PROBLEM TO BE SOLVED: To restrict unnecessary road-related data from being transmitted from a vehicle to a server.SOLUTION: A transmission necessity determination device 101 for determining whether road-related data acquired by an on-vehicle system is to be transmitted from a vehicle to a server 102 includes: a stability degree acquisition section 22 for acquiring a stability degree of the on-vehicle system for each position from the on-vehicle system; and a transmission necessity determination section 23 for determining whether road-related data is to be transmitted from the vehicle to the server on the basis of at least one of a collection degree of road-related data for each position and freshness of road-related data for each position and also a stability degree of the on-vehicle system for each position. The transmission necessity determination section 23 determines that road-related data of a position where a collection degree is equal to or more than a collection degree threshold or freshness is equal to or more than a freshness threshold is not to be transmitted from the vehicle to the server 102, and also determines that road-related data of a position where a stability degree of the on-vehicle system is lower than a stability degree threshold is not to be transmitted from the vehicle to the server 102.SELECTED DRAWING: Figure 4

    【課題】不要な道路関連データを車両からサーバに送信することを抑制することができる。【解決手段】車載システムが取得した道路関連データを車両からサーバ102に送信するか否かを判定する送信要否判定装置101であって、車載システムから位置毎の車載システムの安定度を取得する安定度取得部22と、位置毎の道路関連データの収集度合及び位置毎の道路関連データの鮮度のうち少なくとも一方と位置毎の車載システムの安定度とに基づいて道路関連データを車両からサーバに送信するか否かを判定する送信要否判定部23と、を備え、送信要否判定部23は、収集度合が収集度合閾値以上又は鮮度が鮮度閾値以上の位置の道路関連データを車両からサーバ102に送信しないと判定すると共に、車載システムの安定度が安定度閾値未満の位置の道路関連データを車両からサーバ102に送信しないと判定する。【選択図】図4
