EFFECTS OF AN IN-VEHICLE DISTRACTOR UPON DRIVER PERFORMANCE

This paper reports the effects of the presence of an in-vehicle distractor (simulated cellular phone) on driver performance at a light-controlled stop. Ten subjects completed 60 laps on a closed test track. On 15 laps neither a distractor nor a traffic control device were activated. On 5 laps either the distractor or the light-control device was activated. This sequence was repeated at a low speed and a high speed. The overall results of the experiment provide a consistent portraiture of driver response in the presence of an in-vehicle distraction. Evidence indicates that drivers register the change of the light status more slowly in the presence of the distractor as indicated by the increased mean and variability of brake response time. Having registered this change, drivers respond with more intense braking which results in reduced stopping time, however, this response is much less consistent with no distractor.
