The Analysis of Household Car and Motorcycle Ownerships Using Poisson Regression (Case Study: Denpasar-Bali)
Abstract: This study examines
household factors which influence car and motorcycle ownerships in the city of
Denpasar, Bali using a Poisson regression model. The study found that the
increase in number of workers and students in a household may affect the
probability of owning motorcycle by the household. Meanwhile, the increase in
number of family member and total travel distance may affect household
preference to own a car. In addition, car capacity and other factors may
increase household preference to own a car. None of these variables, however, significantly
influenced on both car and motorcycle ownerships. In other words, the household
had a separate preference when purchasing either a car or a motorcycle. The
sensitivity analyses show a-50% increase in number of workers and students may
increase motorcycle ownership by 1 unit and a-50% increase in total travel distance
by all household members may increase car ownership by 1 unit.
