This project focused on forecasting freight logistics needs and developing and analyzing capacity plans for INDOT to consider. The forecast timeframe ranges from the 2020 to 2045; the commodities considered are those used in the FHWA framework. We considered five SSP (Shared Socio-Economic Pathways) scenarios that are in sync with those used by the IPCC (International Protocol for Climate Change). We also use the IPCC forecasts of world GDP and FHWA forecasts to develop county-level freight forecasts by commodity. A survey of industry participants, primarily in manufacturing, suggests that Indiana industries are tied to the rest of the country and the world for supply of inputs as well as for demand markets. Finally, we focus on three different industries—the recreational vehicle (RV) industry in Elkhart County, the furniture industry in Dubois County, and the Honda plant in Decatur County—to illustrate the impact of bill of materials and growth forecasts on forecasted congestion and potential capacity mitigation. Our results suggest that proactive capacity planning can enable INDOT to anticipate and ease congestion and ensure continued economic competitiveness for Indiana industries.
