PROBLEM TO BE SOLVED: To collect more data while controlling the tightness of communication lines.SOLUTION: A roadside communication device having a relay function of data comprises: a communication unit that receives mobile body data generated by a mobile body; a determination unit that determines whether thinning-out processing of the data amount of the mobile body data received by the communication unit should be performed or not on the basis of a prescribed determination condition; and a relay unit that relays the mobile body data while performing the thinning-out processing if a determination result at the determination unit is affirmative, and relays the mobile body data without performing the thinning-out processing if the determination result at the determination unit is negative.SELECTED DRAWING: Figure 4
【課題】通信回線の逼迫を抑制しつつ、より多くのデータを収集する。【解決手段】データの中継機能を有する路側通信装置であって、移動体が生成元の移動体データを受信する通信部と、所定の判定条件に基づいて、前記通信部が受信した前記移動体データのデータ量の間引き処理を行うか否かを判定する判定部と、前記判定部の判定結果が肯定的である場合は前記間引き処理を伴う前記移動体データの中継を行い、前記判定部の判定結果が否定的である場合は前記間引き処理を伴わずに前記移動体データの中継を行う中継部と、を備える路側通信装置。【選択図】図4
