11. Forecasting Freight OD Flows
- Factor an existing OD trip table of commodity flows to
estimate future flows
- The distribution step in a 4-step model
Transportation Demand Analysis - Freight Demand Analysis
- Trace the flows commodities between economic sectors
and between zones

12. Growth Factors Supply and Demand from a zone are predicted using
Iterative Proportional Fitting (IPF) technique is used
