Decision-making regarding logistics and supply chain need to be based on freight transportation modeling, but most of transportation models only consider passenger travel demand. An integrated land use transport model is introduced here which addresses both freight and passenger demand modeling. The framework is called PECAS, which stands for Production, Exchange, Commodity Allocation Syslem. PECAS consists of the following three modules: Activity Allocation (AA), Space Development (SD) and Transport Supply (TS) and is linked to an aspatial regional economic model. The focus of this paper is to illustrate the capability of its AA module in modeling logistics and supply chains, for which the major economic sectors are considered and the flows of all commodities, including goods, service, space, land and labor, are simultaneously determined from production zones to exchange zones to consumption zones. This paper gives a brief introduction to the framework and presents detailed methodologies used in determining the locations of activities and exchanges between them.
