Car dependence is a fundamental problem in the sustainability of cities with lowdensity
suburban sprawl. Increasing the use of public transport is one of the policy objectives
commonly adopted to overcome this problem. It is essential to study journey to work travel
behavior by car and bus. This paper applied preference function to analyze travel behavior and
Moran?s I spatial statistic to evaluate the spatial association. The results indicated that the
commuting preferences of residents have moved towards distance maximization. In general, bus
was preferred for shorter distance trips whilst car was preferred for longer distance trips. Unlike
car, by increasing distances from the Central Business District, residents tended to use bus for
shorter distance trip. A significant positive spatial association was identified for both the slope
preferences by car and bus where zones with a preference towards longer or shorter trips tended
to travel to zones with similar preferences.
