PROBLEM TO BE SOLVED: To provide a bad road determination system which determines that a road surface condition is recovered.SOLUTION: A bad road determination system 10 comprises a bad road section acquisition unit 21a for acquiring a bad road section which is a road section determined to have a bad road surface condition, and a determination unit 21b for, in the case where an absolute value of acceleration of a vehicle in the bad road section is a threshold or greater, determining that the road surface condition of the bad road section has been recovered. The system further comprises a running information reception unit 22 for receiving running information which indicates acceleration in the bad road section from at least a plurality of vehicles and an instruction information transmission unit 21e for transmitting, to the plurality of vehicles, instruction information for executing different drive support between the case where it is determined that the road surface condition in the bad road section has been recovered and the case where it is not determined that the road surface condition in the bad road section has been recovered.SELECTED DRAWING: Figure 1 |
