  "textContent": "The invention provides a road surface condition determining system with improved accuracy. In the system, a plurality of vehicles W i are used, each equipped with on-board sensors (11, 12) for acquiring vehicular information, which is information on the behavior of the vehicle during travel, a feature value calculating means (13) 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 (11, 12), and a transmitter 16 for transmitting the feature values to the outside of the vehicle. A server (20) has a data storage means (22) for accumulating the plurality of feature values from the plurality of vehicles. A road surface condition determining unit (30) 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.",
