📌 2026/07/15 Two research papers have been accepted for presentation at the 2026 IEEE International Conference on Intelligent Transportation Systems (IEEE ITSC 2026). The papers advance Data-driven intelligent transportation system : one presents a GPS-aligned framework for anomaly detection and localization in railway pantograph-catenary systems to support predictive railway maintenance. While the other introduces a privacy-preserving approach for inferring nationwide freight transportation topologies from large-scale expressway OD search data, enabling data-driven logistics and infrastructure planning.
