Following the signs – English road hieroglyphs?

Extract

ON MY OFFICE wall I have a Japanese Sumo Wrestling Calendar, a gift from a kind student. The name of the calendar is in kanji followed by the word CALENDAR in gold capitals and the year in numerals, 2003, in red. The numbers of the months are also in red and the same size. The names of the months are in English in a smaller font, January, February, … The names of the days of the week are in kanji. The character for Sunday and the date numbers of Sundays and holidays are in red, the other days and dates in black numerals. Of course, careful design has gone into the calendar, but one is struck by the plethora of visual communication systems involved.
