Modeling Origin Destination Matrix in the Inter Island Cluster of North Liukang Using Gravity Model

Abstract

Trip Distribution is one of the step in the Four-Step Transportation Planning Model. The modelling of inter-zone trip patterns considered several things as the effect of the inter-zone accessibility network system level as well as each-zone production and attraction level. The trip distribution model that used in this study is gravity model (GR) which is classified in synthetic method group. The aims of this study is to estimate the distribution trip model into origin-destination matrix form in both the passengers and cargo trip flow at archipelago North Liukang Tupabbiring sub-district region, Pangkep Regency, South Sulawesi. Determination the number of trip is using Production Constraint Gravity Models with exponential barrier function to estimate inter-island traffic distance. The results showed that the total number of passenger trip from the urban capital to Pangkajene Regency was around 137 passengers per day and the inter-island trip was around 41 passengers per day while the total of cargo trip from the capital sub-district to the city of Pangkajene was around 0.96 tons per day and the inter-islands trip was around 0.28 tons. The result of this distribution trip matrix will be used as a basis for capacity planning of inter-island passenger transport fleets in the North Liukang Tupabbiring sub-district.
