There are limitations in preventing sporadic railway failures and accidents caused by various reasons with existing safety management technologies. Recently, Korea has planned to develop new technology using the rapidly developing fourth industrial technology such as ICT, IoT, Big Data, and AI. In this paper, we would like to introduce the following data-based smart railway safety technologies that have promoted in Korea; 1. IoT-based railway site safety big data construction and smart preemptive response technology, 2. AI-based railway operation safety analysis, prediction, and decision-making technology, 3. Big data-based integrated railway safety management system technology. We would like to introduce Korea’s safety plan.
