PROBLEM TO BE SOLVED: To provide a road surface state discrimination system that improves discrimination accuracy of a road surface state.SOLUTION: A road surface state discrimination system comprises: on-vehicle sensors 11 and 12 that acquire vehicle information being information on a behavior of a vehicle upon travelling; a characteristic-amount calculation means 13 that calculates a plurality of amounts of characteristic for presuming a state of a road surface to be travelled by the vehicle from the vehicle information acquired by the on-vehicle sensors 11 and 12; a plurality of vehicles Wthat includes a transmitter 16 transmitting the amount of characteristic to an exterior of the vehicle; a server 20 that has data storage means 22 accumulating the plurality of amounts of characteristic of the plurality of vehicles; and a road surface state discrimination device 30 that discriminates the road surface state using the accumulated amounts of characteristic. The road surface state discrimination system discriminates the road surface state in a prescribed time and prescribed range.SELECTED DRAWING: Figure 1
