In this study, we demonstrated that the size of a preceding vehicle affects the behavior of the following driver. Intelligent assistance systems, including autonomous driving, have been considered in the prevention of traffic accidents. If forecasting future actions of surrounding vehicles is possible, driving safety can be significantly improved. Therefore, our research group developed a prediction system. Previous studies reported on the effect of the size of the preceding vehicle on the driving behaviors of the following vehicle. However, the effect on the lane changes of the following vehicle has not yet been discussed. This paper analyzes the effect of the size of the preceding vehicle, particularly focusing on lane changes. It is demonstrated that drivers frequently change lanes when a large vehicle is ahead compared with when a normal-sized vehicle is ahead. In addition, the model of lane-change detection considering the size of the preceding vehicle was constructed using actual traffic data. Based on a comparison with a conventional model, our approach proved to be capable of improving early detection performance.
