Why did transportation experts from around the world come to study Seoul's transit system? In this presentation-style episode, we break down four key innovations — the 2004 transit overhaul, integrated fares, the T-money card, and the TOPIS traffic information system — using real data from the World Bank and Korea's transport research institute. You'll also learn 10 practical Korean phrases for giving structured presentations, like "그렇다면 한 가지 질문이 생깁니다" (that raises a question) and "구체적인 사례를 하나 살펴보겠습니다" (let's look at a specific example). Perfect for learners who want to build presentation skills in Korean while learning something genuinely interesting.
