The Integrated Strategic Planning of Multimodal Freight Transport Network Under Infrastructure Budget Limitation

Abstract

Freight transportation has an essential role in connecting supply and demand that are spread geographically, which impacts the region's economic.In an archipelagic country like, Indonesia, freight transportation ideally involves more than one mode or multimodal transport.Currently, the development of transportation infrastructure networks is not yet integrated and lacks a multimodal perspective.Meanwhile, many stakeholders or actors involved in the freight transport sector also increase the complexity of multimodal network planning.From the government perspective, each transportation sub-sectors, primarily based on the mode, has its planning and lacks integration, particularly in multimodal transport.This paper proposes the integrated strategic planning model of a multimodal freight transport network.It emphasizes how to attain the optimum benefit which represents the efficient value in the freight transport system.The model's objective is to minimize the total distribution cost of the whole system by using the budget limitation of the transportation infrastructure's total investment, operational and maintenance cost.The budget limitation constraint indeed represents the role of the government to arrange the budget for the transportation sub-sector.The results showed that this model can select the best scenario of infrastructure development from the perspective of multimodal transport rather than unimodal.The proposed model can be used to integrate the planning of the transportation sub-sectors and, at the same time, develop more optimum multimodal transportation system.
