To identify the motion of various vehicles on a road.SOLUTION: Provided is a travel history analyzing system comprising a travel history acquisition unit for acquiring a travel history indicating a vehicle speed at each point from a plurality of vehicles and a road type acquisition unit for statistically processing the vehicle speeds of the plurality of vehicles on the basis of the travel history and acquiring the type of approach road to an intersection. The road type acquisition unit acquires the approach road as a road where a temporary stop point is included, when the percentage of vehicles the vehicle speeds of which are smaller than or equal to a first threshold in the same section of the approach road is equal to or larger than a prescribed value, acquires the approach road that is not a road where the temporary stop point is included and the percentage of vehicles the vehicle speeds of which are smaller than or equal to a second threshold larger than the first threshold is a prescribed section before the intersection is greater than or equal to a prescribed value, as a road where a deceleration point is included, and acquires roads that are not classified into these, as a road where deceleration is not required.SELECTED DRAWING: Figure 1
【課題】道路上での種々の車両の動作を特定することを目的とする。【解決手段】地点毎の車速を示す走行履歴を複数の車両から取得する走行履歴取得部と、前記走行履歴に基づいて複数の前記車両の前記車速を統計し、交差点への進入道路の種別を取得する道路種別取得部と、を備え、前記道路種別取得部は、前記進入道路上の同一区間内において前記車速が第1閾値以下となった前記車両の割合が既定値以上である場合に、当該進入道路を、一時停止地点が含まれる道路として取得し、前記一時停止地点が含まれる道路ではなく、かつ、前記交差点手前の既定区間における前記車速が前記第1閾値より大きい第2閾値以下となった前記車両の割合が既定値以上である前記進入道路を、減速地点が含まれる道路として取得し、これらに分類されない道路を、減速されない道路として取得する、走行履歴解析システムが構成される。【選択図】図1
