COMPREHENSION OF VARIOUS TURN INDICATION SIGNS BY WHITE AND BLACK SOUTH AFRICAN DRIVERS

The NIPR was commissioned by the National Road Safety Council to determine the effectiveness of four different types of sign/robot combinations for possible use within the Johannesburg municipal area. The four types were: (1) a robot with direction information indicated by green arrows on the robot, (2) a robot with direction information given by a mandatory sign placed above it, (3) a robot with a prohibitory direction sign placed above it, (4) a robot with a prohibitory direction sign located next to the green light of the robot. Errors, reaction time, multiple responses and non-responses were monitored by a mini-computer. It was found that whites had no preference for mandatory or prohibitory direction signs as revealed by their turning errors, but they responded more rapidly to mandatory signs. Blacks, however, made fewer turning errors and also reacted more rapidly in response to mandatory signs. The opposite effect was observed with prohibitory signs. Recommendations are given. (TRRL)
