Abstract

A total of 123 motorists participated in the study, with 23 to 73 motorists viewing each signal. The study indicated that most of the signals which involved the use of a STOP-SLOW sign paddle and/or hand motion were understood by the drivers. The signals in which a flag alone was used were less effective. Some of the signals evaluated were found to be inadequate with respect to driver understanding, especially those signals intended to alert and slow motorists.
