THE INFLUENCE OF YOUNG AND MALE MOTORISTS ACCIDENT

Abstract

Motorcycles are frequently used as the mode of transportation in Indonesia including the Province of Bali. Motorcycle accidents, however, were reported as 70% of the total road accidents in Bali. with reference to State Police of Bali Province accident data, young (under 26 years) and male motorists at fault significantly contributed to the occurrence of motorcycle accidents. This study investigated the influence of young and male motorist accident factors on motorcycle injuries in Bali using multinomial logit regression. The analyses show that for young motorist accident factors, right angle (side-impact) accidents and male motorists increased the risk ratio between serious and slight injuries by factors of approximately 3 and 4 respectively while head-on accidents were 56.5% less likely to influence fatal injury than slight injury. For male motorist accident factors, road link accidents increased the ratio between fatal injuries and slight injuries by a factor of about 2.7. In addition, accidents due to sideswipe were 53.4% less likely to result in serious injuries than slight injuries. Other significant variables were collision with other vehicles, failure to yield, and the motorcyclist. They were 90%, 62% and 54% respectively less likely to result in fatal injuries than slight injuries. The sensitivity analyses present that a 1% change in accident factors would influence motorcycle injuries between 33% and 34%.
