Dear Dr. Mike and All Others;
The article reminded me of the article I sent to the LPSF group and I found it again from Dec. of 2004.

The experiment and the reasons for it are laid out. Read it over again as it does provide the basis for the new way of doing traffic today that everyone is oohing and aaahhhing over - no traffic signs.
