Predicting the Influence of Accident Related Factors on Motorcycle Fatal Accidents Using Logistic Regression (Case Study: Tabanan, Bali)
Abstract: There were about
86.62% motorcycle accidents of all road accidents during period 2003-2008 in Tabanan regency, Bali Province.
Of those motorcycle accidents, 50% included motorcycle fatal accidents. This study investigates the
influence of accident related factors on
motorcycle fatal road accidents during period 2003-2008 in the Regency of
Tabanan, Bali, using logistic regression technique. Based on accident data,
eight predic-tor variables were employed in the developed models. The study
found that the odds of motorcycle fatal accident due to motorists failed to
yield and collision with light vehicles were both about 0.4 times lower than
for acci-dent due to other causes and collision with motorcycles respectively.
Thus, the probabilities of failed to yield and light vehicle were about 30% and
28% respectively contributing on motorcycle fatal accidents.
