  "textContent": "The invention provides a road surface condition determining system with improved accuracy. In the system, a plurality of vehicles Ware used, each equipped with on-board sensors () for acquiring vehicular information, which is information on the behavior of the vehicle during travel, a feature value calculating means () for calculating a plurality of feature values to be used in estimating the condition of the road surface on which the vehicle is traveling from the vehicular information acquired by the on-board sensors (), and a transmitter for transmitting the feature values to the outside of the vehicle. A server () has a data storage means () for accumulating the plurality of feature values from the plurality of vehicles. A road surface condition determining unit () determines a road surface condition using the accumulated feature values. And the system determines the road surface condition at the location within a predetermined range within a predetermined space of time.",
