The distribution of road transport goods has the characteristics determined from the commodity and supply chain system of the commodity to be transported. Leading export commodities have an important role in regional economic growth and the drivers of national economic stability. Coffee commodity is one of the main export commodities that have significant economic value in international trade. To support the economic value of better coffee commodities, a more efficient distribution system is needed from the distribution system of coffee commodity production and trade in the coffee commodity production zone to the destination zone. The revenues of coffee commodities are estimated to be based on demographic variables, the condition of road infrastructure and transport vehicles. Production zones of coffee commodity crops have characteristics that develop according to the condition of road infrastructure in the zone. Interactions between production zones use gravity modeling with the loading of transport networks based on the goods traffic in accordance with the dominant characteristics used in transporting the commodities. The development of a freight transportation distribution model with the Breadth-First Search algorithm has the objective to consolidate the interaction of goods transport supply and demand within a zone to determine the efficiency of the traffic load on the road network system. So that the time of coffee commodities distribution will be faster in the destination zone in accordance with the volume of commodity production and the number of available transport vehicles.
