PROBLEM TO BE SOLVED: To collect a required amount of travel data while suppressing useless load and cost at the side of a travel data collection center.SOLUTION: A travel data collection system includes: an on-vehicle terminal 2 which is mounted on a vehicle and comprises a travel data acquisition unit configured to acquire travel data and a transmission unit configured to transmit the travel data that are acquired by the travel data acquisition unit; and a travel data collection center 3 comprising a receiving unit 312 configured to collect travel data that are transmitted from on-vehicle terminals 2 on multiple vehicles. The travel data collection center comprises: a target road table generation unit 36 which determines, for each vehicle, a link for collecting travel data from a vehicle according to travel frequencies of multiple vehicles for each road section; and a transmission unit 311 which transmits, to the on-vehicle terminal 2 of each of vehicles, a target road table for acquiring travel data in the on-vehicle terminal 2 of each of vehicles over the link that is determined for each vehicle by the target road table generation unit 36.SELECTED DRAWING: Figure 3
【課題】走行データ収集センタ側での無駄な負荷及びコストを抑えて必要な量の走行データを収集することを可能にする。【解決手段】車両に搭載され、走行データを取得する走行データ取得部と、走行データ取得部で取得した走行データを送信する送信部とを備える車載端末2と、複数の車両の車載端末2から送信される走行データを収集する受信部312を備える走行データ収集センタ3とを含み、複数の車両の道路区間別の走行頻度に応じて、車両から走行データを収集するリンクを、車両別に決定する対象道路テーブル生成部36と、対象道路テーブル生成部36で車両別に決定したリンクにおいてそれぞれの車両の車載端末2で走行データを取得させるための対象道路テーブルを、それぞれの車両の車載端末2へ送信する送信部311とを備える。【選択図】図3
