PROBE DATA ANALYSIS SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a probe data analysis system for accurately extracting a trip end in performing automatic analysis by using probe data having positioning point data of a mobile terminal collected without using a WEB diary as elements. SOLUTION: The system includes: a section identification means for identifying a section between consecutive two pieces of positioning point data as one unit section among a probe data set having the positioning point data of a mobile terminal positioned at fixed time intervals as elements; a speed calculation means for obtaining the speed of the mobile terminal in the unit section; a speed evaluation means for evaluating that the speed of the mobile terminal meets which of speed standards including evaluation corresponding to walk; a short trip extraction means for determining a range in which unit sections of the same evaluation are continued; and a staying type short trip identification means for determining a positioning point concentrated area from positioning point data composing a continuous section of evaluation corresponding to walk; and a trip end extraction means for extracting positioning point data to be a start point and an end point in the concentrated area.
