Transportation Routing Analysis Geographic Information System (TRAGIS)

+

+ TRAGIS is developed by the + Geographic Information Science & Tech Group at Oak Ridge + National Laboratory. From the abstract, +

+ +
+

+ The Transportation Routing Analysis Geographic Information + System (TRAGIS) model is used to calculate highway, rail, or + waterway routes within the United States. TRAGIS is a + client-server application with the user interface and map data + files residing on the user’s personal computer and the routing + engine and network data files on a network server. The user’s + manual provides documentation on installation and the use of the + many features of the model. +

+
+ +

+ It is of interest to us because it provides routing subject to + HAZMAT and many other restrictions. Essentially, one provides + TRAGIS with starting point A and an end point + B; it then calculates the best route between + A and B, subject to a number of + constraints. +

+ +

+ Unfortunately, TRAGIS is a client/server application. Most of the + interesting logic and data are stored on the server, to which we + don't have access. The User Manual + does provide some clues as to where they have obtained their data, + though. +
