The Transportation Routing Analysis Geographic Information System (TRAGIS) is a powerful routing analysis tool that combines graphical interfaces with an extensive highway, rail, and waterway database. TRAGIS operates over the Internet and can supply users with a variety of information about routes.

Similar models developed by TTG include HIGHWAY and INTERLINE.
