Outline of Presentation What is TRAGIS? Accessing TRAGIS TRAGIS Networks TRAGIS Features Recent Developments Future Directions 2
What is TRAGIS? The Transportation Routing Analysis Geographic Information System (TRAGIS) model is a powerful routing and GIS analysis tool developed for DOE The model has two parts WebTRAGIS client software TRAGIS server web server at ORNL Replaced the legacy HIGHWAY and INTERLINE models over 5 years ago 3
TRAGIS Model Includes routings networks for Rail Truck Barge Model provides population information for risk assessment Used to identify legally compliant routes 4
How does TRAGIS work? WebTRAGIS software on user s PC is used to select routing parameters Information is sent over the Internet to the TRAGIS routing engine on central server Results are quickly returned to user s PC for display Routing networks on central server minimizes updates and ensures that all users access the most recent database 5
TRAGIS Funding TRAGIS is primarily funded by DOE EM-11 Office of Transportation Ongoing site transportation activities Cleanup activities at DOE sites Routing of high visibility shipments Spent nuclear fuel (SNF) Transuranic (TRU) nuclear waste Foreign research reactor SNF RW-30 Office of Nuclear Transportation Planning activities for the Yucca Mountain Repository 6

TRAGIS User Base Currently over 235 registered users Federal Users (largest groups) DOE DOT DOD NRC National Laboratories Federal Contractors/Subcontractors State/Regional/Tribal 9
TRAGIS Highway Routing Many commercial software packages and web applications are useful for planning trips Such routing tools are not suitable for planning HRCQ shipments because of the need to meet USDOT routing regulations Trucking firms may not select routes compliant with USDOT regulations for radioactive materials Model also includes HazMat restrictions 10
Why Use TRAGIS for Truck Routes? TRAGIS calculates truck route to comply with USDOT HRCQ regulations (49 CFR 397.101) Highway network is: 1:100,000-scale database Frequently revised to maintain up-to-date information Includes all nuclear sites (commercial reactors, research reactors, DOE sites) 11
TRAGIS HazMat Routing FMCSA maintains a list of designated, preferred, and restricted routes These HazMat restrictions included in TRAGIS highway network Activate by checking HazMat constraint 12
TRAGIS Highway Route Types Standard Quickest (minimize driving time) Shortest (minimize driving distance) Commercial (70/30 split between time/distance) Other (user defined ratio) Special HRCQ (follows USDOT regulations) HRCQ with Nevada access roads (to match Yucca Mtn FEIS analysis) WIPP (NM designated routes) 13
USDOT HRCQ Routing Requirements Shortest distance from origin to preferred highway entrance Minimize driving time on preferred network Use Interstate bypasses/beltways around cities Shortest distance from preferred highway exit to destination States can designate preferred routes in addition or in lieu of Interstate highways 14
HRCQ Routing Formulation i ( a D bt )c i i L = Min + D i, distance of segment i in miles T i, travel time of segment i in minutes a, 0.0 for preferred route, else to 1.0 b, 1.0 for preferred route, else to 0.0 c i, 1.0 for preferred route, else to 30.0 i 15
HRCQ Route between New York City and Los Angeles Estimated travel time: 49 hours, 50 minutes Distance: 2,953.8 miles Population within ½ mile either side of route: 1,496,672 16
Rail Routing is Different than Truck No single railroad provides service across the U.S. unlike highways where many trucking companies serve the entire country Railroad corporations own their right-of-way trucks operate over public highways Four major U.S., two Canadian, and over 500 regional and short line railroads in the country In the east: CSXT & NS In the west: BNSF & UP In central US: CN & CP 17
TRAGIS Rail Routing TRAGIS calculates routes that reflect current rail shipping patterns Based on traffic density Includes consideration of interchange locations between rail companies Rail network is: 1:100,000-scale database Developed for DPO-MA at Dahlgren NSWC Includes rail lines to nuclear sites with rail access Frequently updated to reflect current ownership, trackage rights, and attribute information 18
Common Question about Rail Routing Is track class in the network? Answer is No for the following reasons Track class can be dynamic A line may have several sections of different track classes due to grade, curvature, bridges, etc. This complicates the use of track class as a routing criteria High volume rail lines have the better track (higher track class) and TRAGIS maximizes the use of such lines At a recent meeting with railroad companies, they suggested that track class should be considered as an attribute 19
TRAGIS Rail Routing Formulation L i o i = originating railroad for link i 0.8 for the originating railroad 1.0 for all other railroads f i = mainline classification 1.0 for A-mainline 1.2 for B-mainline 1.9 for A-branchline 4.0 for B-branchline ( o f d ) + ( T ) i i n = Min i n d i = distance for link i, in miles T n = transfer penalty at node n 300 units for primary transfer 400 units for minor transfer 151 units for terminal railroads 1500 units for detour transfers 20
Rail Route between New York City and Los Angeles Distance: 3,126.2 miles Estimated travel time: approximately 130 hours Railroads: CSX Transportation, Indiana Harbor Belt, BNSF Population within ½ mile either side of route: 1,710,639 21
TRAGIS Barge Routing Waterway network includes inland, coastal, and deep water channels Nuclear sites with possible barge facilities are included in the network Port facilities are in the network 22
Barge Route between Pittsburgh and New Orleans Distance: 1,761.4 miles Estimated travel time: approximately 8 days Population within ½ mile either side of route: 401,700 23
TRAGIS Routing Features Automatic alternative route calculation Ability to temporarily modify the routing network by blocking Nodes Links States Railroad companies The blocking feature is useful for analysis of Infrastructure damage or repair Temporary traffic delays User assisted alternative routing 24
TRAGIS Route Listing Features Model generates a listing that provides a description of the route and summary information Table of tribal lands and mileage through tribal lands is provided Population information provided as: Table of population density by state Summary information for input to RADTRAN model Population count for three buffer widths either side of the entire route and by state 400 m 800 m 2500 m 25
TRAGIS Mapping Features Map of route can be displayed by two methods Quickest is straight line segments Actual shape file of route takes a minute to process Background data provided Respective transportation network Census urbanized areas Native American tribal lands User provided shape files can be added to map Maps can be Saved as ESRI shape files or as bitmap files Included in reports as color graphic images Printed 26
Population Data in TRAGIS Based on LandScan USA Interim 15 arcsecond (450 m) grid cell database Uses 2000 Census data LandScan model distributes population based on factors such as Census geographic areas Proximity to roads Land use data Slope of land surface 27
Example of population data and buffer 28
Recent Developments Major update to rail network underway Federal Railroad Administration is providing funding to ORNL Add FRA specific enhancements To improve GIS capabilities Work is underway to add intermodal capability to the model Truck/Rail Rail/Water Truck/Water 29
Future Directions TRAGIS is has a client/server architecture PC-only based architecture could be useful for use in remote or on-the-road locations without Internet access 30
Conclusion TRAGIS provides Up-to-date transportation networks for routing analysis Easy access via the Internet Detailed population data adjacent to transportation networks Integrated visualization capabilities 31
