This dataset contains the instance data and computational result files used in the study “Rendezvous-Based Relief Delivery on Road Networks with Vehicle-Dependent Accessibility”. The archive includes generated network instance files, demand information, vehicle and transportation-mode information, road-accessibility information, and computational results supporting the numerical experiments reported in the paper. The original road-network data were obtained from OpenStreetMap. The source code is not included in this dataset and will be released separately after publication.
