Timetable
Timetables are commonly used for buses and trains, we begun with simple print media timetables, and you can still see them on some of the bus stops in a small time but now days, you can also see timetables like this one we can see on the left,the electric board is much more useful from the paper timetable as those are real time programed, whenever a bus/train is delete or just late few minutes you can easily read and the updates are really reliable. You can’t really tell from the printed timetables whether the bus is late or have you been late and now you have to wait for the next one. This is an easy example to show how the technology has moved over few years.
