According to one embodiment, a road traffic condition estimation system includes a storage, an inter-vehicle distance estimator, a vehicle density estimator, and a traffic flow rate estimator. The storage stores a speed and inter-vehicle distance table representing a relationship between vehicle speeds and inter-vehicle distances. The inter-vehicle distance estimator acquires a representative value of speeds of vehicles traveling on a given section of a road, and estimates a representative value of inter-vehicle distances on the section on the basis of the representative value of the speeds and the speed and inter-vehicle distance table. The vehicle density estimator estimates a vehicle density on the section on the basis of the estimated representative value of the inter-vehicle distances and a length of the section. The traffic flow rate estimator estimates a traffic flow rate on the section on the basis of the representative value of the speeds and the estimated vehicle density.
