1. A method comprising:

  • receiving, by a processor, a plurality of sets of probe data collected by probe vehicles;

    determining a threshold level of speed or acceleration based on the plurality of sets of probe data, wherein the threshold level is a function of position;

    modifying a polycurve based on the plurality of sets of probe data, wherein the polycurve is a piecewise function of map data; and

    generating data for a driver assistance feature based on the polycurve modified based on the plurality of sets of probe data;

    wherein the driver assistance feature generates a warning if a current level of speed or acceleration exceeds the threshold level of speed or acceleration.
