To provide a technology capable of acquiring traffic information for accurately analyzing a factor that causes a traffic event such as a traffic jam or an accident.SOLUTION: A vehicle detection part 21 detects a vehicle 100 which is being traveled along a track. Regarding the vehicle 100 that is detected by the vehicle detection part 21, a vehicle tracking part 22 makes a detection time of the vehicle 100 correspondent to a detection position and generates detection data. An attribute information adding part 23 associates a gradient of a road surface of the track at the detection position of the vehicle 100 with the detection data as one of attribute information.SELECTED DRAWING: Figure 1
【課題】渋滞や事故等の交通事象が発生する要因の解析が精度よく行える交通情報の取得が行える技術を提供する。【解決手段】車両検知部21は、走行路を走行している車両100を検知する。車両追跡部22は、車両検知部21が検知した車両100について、当該車両100の検知時刻と検知位置とを対応付け検知データを生成する。属性情報付加部23は、車両100の検知位置における走行路の路面の勾配を属性情報の1つとして検知データに紐づける。【選択図】図1
