1. A method for providing a traffic pattern for a road segment of navigation map data on the basis of time series traffic data Y(t), the method comprising:

  • determining reference time series ρ

    (t) for the road segment used to approximate the time series traffic data Y(t);

    determining a weighted combination of the reference time series ρ

    (t) by determining weighted coefficients, α

    , that determine how much a predetermined reference time series contributes to the combination of the reference time series for approximating the time series traffic data Y(t);

    approximating the time series traffic data Y(t) by the weighted combination of the reference time series ρ

    (t); and

    linking the determined weighting coefficients α

    to the road segment of the navigation map data.
