Infrastructure Development of Road Network for Regional Development Based on Accessibility Concept

Abstract

Penukal Abab Lematang Ilir (PALI) District is a new district in South Sumatera Province, Indonesia which has been established since 2013 and has five subdistricts and 72 villages. PALI district continuously implements regional development to improve the living standard and economy of the community. Consequently, the infrastructure development of road network based on needs of improvement of accessibility and the spatial area is a precondition for economic and regional development and improvement of competitiveness of PALI district in South Sumatera Province. This research aimed to study the needs of infrastructure development of road network in PALI District regarding the economic and regional development and other sectors based on accessibility measurement. The data of existing infrastructure and regional condition and spatial area plan are activity centres, spatial patterns, and strategic area to be fundamental in determining the infrastructure development of road network for either internal or external accessibility of PALI District area. The existing condition based on the accessibility values show that several villages which are the priority of development have low accessibility so that the development of road infrastructure networks is needed. The simulation of scenarios of road network development was conducted to get the best accessibility score in order to support the plan of the existing economic and regional development. The result of the study is the plan of infrastructure development of road network of PALI District that can really support economic growth and regional development in PALI District.
