To provide congestion information effectively.SOLUTION: A congestion information provision device 1 comprises a speed-related information acquisition unit 10, a determination unit 20, a switching unit 30, a transmission unit 40, and a Geohash unit 50. The speed-related information acquisition unit 10 acquires speed-related information that pertains to the speed of a moving vehicle in a target section from multiple types of communication terminal moving in the targe section together with the moving vehicle and differing in an information upload frequency. The determination unit 20 determines whether or not there is occurrence of a congestion in the target section by using the speed-related information and a prescribed determination logic. The switching unit 30 switches the determination logic using the number and the type of multiple types of communication terminals present in the target section or in a prescribed region including at least the target section.SELECTED DRAWING: Figure 1

    【課題】 渋滞情報を効果的に提供することである。【解決手段】渋滞情報提供装置1は、速度関連情報取得部10と、判断部20と、切替部30と、送信部40と、ジオハッシュ部50とを備えている。速度関連情報取得部10は、対象区間を移動体とともに移動し、情報アップロードの頻度が異なる複数種類の通信端末から、対象区間における移動体の速度に関する速度関連情報を取得する。判断部20は、速度関連情報及び所定の判断ロジックを用いて、対象区間において渋滞が発生しているか否かを判断する。切替部30は、対象区間又は対象区間の少なくとも一部を含む所定の領域に存在する複数種類の通信端末の台数及び種類を用いて判断ロジックを切り換える。【選択図】図1
