What is the Freight / Fuel Transportation Optimization Tool?
Flexible scenario-testing tool designed to analyze future fuel scenarios for various commodities, datasets, and assumptions
Optimizes routing and flows at scenario level using a Geographic Information System (GIS) module and an optimization module
Multimodal network: road, rail, waterway, pipeline, intermodal facilities
Outputs of optimized scenarios:
material/commodity flows costs CO2 emissions fuel burn number of vehicle trips distance, vehicle miles traveled

Analysis Steps
4
Set Origins and Ultimate Destinations
• • • •
.
Example: waste feedstocks across U.S. Example origins located at county population centroid (can also be points or gridded data) Raw material travel over network can be limited or not Tool can track multiple products (e.g., diesel and jet fuel, etc.) and processing types (e.g., crushers, biorefineries, etc.)

5
Locate Potential Processing Points
.
• •
Can incorporate existing facilities Tool can generate potential candidate processing points based on crop availability and minimum aggregation threshold along the transportation network “en route” to destinations
Example Results – Do Not Distribute or Cite
6
Identify Best Routes
.
Based on: • Transportation costs by mode • Transloading costs • Weightings and penalties (e.g., prefer interstates over smaller roads) • Capex if want to “build” new processing locations.

Optimize Movements: Feedstock-to-Processor Routes
. Initial routes from raw material origin(as if it were all converted to fuel) to destinations are shown.
• • • •
Minimizes overall scenario “cost” Selects among origins, processing points, destinations Provides optimal flows by mode in the final optimal solution Note that some modal movements may be obscured by others (e.g., rail routes may parallel and cover roadway routes)
