The table presents an example dataset that demonstrates the structure from which Networks of types I through V can be constructed. This particular dataset form contains information on subjects and their travel patterns. The five networks represent the types that can be built from the dataset. Types of networks: Network I – original path of travel, II – links with home locations used as origin points, III – home to work links, IV – temporal links with each point in the original path creating a new origin point, and V – temporal links based upon time periods with home locations used as origin points. Note that the node labels “H”, “W”, “P₁”, and “P₂” correspond to the locations Home, Work, Point 1 and Point 2, respectively, in the table.
