The Web-Based Transportation Routing Analysis Geographic Information System (WebTRAGIS) model is a geographic information system tool for modeling transportation routing. WebTRAGIS is deployed as a browser-based application interface, and the routing engine is located on a server at Oak Ridge National Laboratory (ORNL). WebTRAGIS offers users numerous options for route calculation using uniquely value-added network databases for highway, rail, and waterway infrastructures in the continental United States. The model also provides reporting information on population counts for all transportation segments using the LandScan USA population distribution data model.
