1. A personalized safe driving assistance method comprising: collecting, for each of a plurality of collection target vehicles, information on a first risk determination factor to an N-th risk determination factor corresponding to the collection target vehicle during a predetermined measurement period, by a personalized safe driving assistance system (here, N is an integer greater than or equal to 3);
modeling a standard safety area in an N-dimensional space expressed in an N-axis coordinate system orthogonal to each other based on the information collected from the plurality of collection target vehicles during the measurement period, wherein each coordinate axis of the N-dimensional space corresponds to any one among the first risk determination factor to the N-th risk determination factor, by the personalized safe driving assistance system;
determining a defensive driving level of a warning target vehicle driver based on past driving data of the warning target vehicle driver driving a predetermined warning target vehicle, by the personalized safe driving assistance system; specifying a personalized safety area corresponding to the warning target vehicle driver based on the defensive driving level of the warning target vehicle driver, by the personalized safe driving assistance system, wherein the personalized safety area is an area obtained by correcting the standard safety area based on the defensive driving level of the warning target vehicle driver;
periodically acquiring information on the first risk determination factor to the N-th risk determination factor corresponding to the warning target vehicle while the warning target vehicle is running, by the personalized safe driving assistance system;
determining whether there is a risk based on the acquired information on the first risk determination factor to the N-th risk determination factor corresponding to the warning target vehicle and the personalized safety area corresponding to the warning target vehicle driver, by the personalized safe driving assistance system; and
outputting a warning to the driver of the warning target vehicle based on a result of determining whether there is the risk.
