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. 9465396_1 (GHMatters) P106843.AU 0,It ZC/) F--J _____< ___ LUJ UJ F-$: F LU-L a UL U L U)0 -J % 0i _ _ _ _4
