+  <h3>Transportation Routing Analysis Geographic Information System (TRAGIS)</h3>
+  <p>
+    <a href="https://tragis.ornl.gov/">TRAGIS</a> is developed by the
+    Geographic Information Science &amp; Tech Group at Oak Ridge
+    National Laboratory. From the abstract,
+  </p>
+
+  <blockquote>
+    <p>
+      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.
+    </p>
+  </blockquote>
+
+  <p>
+    It is of interest to us because it provides routing subject to
+    HAZMAT and many other restrictions. Essentially, one provides
+    TRAGIS with starting point <strong>A</strong> and an end point
+    <strong>B</strong>; it then calculates the best route between
+    <strong>A</strong> and <strong>B</strong>, subject to a number of
+    constraints.
+  </p>
+
+  <p>
+    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 <a
+    href="https://tragis.ornl.gov/TRAGISmanual.pdf">User Manual</a>
+    does provide some clues as to where they have obtained their data,
+    though.
