Development of a Freight Database for Use in Allocating Freight Traffic to Sub-State Traffic Zones

The use of national freight data at the local level is challenging due to the high level of aggregation and because freight data is proprietary.  Many national freight databases aggregate information to the individual states or major communities.  Most methods of...

Using a Federal Database and Local Industry Sector Knowledge to Develop Future Freight Forecasts

In smaller urban areas, freight transportation is often not explicitly modeled, but is included implicitly as a percentage of non-home-based trips, which has nothing to do with the actual behavior of freight. This incorporation has the potential to develop future...

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...
