The present invention relates to a computer system for calculating accurate estimations of traffic velocity in a road network. The system comprises a plurality of devices, each device operable to deliver speed measurement data corresponding to the speed of a traffic flow in the road network. The system further comprises at least one computational unit, wherein each of the plurality of devices sends speed measurement data to the computational unit. The computational unit is operable to calculate accurate estimations of traffic velocity in the road network for specific regions by identifying regions with varying sizes and moving boundaries under the condition that within each region, a corresponding traffic phase p is constant, wherein each traffic phase is one of a free-flow phase, a synchronized phase or a wide moving jam phase; and calculating accurate estimations of traffic velocity in said regions based on the corresponding traffic phases.
