Analysis of Commute Atlanta Instrumented Vehicle GPS Data: Destination Choice Behavior and Activity Spaces

The Commute Atlanta Instrumented Vehicle GPS Data is currently the longest running data source available for the comprehensive analysis of individual trip and activity demand. Among other exciting research opportunities for mobility analysis, the longitudinal data have opened the field for testing hypotheses developed to descr ibe human spatial behavior over time. This paper provides an overview of how the unique GPS data can be used in travel behavior analysis. At the same time, the paper provides anal ytical results of destination choice and activity spaces assessed for a one-year travel period. The investigation focuses on the enumeration of tri ps and unique locations visited over time which is employed as a straightforward way to reveal spatio-temporal patterns of travel behavior. It offers new insights into the nature of stab ility, innovation, and variety seeking in locational choice.
