A driving action classifying apparatus comprising: a driving-action-symbol acquiring unit configured to acquire position information on a vehicle; acquire, from the vehicle including a plurality of sensors, sensor data on the vehicle at the time when the sensor data is generated, wherein the sensor data comprises speed, acceleration, a steering angle, and a yaw rate; generate an action element symbol that is a symbol representing a behavior of the vehicle in a first predetermined period of time by clustering the acquired sensor information; and generate driving action symbols from action element symbols for a second predetermined period of time that is longer as the first predetermined period of time by generating a histogram representing a distribution of the action element symbols for the second predetermined period of time and clustering the histogram; and a tendency symbolizing unit configured to collect the driving action symbols corresponding to a same place or where characteristics of a road are similar acquired from a plurality of vehicles and generate driving tendency symbols, which are data obtained by converting into a symbol a frequency distribution of the driving action symbols, the driving action classifying apparatus further comprising a point specifying unit configured to specify, on the basis of a change of the driving tendency symbols and position information corresponding to the driving tendency symbols, a place where a peculiar driving action has occurred, and the driving action classifying apparatus further comprising an information presenting unit configured to output the driving tendency symbols to a screen and to notify a user of the change in the driving tendency symbols at the place where the peculiar action has occurred. a driving-action-symbol acquiring unit configured to acquire position information on a vehicle;
