A Demand Model for Intermodal Travel in the State of Alabama

This research features the development of a transportation model that accurately shows the current state of Alabama’s infrastructure and allows for predictive analysis of the impact that relocating or developing industries would have on the local areas. A survey was conducted to determine freight volume and movement for a select group of industries. Data from published government sources were also used. Regression analysis was performed to study the relationships between industry size and type and the volume of freight that moves using different modes of transportation. A descriptive model was developed using TRANPLAN that can be used to determine the expected effect of a new business on the local transportation infrastructure. This information can be used by agencies to identify target industries that can promote economic growth while have little negative effect on congestion or requiring significant infrastructure improvements
