Abstract: A method, apparatus and computer program product are provided in order to provide at least approximate real-time intelligent gap placement within mobility data using junctions inferred by features of the mobility data. In this regard, a data chunk associated with a sequence of location probe data points representative of travel of a vehicle along a portion of a road network is received. Additionally, junction behavior in the data chunk is identified based on one or more features for the sequence of location probe data points. Based on a status of a previous data chunk and a junction point that corresponds to a location probe data point immediately after a last probe data point in the junction, a gap placement or a sub-trajectory is applied in the sequence of location probe data points to generate at least a first subsequence and second subsequence of the location probe data points.

Abstract: An approach is disclosed for a data-driven evaluation of heuristics for trajectory cropping. The approach involves, e.g., determining a cropping heuristic, wherein the cropping heuristic comprises an algorithm for cropping a probe trajectory collected from one or more sensors of a mobile device to anonymize the probe trajectory data. The approach also involves processing the probe trajectory using the cropping heuristic to generate a cropped probe trajectory. The approach further involves extracting one or more heuristic-based features of the cropped probe trajectory data. The approach also involves extracting one or more privacy-based features from a privacy preference, wherein the one or more privacy-based features represent a target level of cropping to meet the privacy preference. The approach further involves computing a score based on a distance between the one or more heuristic-based features and the one or more privacy-based features. The approach further involves providing the score as an output.
