Abstract
Analysis of regional accessibility is very important in regional development, where good accessibility is needed to support regional development, especially for potential areas. In the accessibility analysis, it is necessary to have regional spatial data that shows the potential of the area, and accurate road network data including geometric and road network conditions required for accessibility calculations, in which the data derived from the road database were the main and accurate data source. Penukal Abab Lematang Ilir (PALI) is a new district in South Sumatra and has great plantations and mining potential. PALI District continues to develop its road network to improve regional accessibility. The road database for PALI District has been developed since 2017 and has complete road data covering162 roads with a total length of 555.85 km. This paper discusses the development of regional accessibility, through road improvement and road network development in PALI District using the existing spatial plan and road database. The calculation of accessibility was carried out using the principle of regional connectivity and considering the effect of distance and road network conditions. The network scenario was developed and the accessibility analysis provided the best road network development plan for the regional development of PALI District.
