Road traffic mortality in Morocco: Analysis of statistical data

摘要

Over the last decade, around 3500 people lost their lives in road accidents each year in Morocco. Between 2008 and 2017, the number of accidents has seen an increase of 38.11%. Several factors may contribute to the so-called “war on the roads”, such as the behavior of drivers or vehicle condition. Since human behavior is not always the leading cause of traffic crashes, in this work, we propose to study the effect of the environment and road conditions on accident mortality. The study is based on statistical data of accidents that caused death or bodily injuries in Morocco in 2017. The Case Fatality Rate (CFR) indicator was used to measure the severity of accidents, and the technique involved is the well-known non-parametric Analysis of Variance (ANOVA). Thirteen factors were taken into account to describe the state of the infrastructure and the physical conditions of roads. The analysis results show that the factors studied have a significant effect on accident fatality. More specifically, the type of intersection and the location proved to be the variables that contribute more to accident fatality.
