การวิเคราะห์ความเปราะบางของโครงข่ายทางรถไฟในประเทศไทย

Abstract

Rail transport plays an important role in driving society and the economy. However, disruptions on the railway network, especially natural disasters, remain a major obstacle to rail services. This article proposes a methodology for analysing the vulnerability of rail networks in the event of a flood. The method is developed based on a network flow-based model to predict the system performance during disruption and applies a Geographic Information System (GIS) to assess flood likelihood on the railway network. The study found that the top 10 most vulnerable railway links in Thailand are located in the central and upper central regions. Therefore, infrastructure managers and policy makers should particularly focus on these areas to create a suitable preventive strategy for enhancing the reliability and the resilience of the railway network in Thailand.
