The author appreciates helpful comments from colleagues on early
versions of the tables and support from the NCDOT administration. The author also appreciates the engineers in North Carolina
and elsewhere who put their careers and reputations on the line
to get alternative designs built so that we might be able to develop
CMFs from them. The views and opinions in this paper are the
author's and do not necessarily represent the views, opinions,
policies, or practices of the NCDOT.

Joseph E. Hummer, P.E., Ph.D. (M) is the state traffic
management engineer with the North Carolina
Department of Transportation Mobility and Safety
Division. He specializes in alternative intersection and
interchange designs. Joe began researching the designs
in 1990, has published numerous articles about them, and has
invented several new designs. His two-part series in the ITE Journal
in 1998 helped create momentum in this area. He has a bachelor of
science and a master of science in civil engineering from Michigan
State University and a Ph.D. in civil engineering from Purdue
University. Joe is currently vice president of the North Carolina
Section of ITE.
