1. A computer system for measuring traffic speed on road segments of a road network in a geographic area, comprising:

  • computer storage comprising;

    sample data associating speed of sampled vehicles on road segments to points of time in a plurality of time slots, the sample data being derived from location data received from sensors that provide location data over time of the sampled vehicles;

    correlation data defining correlations among road segments and correlations among time slots;

    one or more processing units programmed to access the computer storage to process the sample data using the correlation data to provide an output describing, for each road segment in the road network, at least an average vehicle speed for each road segment in the road network for at least the current time slot.
