Simulating the Impact of Increased Truck Traffic through a Tunnel Crossing Mobile River

This paper presents the development of a simulation model to evaluate the impact of increased 18-wheel truck traffic on the I-10 tunnel crossing the Mobile River in downtown Mobile, Alabama. The increased truck traffic is resulting from overall globalization of...

A Methodology to Use FAF2 Data to Forecast External-External Trips

Simulating freight activity in a statewide model requires the development of an origin/destination matrix containing internal-internal trips, internal-external and external-internal trips, and external-external trips.  The external-external trips are often difficult...

Using a Gravity Distribution Model and Discrete Event Simulation to Enhance Freight Planning

Freight analysis and planning has lagged behind traditional transportation planning and is often neglected in models following the four-step process.  National projections are that freight shipments will double in the next decade.  In Alabama, manufacturing growth and...

Using a Federal Database and New Factors for Disaggregation of Freight to a Local Level

Transport professionals at the local level often have difficulty incorporating freight into transport models and plans because freight data is proprietary at local levels requiring extensive aggregation to national levels before being released to the public. ...

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...
