To provide an information processing server capable of updating a behavior discrimination model at an appropriate timing according to a situation of a set area.SOLUTION: An information processing server for obtaining target vehicle data from a plurality of target vehicles, comprises: an unstable behavior position recognition unit that recognizes an unstable behavior position of the target vehicle based on the target vehicle data; a model generation unit that generates a behavior discrimination model from the target vehicle data of the target vehicle at the unstable behavior position for each of a plurality of set areas set on a map; a statistical value calculation unit that calculates either a vehicle traffic statistical value in the set area or an unstable behavior statistical value in the set area; a model updating necessity determination unit that determines whether updating of the behavior discrimination model is necessary based on a change in the vehicle traffic statistical value or the unstable behavior statistical value since the behavior discrimination model was generated in the set area; and a model updating unit that updates the behavior discrimination model in the set area when it is determined that the behavior discrimination model is required to be updated.SELECTED DRAWING: Figure 10
【課題】設定エリアの状況に応じた適切なタイミングで挙動判別モデルの更新を行うことができる情報処理サーバを提供する。【解決手段】複数台の対象車両から対象車両データを得る情報処理サーバであって、対象車両データに基づいて、対象車両の不安定挙動位置を認識する不安定挙動位置認識部と、地図上に複数設定された設定エリアごとに、不安定挙動位置における対象車両の対象車両データから挙動判別モデルを生成するモデル生成部と、設定エリアにおける車両通行統計値又は設定エリアにおける不安定挙動統計値を算出する統計値算出部と、設定エリアで挙動判別モデルが生成されたときからの車両通行統計値の又は不安定挙動統計値の変化に基づいて、挙動判別モデルの更新が必要であるか否かを判定するモデル更新要否判定部と、挙動判別モデルの更新が必要であると判定された場合に設定エリアの挙動判別モデルの更新を行うモデル更新部と、を備える。【選択図】図10
