Business and community leaders, as well as public sector officials, recognized that the effective and efficient movement of freight is key to a region’s economic competitiveness. Using almost any metric, freight traffic is growing faster than passenger travel. Freight, by it nature, crosses modal boundaries, therefore any analysis method that does not consider multiple modes of transportation, such as truck and rail, are inadequate. However, by better understanding freight needs and issues, it is possible to design and conduct an economical and efficient freight planning process that can be integrated with conventional transportation planning. More than 15 billion tons of freight valued at over $9 trillion traveled on the US transportation infrastructure in 1998. By 2020, freight will have grown by nearly 70 percent and the value of the goods moved will be almost $30 trillion, according to the Federal Highway Administration. This level of activity and growth demands the attention of transportation system planners. Freight data is key to making informed decisions on infrastructure investment and policies issues that affect the effectiveness and efficiency of the freight transportation system. Freight data is critical to the evaluation of options to mitigate congestion, improve economic competitiveness, facilitate the effective use of land planning, optimization of modal activity, improve safety and security, reduce fuel consumption and enhance air quality. Although data by itself does not ensure good decision-making, it is not possible to make informed decisions without valid data. A Transportation Research Board committee formed to investigate and make recommendations on freight data concluded that the present patchwork of uncoordinated and incomplete freight data sources should be reengineered in the context of a national freight data framework that provides for a more integrated approach to freight data collection and synthesis. The committee noted that this would be a multi-year effort and would involve many technical organizational challenges. In response to this need to investigate freight from a multi-modal and comprehensive perspective, researchers at the University of Alabama in Huntsville (UAH) developed a Freight Planning Framework (FPF) shown in Figure ES.1. This framework is a direct freight forecast based upon industry economic activity that offers an improvement to the forecast based upon a percentage of overall traffic flow typically used by transportation planners throughout the U.S. The project research goal was to establish
