Towards reduction of right-turn accidents at intersections involving pedestrians, we investigated the influence of traffic environments on rightturn driving behavior. Aiming to apply the driving behavior indices, which we proposed in our previous study, to right turns at intersections on public roads, we investigated the relationship between the indices and traffic environment using Naturalistic Driving Study (NDS) data. Analysis results of NDS data revealed that presence of stop signs and traffic signals, width of both intersections’ entrance and exit roads and crossing angle of the intersection are traffic environment elements that need to be considered when assessing collision risk with the driving behavior indices.
