Description
In April 1980, the Minnesota Department of Transportation (Mn/DOT) issued a written policy requiring, in most cases, the use of red, yellow and green left turn arrow indications rather than programmed circular (ball) indications for left turn signals. Contracts let since 1981 have specified 12" red, yellow and green arrows for exclusive left turn phasing.
In spite of the apparent success of arrow indications, there remains some non-uniformity of use and debate over the merits of the red arrow and the red ball. This present study, therefore, addresses the use, safety and acceptance of red arrow indications.
