PROBLEM TO BE SOLVED: To provide a data concentration part extraction method acquired from probe data capable of easily and reliably extracting a data concentration part where a specific act is performed such as a rapid deceleration part, from multiple pieces of probe data.SOLUTION: The data concentration part extraction method includes: a step of collecting latitude and longitude data that are acquired from the multiple pieces of probe data and where specific acts are performed; a concentration level scoring step of calculating a distance of one piece of the data to other pieces of data contained in a prescribed area, with the one piece of data used as a center, weighting it more as the distance closing nearer to the one piece of data, and calculating a total value as a concentration level score of the one piece of data; and a peak extraction step of extracting the one piece of data that is a peak of the concentration level score on the basis of increase/decrease in the concentration level score between adjacent pieces of data. |
