The relationship between land use and automobile travel utility: A Multiple Indicators Multiple Causes approach

Gim, Tae-Hyoung Tommy

Highlights • The concept of the utility of auto travel is refined. • The relationship between land use and auto travel utility is examined. • Land use affects auto travel utility, mainly its synergy and affective utility. • Transit availability and land use balance are two major land use variables.

Abstract The relationship between land use and the utility of automobile travel is examined by refining the utility concept, particularly by combining the microeconomic utility theory, which is concerned with the disutility of travel, and the perspective on the positive utility. A conceptual model is accordingly developed and then adjusted considering different purposes of travel. The purpose-specific models are tested through a Multiple Indicators Multiple Causes approach in Seoul, Korea, using datasets from a sample survey and geographic information systems. The major finding is that land use affects the utility mainly by changing synergy and affective utility rather than instrumental utility, which encompasses disutility variables. Among land use variables, the utility is found to be the most sensitive to the number of transit facilities for commuting and shopping travel and land use balance for leisure travel.
