Alabama Statewide Freight Study and Action Plan

The Alabama Statewide Freight Study and Action Plan was a study initiated by the Alabama Department of Transportation (ALDOT) recognizing the need for research in freight transportation. Research included identifying freight related constraints and how potential improvements to the State’s transportation system can facilitate freight mobility as well as the associated interrelationships between economic growth  Read more »

The Development of an Integrated Freight Planning Framework

Using national freight data at the local level is challenging due to the high level of aggregation, its proprietary nature and the need to apply proxy factors to allocate freight for system planning. Planning factors used in freight system analysis must be capable of describing the freight generation and attraction characteristics of the region. Employment  Read more »

An Approach to Collecting Local Freight Information

The use of local freight data in transportation planning is essential to ensure accuracy in the travel demand modeling process. However, unlike passenger transportation, where extensive research work has been performed into the collection and use of household travel data, limited research work has been performed to collect and use local freight travel data. This  Read more »

Developing Freight Analysis Zones at a State Level: A Cluster Analysis Approach

The ability to plan and forecast freight demand to support transportation infrastructure investment decisions is limited by the lack of available data at a level of detail that is meaningful to the transportation planner.  This paper develops an initial methodology for developing Freight Analysis Zones (FAZs) at a sub-state level to facilitate use of the  Read more »

Integration of A3 Thinking as an Academic Communication Standard

This paper discusses the integration of A3 Thinking as an innovative academic communication standard in industrial engineering. The paper begins by providing an overview comparison of A3 Thinking, a critical component in Toyota’s PDCA management system, and traditional academic course communication methods. The paper highlights key areas in academics where the use of A3 Thinking  Read more »

Modular Approach for Rapidly Developing Simulation Models for Analyzing and Evaluating Port Operations

This paper presents a modular approach for rapidly developing simulation models that can analyze and evaluate existing port operations, changes and expansions. Simulation is an inexpensive insurance against costly mistakes involving capital expenditures, but many managers still perceive simulation to be a costly and time consuming option. The underlying purpose of this research has been  Read more »

Transportation Infrastructure in Alabama: Finding and Filling the Holes

This research built upon previous work on the development of tools to bridge the gaps in the analysis and understanding of the relationships between economic growth and transportation infrastructure in Alabama. The tasks performed under this contract included: Development of the Integrated Freight Planning Framework including Trip Generation, Trip Distribution, Modal Split and Assignment and  Read more »

Using FAF2 Port Data to Model Freight in a Medium Sized Port City

The ability to accurately incorporate freight moving to and from a port into an urban model is difficult in both small and large cities.  To address this issue, this paper presents an application in which the Freight Analysis Framework Version 2.2 (FAF2) Port Data was incorporated into a traditional urban transportation planning model for a  Read more »

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 issues and problems associated with the use of such a highly aggregated database.  The UAHuntsville  Read more »

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 extensive consideration.  Additionally, since freight flow databases are generally large and highly aggregated, freight transportation  Read more »
