Analysis of Regional Growth Through Road Networks Index: Evidence from Ternate City

Regional growth is a complex phenomenon influenced by the interaction of physical, social, and economic factors, with transportation infrastructure serving as a key component in supporting this dynamic. This study aims to analyze the correlation between road network connectivity indices and regional growth on Ternate Island, North Maluku Province, Indonesia. Using spatial data and a Geographic Information System (GIS) approach, the study calculates the Alpha, Beta, Gamma, and Eta indices, as well as road network density, across five districts on Ternate Island. Regional growth indicators analyzed include per capita income, population density, and the availability of basic infrastructure. Pearson correlation results show that the Beta index and road network density have a very strong relationship with regional growth parameters, while the Alpha index shows a moderate relationship, and the Gamma index has a weak correlation. The Eta index demonstrates a significant negative relationship, indicating that the longer the average road segment, the lower the efficiency of connectivity. These findings suggest that a dense and functionally connected road network plays a crucial role in supporting inclusive and sustainable regional growth. Therefore, regional development strategies, particularly in island regions, should consider road connectivity as a primary instrument in infrastructure planning.
