Abstract
In one implementation, sets of probe data are collected by probe vehicles. The probe data describes the driving characteristics of the probe vehicles. The sets of probe data are sent to a server or a mobile device for analysis. A polycurve, including a piecewise function of map data, is modified based on the probe data. The polycurve may be a spline curve for an advanced driver assistance system. The modified polycurve may be used in the advanced driver assistance system for a vehicle traveling along the same path previously traversed by the probe vehicles. Based on the polycurve modified by the probe data, a driver assistance feature is provided to the vehicle.

7. An apparatus comprising:
-
at least one processor; and at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following; receiving data collected by sensors of multiple vehicles indicative of a position of a vehicle; determining a driving behavior of the vehicle; comparing the driving behavior of the vehicle to a threshold of typical driver behavior dimension of a data model wherein the threshold of typical driver behavior includes a first position where drivers begin braking and a second position where drivers stop braking; and generating a warning when the driving behavior indicates that the typical driver behavior dimension has been exceeded. - View Dependent Claims (8, 9, 10, 11, 12)
