1. An information processing system, comprising:

  • a history obtainer that obtains a personal driving environment history of each of a plurality of drivers, each of personal driving environment histories indicating one or more behaviors, of a vehicle, selected by a driver, and a driving environment associated with each of the one or more behaviors, the driving environment being a driving environment of the vehicle at a point in time of a selection of a behavior it is associated with;

    a modeler that models, from a driving environment history including the personal driving environment histories of the plurality of drivers, the personal driving environment history of at least one of the plurality of drivers, to build a driver model indicating a relationship between the driving environment and a selected behavior for the vehicle of the at least one of the plurality of drivers;

    an environment obtainer that obtains a driving environment of a vehicle of a target driver that is a target for estimation;

    a behavior estimation unit configured to, in the driver model built, estimate an estimated behavior of the target driver, the estimated behavior being associated with the driving environment obtained by the environment obtainer; and

    a display unit configured to display a behavior candidatewherein each of the personal driving environment histories of the plurality of driversindicates, for each of the one or more behaviors, of the vehicle, selected by the driver, a first parameter set which is a parameter set including each value of at least one environment parameter, as the driving environment of the vehicle at the point in time of selection of the behavior, and a second parameter set which is a parameter set including each value of at least one environment parameter, as the driving environment at a time a corresponding behavior was displayed as the behavior candidate,the modelermodels the value of each environment parameter included in the first parameter set and the value of each environment parameter included in the second parameter set indicated in the personal driving environment history of the at least one of the plurality of drivers, to build the driver model indicating a relationship between the first parameter set, the second parameter set, and the selected behavior for the vehicle of the at least one of the plurality of drivers,the environment obtainerobtains the driving environment of the vehicle of the target driver that is the target for estimation as a parameter set, andthe behavior estimation unitis configured to, in the driver model built, estimate the estimated behavior of the target driver, the estimated behavior being associated with the first parameter set or the second parameter set that is similar to the parameter set obtained by the environment obtainer.
