Claim 8:
9. A method for generating vehicle data-based boarding and alighting point information, the method comprising:
a time series data processing operation of receiving a plurality of time series data including first speed data of a vehicle from a plurality of sensors of the vehicle, and resampling the time series data based on a preset first time;
a Global Positioning System (GPS) data processing operation of resampling GPS data, which are related to a GPS of the vehicle and including second speed data of the vehicle based on a preset second time;
a location data deriving operation of integrating the time series data and the GPS data based on the first speed data, the second speed data, and Dynamic Time Warping (DTW) algorithm, and obtaining location data of the vehicle from the integrated data;
a location integrating operation of integrating location information of a vehicle boarding point and a vehicle alighting point received from a public institution; and
an identifier generating operation of generating a boarding point identifier and an alighting point identifier related to a location of the boarding point and the alighting point, respectively, in the location data of the vehicle based on the location information of the vehicle boarding point and the vehicle alighting point,
wherein the location data deriving operation includes:
calculating Euclidean distances of the first speed data and the second speed data for each time axis;
selecting minimum distance ordered pairs with minimum Euclidean distances; and
integrating the time series data and the GPS data based on the ordered pairs.
