To provide a data collection device for map generation that can predict the number of data for map generation to be collected within a predetermined period of time in the future for road sections where the number of collected data for map generation has not reached a target collection number among a plurality of road sections in an area subject to map generation or updating.SOLUTION: A data collection device for map generation includes: a counting unit 42 that counts, for each of a plurality of road sections, a number of data for map generation received from at least any one of vehicles 2 in a first period of time; an identifying unit 43 that identifies a road section among the plurality of road sections for which the number of map generation data received during the first period has not reached a target collection number for the road section; and a prediction unit 44 that predicts the number of data for map generation to be received in a future second period later than the first period based on a history of traffic volume for each environmental condition or a history of the number of received data for map generation for that road section in the past for the identified road section.SELECTED DRAWING: Figure 5
【課題】地図生成または更新の対象となる領域内の複数の道路区間のうち、収集された地図生成用データの数が目標収集数に達していない道路区間について、将来の所定期間内に収集される地図生成用データの数を予測できる地図生成用データ収集装置を提供する。【解決手段】地図生成用データ収集装置は、第1の期間において、少なくとも一つの車両2の何れかから受信した地図生成用データの数を、複数の道路区間のそれぞれについて計数する計数部42と、複数の道路区間のうち、第1の期間において受信した地図生成用データの数がその道路区間についての目標収集数に達していない道路区間を特定する特定部43と、特定された道路区間について、環境条件ごとの交通量の履歴またはその道路区間についての過去の地図生成用データの受信数の履歴に基づいて、第1の期間よりも後の将来の第2の期間に受信する地図生成用データの数を予測する予測部44とを有する。【選択図】図5
