Abstract: An evaluating apparatus is provided with: a first acquirer configured to obtain a feature value indicating driving behavior of a driver; a classifier configured to classify a plurality of feature values obtained from a plurality of drivers, into a plurality of groups; a second acquirer configured to obtain the feature value that is representative in each of the plurality of groups, as a representative feature value; a ranking device configured to give a rank corresponding to a driving carefulness degree, to each of the plurality of groups, on the basis of the representative feature value; and a determinator configured to determine a driver type corresponding to the driving carefulness degree of the driver, on the basis of a rank of a group into which the feature value of the driver is classified.

Abstract: An evaluating apparatus is configured to evaluate a risk that exists in surroundings of a road on which a vehicle travels. The evaluating apparatus is provided with: a first determinator configured to determine a first risk value indicating an extent of a risk in one section of the road, on the basis of a feature value indicating driving behavior of a driver of the vehicle; a second determinator configured to determine a second risk value indicating an extent of a risk in the one section, on the basis of surrounding information about the surroundings of the road; and an acquirer configured to obtain reliability of the second risk value, by evaluating the second risk value by using the first risk value.

Abstract: An evaluating apparatus is provided with: a first determinator configured to determine a first risk value indicating whether or not there is a risk in one section of the road and an extent of the existing risk; a second determinator configured to determine a second risk value indicating whether or not there is a risk in the one section and an extent of the existing risk; and an outputting device configured such that if it is determined on said first determinator that there is a risk, said outputting device outputs the first risk value as a definite risk value indicating the risk in the one section, and such that if it is determined on said first determinator that there is no risk and if it is determined on said second determinator that there is a risk, said outputting device outputs the second risk value as the definite risk value.
