Risk perception factors and their influence on road transportation

Fatores de percepção de risco e sua influência sobre o transporte rodoviário

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.
