Issues and Approaches to the Utilization of Highly Aggregated Databases in Freight Planning and Modeling

As one of the four original pilot studies into disaggregation of the Freight Analysis Framework Version 2 program funded by the Federal Highway Administration, the research team at the University of Alabama in Huntsville (UAHuntsville) has experienced many of the...

Developing Validated Freight Transportation Models Utilizing Highly Aggregated Data

It is commonly accepted in the transportation planning community that local data is the only legitimate data that can be used to forecast travel.  Therefore, large, highly aggregated data sets are often discredited and deemed an inappropriate data source without...

Security Inspection Protocols: Impact on Container Terminal Throughput Using Simulation

This paper presents a simulation model to determine the impact of various container inspection protocols on the operation of a seaport container terminal. The inspection protocols are A) no inspection, B) container sampling with unloading and inspection coupled and C)...

Impact Analysis on Throughput on Air Fleet Resources Using Simulation

This paper presents a modeling approach to determine the impact on throughput on air fleet resources on the operation of airports. The primary constraints for this analysis are i) adherence to schedules, ii) optimization of resource utilization and iii) reduction of...

Conceptual Framework for Discrete Event Simulation of Interstate Traffic

This paper presents the development of a conceptual framework for simulating interstate traffic. ProcessModel was selected as the simulation package. The framework has been successfully used to model interstate I-65 from Montgomery to Birmingham, AL. The study...
