Example
30 ft
sign with 6 words
An exit ramp sign with 6 words, located 30 ft away (to the
side) from the driver path.
Given: Design acuity = 20/40, Design speed = 55mph.
Acuity = 20/40 means people can read 1/3" letters 10 ft away
Questions: We design on the safe side (Driver should read the
sign with fairly clear vision) :
(1) How far from the exit should the sign be located?
(2) What letter's height should we use in the sign?
