Drivers often perform tasks alone or in combination that don't relate to control of their vehicle. This experiment
evaluates the impact on simulated driving of performing non-driving tasks.
The results showed that some of these tasks significantly degraded driving performance. The task that required
drivers to use the map device caused the greatest problem. In addition, older drivers performed less well than younger
drivers. The study shows objective reasons for evaluating the trade-offs between maximizing traffic safety and
providing drivers with information that requires a high degree of visual attention.
In the experiment, drivers performed the following secondary tasks alone, as pairs, or all three simultaneously:
talking on a simulated cellular telephone, finding an object in an enclosed container, and using a special radio with
head-up map and text displays. The experiment required drivers to maintain speeds of 25 to 30 miles per hour, keep
the car centered in their traffic lane, and respond quickly to the appearance of simulated brake lights. Researchers
divided subjects into four groups of 10 members each: young females and males with an average age of 31 and older
females and males with an average age of 70.
