Abstract

The young driver problem requires remedial measures against speeding and overconfidence. Previous research has shown that increasing the task difficulty during training can enhance subsequent retention performance and prevent overconfidence. In this driving simulator study, we evaluated the training effectiveness of vertical field of view restriction during a self-paced lane-keeping task. Sixty-two young, inexperienced drivers were divided into three groups: a near view (NV) group (upper part of the screen was blanked), a far view (FV) group (lower part of the screen was blanked), and a control group driving with full sight. All groups drove three training sessions lasting 8 min each on a curved rural road, followed by two retention sessions with full sight. The first retention session took place on the same rural road and the second session on a highway. Compared to the control group, the NV group drove with lower mean speed and had more road departures during training. Furthermore, NV drivers reported significantly lower confidence during the training sessions and the second retention session. NV drivers directed their eye gaze more closely to the vehicle during training and both retention sessions. FV drivers approached corners with lower speed compared to the control group during training and had a higher number of rapid steering wheel turns during training and both retention sessions. In conclusion, removing visual information resulted in lower reported self-confidence (NV) and altered steering behavior (FV) in retention sessions compared to driving with full sight. Furthermore, NV training caused drivers to direct their gaze closely to the vehicle during retention, which may be negative for road safety. Possible effects of simulator-based driver training on eye-scanning and safety are discussed.
