Therefore, Counter Crossing Collisions have many occurs on the crosswalk has become an issue of traffic safety. And so, this study Cause of the accident in crosswalk on the left turn channel analyzed focus on relationship of sudden braking behavior of drivers and behavior of bicycle, bicycle speed, bicycle position. As a result of this study, We indicated quantitatively that breaking behavior of driver are influenced by the behavior of bicycle approaching to the crosswalk.
