Abstract
The study conducted a simulated driving experiment to explore the impact of visibility and warning types in connected environment on driving performance, eye movement, and brain activity. Twenty-four drivers participated the experiment. A rural two-way two lanes highway was designed as the roadway environment. Data were aggregated from different scenarios (4 (visibility: clear, low fog, medium fog, night) × 3 (warning types: no warning, visual warning, and visual with audio warning). All Participants must perform both car-following and lane-changing driving tasks in each drive. The experimental results show that the usage of different warning types under different visibility conditions in the connected environment has a significant impact on the driving performance and traffic safety. The findings have important implications for the application of the connected environment and the choice of different warning types.
