Transit directions for Taiwan have gone live in Apple Maps this week, helping users get from one point to another using the bus, subway, and other public transportations. 
All larger cities on the island seem to be covered, with even smaller ones offering transit directions.
Taiwan is the latest in a series of locations now offering transit directions, with cities like Paris, Detroit, New Orleans, and others recently being supported.
You can refer to Apple Maps Transit page for a more comprehensive list of cities offering transit directions around the globe.
