Abstract

This study assesses risk in road transportation in Ekiti State, Nigeria through a number of factors as well as the various ways by which these factors are perceived through Pearson correlation analysis. Six roads were identified as case studies from which information about how the users perceived risk was obtained mainly by administering questionnaires. The responses to the 23 questions which were developed based on the risk factors were analyzed statistically to obtain their relationships in terms of their correlation coefficients and R-squared values. The most dominant risk factors with respect to the roads considered as case studies were identified and the relationships between them were determined. The results showed that the most correlated risk factors are "drinking and driving (DAD)", "using a mobile phone (hands free) and driving (UMP(hf)AD)", "taking medicine and driving (TMAD)" and "using a mobile phone (hands free) and driving (UMP(hf)AD)" with Pearson correlation coefficient of 0.9772 and R-squared value of 0.9549.Este estudo avalia o risco no transporte rodoviário no Estado de Ekiti, Nigéria, por meio de uma série de fatores e das diversas maneiras pelas quais esses fatores são percebidos, utilizando uma análise de correlação de Pearson. Utilizou-se como estudo de caso um conjunto de seis estradas daquele estado, sendo extraídas informações sobre como os usuários percebem o risco de acidentes por meio de aplicação de questionários. As respostas às 23 perguntas desenvolvidas com base nos fatores de risco foram analisadas estatisticamente com vistas à obtenção de relações em termos de seus coeficientes de correlação e valores de R-quadrado. Identificou-se, assim, os fatores de risco mais dominantes e suas interrelações. Os resultados mostraram que os fatores de risco mais correlacionadas entre si são "beber e dirigir" e "usar telefone celular (mãos livres) e dirigir", bem como "tomar os medicamentos e dirigir" e "usar telefone celular (mãos livres) e dirigir", com coeficiente de correlação de Pearson de 0,9772 eo valor de R-quadrado de 0,9549.
