The Effect of Heavy Goods Vehicles on Drivers’ Visual Behaviours

It is believed that heavy goods vehicles (HGVs) have some specific effects on the drivers of following vehicles in terms of obscured vision and psychological pressure. As an indicator for both drivers’ vision impacted by external reasons (e.g. environmental changes) and their demands influenced by internal factors (e.g. psychological pressure), drivers’ visual behaviors in following HGVs compared with following passenger cars were investigated in this paper. The experimental results show that when following HGVs, drivers tended to have a higher saccade (rapid eye-movement) percentage, higher deviation on horizontal gaze angle, and more gaze on the mirrors. The results confirm that drivers had different visual behavior and employed different information extracting strategies when following HGVs. These findings provide better understanding of driving behavior difference in terms of leading vehicle type.
