A computer-implemented method for acquiring a velocity of a vehicle, detecting whether the velocity is in a fluctuating state, and determining that the vehicle is in traffic congestion, in response to a parameter of the velocity being less than or equal to a predetermined threshold value and the velocity being detected to be in the fluctuating state. The computer-implemented method may further be capable of acquiring a position of the vehicle and identifying a position of a tail end of the traffic congestion, based on the position of the vehicle determined to be in the traffic congestion. In exemplary embodiments, if a ratio of vehicles capable of acquiring information is low, then the accuracy of an estimation of traffic congestion also becomes low.
