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...

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...

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...

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...
