasing trend of road traffic accidents in the region.

The epidemiology of road traffic accidents and associated factors among drivers in Dilla Town, Southern Ethiopia

“…In Ghana, 74.0% were reported to have been involved in crashes in the past year before the study ( 20 ). A systematic review, GIS, and meta-analysis study in Iran showed that the prevalence of road traffic accidents was 51.50% ( 19 ), and a study was conducted in Adama (54.7%) ( 29 ). Moreover, it is not consistent with a hospital-based study conducted in Wolaita Zone, SNNPR, Ethiopia, in which 62.5% of trauma victims were due to road traffic accidents ( 30 ).…”

“…According to a global status assessment on road safety, Ethiopia has at least 114 deaths per 10,000 vehicles per year, compared to only 10 in the United Kingdom and Ireland and 60 in 39 Sub-Saharan African nations ( 23 ). A number of studies have also indicated that Ethiopia has one of the world's highest fatality rates per vehicle ( 23 , 24 , 29 – 32 ). According to the World Health Organization (WHO) estimate, in 2013, the prevalence of road traffic fatalities in Ethiopia was 25.3 per 100,000 population, and the rate is among the highest in the world ( 25 ).…”

Research on Active Safety Situation of Road Passenger Transportation Enterprises: Evaluation, Prediction, and Analysis

“…Yousefzadeh-Chabok et al [ 20 ] used the SARIMA (1, 1, 3) (0, 1, 0)12 model to predict the road traffic accident fatality rate in Zanjan Province, Iran, from 2007 to 2013. Getahun [ 21 ] used the ARIMA model to predict the number of accidents per month in the Amhara region, Ethiopia. Rabbani et al [ 22 ] used the Seasonal Autoregressive Integrated Moving Average (SARIMA) and Exponential Smoothing (ES) models to predict monthly accident rates in Pakistan.…”

Building a Statistical Model to Forecast Traffic Accidents for Death and Injuries by Using Bivariate Time Series Analysis

“…The World Health Organization (WHO) has found that car accidents cause the most deaths among people aged 5 to 29 worldwide, and in 2020, 10726 people died in car accidents in Iraq, which is 7.32 percent of all deaths. The average death rate is 34.41 per 100000 population, and Iraq is 37th in the world (WHO, 2020;Getahun, 2021). Accidents on the road can happen anywhere in the world, but the specific things that cause them to happen vary a lot from place to place.…”
