There is a parallel evolution of a political economy and the transportation system either in developed or developing countries. The growth of economic will increase the number of ton-km of freight transportation. As flows of freight and their impacts increase, transportation planners, managers, and operators have a more concern to develop a better methods for tracking and monitoring the flows of commodities and analyzing the impacts of these flows to the transportation infrastructures. Current estimation of freight flows and analysis methods have several problems, which are related to the data and the method itself. This paper attempts to elaborate the relationship of the economics activities of commodities toward export -specifically the production of goods and services that generate freight transportation, the spatial data of commodities related to the economics' activities (resources, factories, and outlets), the transportation data (infrastructures, modes, and services), and government regulations, in formulating the method for freight transportation planning to produce an efficient freight movement to enhance sustainable mobility and economic development in the regional scale.
