Post-Disaster Restoration of Road Network: An Empirical Assessment Using Digital Trace Data from Flood and Landslide Events in Aceh, Indonesia

This repository contains the supplemental algorithmic documentation and analysis code accompanying the manuscript "Post-Disaster Restoration of Road Network: An Empirical Assessment Using Digital Trace Data from Flood and Landslide Events in Aceh, Indonesia," Contents: Supplementary_Material.docx — Full pseudocode for Algorithms S1–S4: Algorithm S1: Automated online news scraping and filtering pipeline (search-based retrieval, language/date/location/relevance filtering). Algorithm S2: Sentiment analysis procedure using IndoBERT with rule-based adjustment for disaster-context terms. Algorithm S3: Kaplan–Meier estimation and pairwise log-rank testing procedure for restoration duration by asset subtype. Algorithm S4: Cox proportional hazards regression procedure (univariate and multivariate specifications, ridge penalization, model diagnostics, and proportional-hazards assumption checks).
