Reversible Lanes

This is another example of the need for Human Engineers in the Highway Department (see Entrance Ramp).  The reversible lane sign, showing a too small red “X” or a too small green “arrow”, was not designed by Human Engineers.  People are being killed because of a lack of Human Engineering knowledge.   The businesses and the public suffer further because of this lack of knowledge when the Highway Department eliminates the lane and erects a concrete barrier.

The “NO” letters should be 2 times the height of the “YES” letters.  The “NO” letters should be 2 times as wide as the “YES” letters. The “NO” word should be 2 times as wide as the “YES” word.  The lights in “NO” will be colored red and the lights in “YES” will be colored green.  Some of the lights in  “NO” will flash on and off.  The dashes are yellow - representing the lines of the reversible lane.

There are several cues to enable the driver to distinguish between the lanes: (1) language (2) height of letters (3) width of each letter, (4) width of the words, (5) the words have no common letters, (6) the “NO” flashes, and (7) the color of letters.
 
Forget the international marking, people are being killed and merchants are losing their livelihood.
