Abstract Driving on the curved road is a common task that many drivers routinely performed, but there is an underlying impact on driver behavior and vehicle maneuverability. Previous studies have shown that driving performance (speed and acceleration) and visual performance (gaze and Useful Field of View (UFOV)), can be critical components of curve analysis. However, with the change of road conditions, there are increasing safety concerns for the driving environment required to determine vehicle safety maneuverability. In this study, we examined how different curved roads influence concurrent-driver driving behavior and vehicle maneuvering performance along a simulated continuously curved road. Twenty-eight participants of different ages and occupations were invited to participate. A structural equation model was established to represent how the road geometry influences driving performance and vehicle maneuverability. The results showed that there are clear differences in driving behavior and vehicle maneuvering performance between the curved road groups. Driver will suffer a more complex driving environment, and must observe more objects, which will result in increasing lane position errors, gazing, and workload, while decreasing speed, acceleration and UFOV.
