There are many studies of considering the behavior of the merging vehicle aroundthe joint department of highways. However, the merging vehicle and the vehicle on the main lane of the highway interact, and the behavior of the vehicle on the main lane, especially its giveway behavior, should be analyzed. Therefore, we investigate the data of giveway behavior by the digital video camera, identify thefactors that affect the giveway using the theory of quantification II, and examine the properties of the giveway behavior.
