Abstract
The Evolution of TRAGIS Track: Transportation Author(s): Mark Tuttle Originally developed for the U.S. Department of Energy, the Transportation Routing Analysis Geographic Information System (TRAGIS) is a client-server routing model built on the MapObjects platform. Since its original release in 1995, functionality has included highway, railway, and waterway routing. Most recently, ORNLs LandScan USA Interim population data has been integrated with the transportation networks. This paper will provide insight into the TRAGIS development cycle including an overview of the current functionality, the technical architecture of the application and, most important, current development activities and future directions of TRAGIS evolution. Development involves adding multimodal routing capabilities for rail-to-highway, water-to-railway, and rail-highway-waterway activities. Functionality to permit time-distance modeling is being developed. Significant improvements to the graphic display of results are being included, and a stand-alone version will be an option.
