Tetsudo Now is a real-time Google Map of the Japanese public transit network. The map simulates the current locations of buses and trains in Japan's largest towns and cities.
The position of the vehicles on the map are animated based on the transit timetables. Users can select which city's transit map they wish to view from a drop-down menu. They can also select the time of day they wish to see simulated on the map from another drop-down menu.
