Committees are limited by TRB to 25 members including
the chairman. The only exception to this is that a committee may include
as many as four non-North American members above the 25 member limit. To
assure that the committee is open and affords an oppotunity to those who
are excluded by the membership limit an ability to participate, we maintain
a "Friends of the Committee" group. "Friends" are welcomed to attend committee
meetings, participate in our activities, serve as subcommittee members,
offer and review papers and in any other ways demonstrate their willingness
to contribute to the committee. If you are interested in being added
to our ever-growing list of "Friends" contact our secretary by
voice or by email.
