PROBLEM TO BE SOLVED: To reduce labor required to monitor motion of a mobile body passing an intersection.SOLUTION: A terminal device 12 receives moving image data from an imaging device 11 installed at an intersection 5, receives aspect state data indicating the aspect state of a traffic signal 6 and a traffic signal 7 from a signal control device 8, and generates locus data indicating motion of a mobile body that the moving image data shows for each aspect step that the aspect state data shows. The terminal device 12 receives determination reference data generated for each aspect step from a server device 13 and stores the same. The terminal device 12 determines whether or not motion that the locus data of the mobile body shows is normal on the basis of the determination reference data according to the aspect step at the time when the mobile body has passed the intersection 5.SELECTED DRAWING: Figure 1

    【課題】交差点を通過する移動体の動きを監視するために要する労力を軽減する。【解決手段】端末装置12は交差点5に設置された撮像装置11から動画像データを受信するとともに、信号制御装置8から信号機6および信号機7の現示状態を示す現示状態データを受信し、現示状態データが示す現示階梯のステップ毎に動画像データが示す移動体の動きを示す軌跡データを生成する。端末装置12は現示階梯のステップ毎に生成された判定基準データをサーバ装置13から受信し記憶している。端末装置12は移動体が交差点5を通過したときの現示階梯のステップに応じた判定基準データに基づき、当該移動体の軌跡データが示す動きが正常であるか否かを判定する。【選択図】図1
