A few examples of time schedules I did over the years. Looks simple, but you have to create a sophisticated typographical system if you dont want to navigate into a dead end.
Even for the big ones, the posters fort stations, with so many different signs and symbols in a row, I was strongly recommende to create a suitable font only for this purpose! My students today would become desperate on this complex task!
For the first covers of time schedules from 1994 I made the fotos myself.
