Abstract

Aim:

This paper provides model to find the effect of traffic flow, proportion of motorcycle, speed, lane width, and the availabilities of median and shoulder on motorcycle accidents at urban roads in Indonesia.

Methods:

A generalized linear model with quasi likelihood approach was used to develop the model.

Results:

Traffic flow, proportion of motorcycle, speed, lane width, the availabilities of median and shoulder were found significant in explaining motorcycle accidents.

Conclusion:

These findings can be used as information for engineers to develop action programs to improve road safety for urban roads in Indonesia.

Keywords: Motorcycle accidents, Generalized linear models, Quasi likelihood, Prediction model, Road accidents, Urban road.
