The Influence of Freight Generation Production Characteristics of the Internal – Regional Zone Commodities on Sustainable Freight Transportation Highway Network System

摘要

The increasing of commodity freights production in the internal – regional zone is a national development strategy to create interzone consolidation to accelerate the productivity of an internal – regional zone staple commodity. Sustainable freight transportation development requires a strategic direction based on the commodity freights production dominant characteristics in an internal-regional zone. This research has been done to estimate the distribution model and route assignment model of staple alternative commodity. Estimated generation production of commodity freights movement in production zones is influenced by zone demographic variables, infrastructure, and means of transportation. Gravity method is used to estimate the distribution model and route assignment model by calibrating it with Newton-Raphson method. The application and development of the gravity method in the modelling analysis will determine the estimation effect of sustainable freights transportation needed. The computational simulation result is an approach of mathematical model illustration for complex and systematic estimation. Therefore, the modelling results can provide the direction of sustainable highway construction on the highway network system, will determine the effectiveness and efficiency of traffic movement, and distribute the movement.
