DETERMINATION DEVICE, METHOD FOR DETERMINATION, AND PROGRAM

To appropriately predict a route of a vehicle when the vehicle is travelling at an intersection and determine the risk of the travelling.SOLUTION: The determination device determines the risk of travelling before a moving object turns right or left at an intersection. More specifically, the determination device acquires rate information on the moving rate of the moving object, and also intersection information including the shape of the intersection. After that, the determination device predicts a route on which the moving object travels at an intersection, based on the rate information and the intersection information so that the, so that the route includes a relaxation curve. The setting related to the relaxation curve is changed if necessary. The determination device determines the risks of travelling based on the route of travelling.SELECTED DRAWING: Figure 2 【課題】車両が交差点を走行する際の軌道を適切に予測し、走行リスクを判定する。【解決手段】判定装置は、移動体が交差点を実際に右左折走行する前に走行リスクを判定する。具体的に、判定装置は、移動体の移動速度に関する速度情報を取得するとともに、交差点の形状を含む交差点情報を取得する。次に、判定装置は、速度情報及び交差点情報に基づき、移動体が交差点を走行する際の走行軌道が緩和曲線を含むように予測する。この際、必要に応じて緩和曲線に係わる設定が変更される。そして、判定装置は、走行軌道に基づき走行リスクを判定する。【選択図】図２
