This is part of a study dealing with the optional characteristics for greatest efficiency of highway signs. Because there is still considerable room for improvement in the legibility of signs and only a limited amount of experimental data available, this investigation was undertaken. This present project is based on work done before by Lauer, (1932) Aldrich, (1937) Forbes, (1939) and deals on the whole with the separate variables of letter legibility such as stroke, height-width ratio and spacing, each variable being isolated for experimentation. In this paper, however, the discussion will deal only with the isolation of the stroke as a factor in legibility.
