INTERACTIVE GEOVISUALIZATION OF ACTIVITY-TRAVEL PATTERNS USING THREE-DIMENSIONAL GEOGRAPHICAL INFORMATION SYSTEMS: A METHODOLOGICAL EXPLORATION WITH A LARGE DATA SET

In the past, a major difficulty in the analysis of disaggregate activity-travel behavior has arisen from the many interacting dimensions involved. Researchers are often forced to decompose activity-travel patterns (ATPs) into their component dimensions and focus on only 1 or 2 at a time, or to treat them as a multidimensional whole using multivariatte methods to derive generalized ATPs. This paper describes several GIS-based, 3-dimensional (3D) geovisualization methods for dealing with the spatial and temporal dimensions of human ATPs at the same time, while avoiding the interpretative complexity of multivariate pattern generalization or recognition methods. These methods are operationalized using interactive 3D, GIS techniques and a travel diary data set collected in the Portland (Oregon) metropolitan area. Several advantages in using these methods are demonstrated and discussed.
