Driving a motor vehicle is a common practice for many individuals. Although driving becomes repetitive and a very habitual task, errors can occur that lead to accidents. One factor that can be a cause for such errors is a lapse in attention or a failure to notice critical information. When driving, individuals must not only attend to the other moving vehicles, but they must also remain aware of and detect critical information that is in the surrounding environment. As the environment becomes more complex however, the ease of detecting these critical targets becomes hindered. Because of these failures in attention, this research focuses not only on the visual complexity of the environment but also on the dynamic relation of the moving vehicles on attention. By incorporating a dual task paradigm of vehicle tracking and target detection in a visually complex environment, a direct examination for the influence of outside vehicle factors on a driver's ability to detect critical targets was measured. Furthermore, driver reactions such as brake onset, steering deviations, and changes in velocity were examined. This research found that overall improvements in driver reactions are observed when the environment has low clutter and there were fewer vehicles to be tracked. |
