Samenvatting
This study investigated the effects of an analog versus an digital speedometer on driver performance. Younger and older drivers were asked to control the speed of a vehicle on a chassis dynamometer while detecting pedestrians moving out onto the simulated road of a filmed, computer-generated driving scene. For the speed control task, drivers were asked either to maintain a precise speed or to keep their speed within a 5 mph (8 kph) range. Drivers' speed control accuracy, ability to detect events on the roadway, and eye movement behaviour were measured. The results from this study indicated an advantage for the analog speedometer, but further research will be required in order to conclusively recommend one speedometer format over the other.
