Summary:PROBLEM TO BE SOLVED: To provide a system, method, and program, that make it possible to perceive a road surface situation accurately and in a pinpoint manner.SOLUTION: A portable device 100 includes a walking data collection unit 110 that collects sensor data on each sensor device, and a positioning unit 120 that collects positioning information on the portable device 100, the collected data and information with time stamps being recorded in a walking data storage unit 130 and positioning data storage unit 180 of an information processing device 90, respectively. A walking step recognition unit 140 recognizes a walking step showing individual foot motion in a person walking, on the basis of recorded data in the storage unit 130. A walking data segmentation unit 150 segments recognition information to identify walking data associated with a walking step. A step analysis unit 160 classifies the walking data in association with a road surface situation to record the classified data in a walking data analysis result storage unit 170. A by-position road surface situation understanding unit 190 perceives a road surface situation on the basis of both storage units 170, 180.SELECTED DRAWING: Figure 1 【課題】高精度かつピンポイントに路面状況を把握できるシステム、方法、プログラムを提供する。【解決手段】携帯デバイス１００の歩行データ収集部１１０は各センサデバイスのセンサデータを収集し、測位部１２０は携帯デバイス１００の測位情報を収集し、収集された各情報はそれぞれタイムスタンプと併せて情報処理装置９０の歩行データ蓄積部１３０，測位データ蓄積部１８０に記録される。歩行ステップ認識部１４０は、蓄積部１３０の記録データに基づき人が歩行する際の個々の足の運びを示す歩行ステップを認識する。歩行データセグメント化部１５０は、前記認識情報をセグメント化して歩行ステップと対応付けられる歩行データを特定する。ステップ分析部１６０は、前記歩行データを路面状況に対応付ける形で分類し、歩行データ分析結果蓄積部１７０に記録する。位置別路面状況理解部１９０は、前記両蓄積部１７０，１８０に基づき路面状況を把握する。【選択図】図１
