Introduction Machine learning, a branch of artificial intelligence, investigates the mechanisms by which knowledge is acquired through experience. A large number of machine learning methods and algorithms have been developed, including neural computing (Freeman and Skapura, 1991), case- based reasoning (Kolodner, 1993), genetic algorithms (Goldberg, 1989), and inductive learning (Quinlan, 1988). These approaches form the essential toolbox of methods to extract useful information from data sets built into the knowledge base of expert systems. It has been argued that these computational methods are not only useful for the design and implementation of effective and efficient decision support and expert systems, but also as support tools in furthering scientific knowledge discovery above and beyond what conventional methods of inquiry have so far permitted. In the domain of the Spatial Sciences, this viewpoint is forcefully advocated in the research white paper on "Spatial Analysis in a GIS Environment" of the University Consortium for Geographic Information Science (UCGIS, 1997). In this chapter, we discuss the merit of inductive learning as an analysis tool in spatial decision making theory. We analyze the capability and applicability of Ross Quinlan's (1993) C4.5 decision tree induction algorithm to the class of problems involving the choice among travel destination within an urban area. The chapter reviews the relevant destination choice modeling literature, des
