Abstract
Traffic generated from residential land uses and traffic attracted to employment zones contributes the most to person kilometers of travel. The journey-to-work travel depends on the spatial distribution of residential and employment zones. The fundamental importance of the average length of commuting trips as a measure of sustainability is widely recognized by researchers. Relationship between the urban structure and trip length is investigated considering the journey-to-work travel behavior. The preference function, which considers both the proportion of travelers from a designated zone and the proportion of total metropolitan jobs, is helpful in the estimation of the trip length with changing of the relative home and workplace. The methodology is applied to Sapporo using person trip data for 1994.Keywords: Journey-to-work Travel, Urban Structure, Preference Function
