The present study is to evaluate drivers' evasive behavior focusing on the timing of visual perception for pedestrians when turning right at signalized intersections. The Virtual Reality headset-based Driving Simulator (VRDS) was used to measure drivers' timing of visual perception for pedestrians. As a result of experiments with 10 participants using VRDS, the drivers in the early timing to detect pedestrians can reduce the probability of severe conflicts with pedestrians. And when there were many pedestrians crossing at the time of conflict, it was difficult to detect early when drivers turned right at a gap. Based on the results of the eye measurement, we also proposed a safety level that evaluates the probability of conflict between a driver and a pedestrian. The proposed safety level was evaluated, and its validity was shown as an indicator to evaluate conflict probability. It was also suggested that for a more reliable safety level, time intervals should be included in addition to the results of eye measurement. Furthermore, we considered the timing and content of information provisions to avoid conflict with pedestrians when turning right.
