One of the reasons for accidents occurring at unsignalized pedestrian crosswalks is that objects in the vicinity (visibility obstructions) are obstructing visibility between the driver and the people waiting to cross. Therefore, we quantitatively clarified the effects on visibility of the relationship between the location of visibility obstructions and the position of pedestrians waiting to cross by video observation. As a result, it was confirmed that the visibility between drivers and pedestrians waiting to cross was obstructed by the visibility obstacles. In particular, it was found that the distance at which a driver can see a pedestrian waiting to cross varies greatly depending on the location of visibility obstructions and the position of pedestrians waiting to cross. In order for drivers to be able to see waiting pedestrians from an appropriate distance, pedestrians need to be at least 1.8 m from the edge of the curb or at least 1.5 m to 2.3 m from the edge of the pedestrian crossing
