Abstract: A method comprising: collecting a plurality of probe data from a plurality of probe points by a probing device, said probe data comprising at least positional information, a speed vector and a direction of travel of the probing device and a timestamp of recording the probe data at a probe point; and estimating a trajectory of the probing device between two consecutive probe points as a cubic Hermite spline having the positions of said two consecutive probe points as control points and the speed vectors of said two consecutive probe points as control vectors.

Abstract: Probe data including points with geographic locations and heading angles are identified for a geographic area. A translation is performed on the points in the probe data in a predetermined direction orthogonal to the corresponding heading. The translated points are aggregated according to a location grid. The aggregated points are analyzed from the location grid according to the heading. A potential location for a center of a roundabout road formation is determined based on the analysis.

Abstract: An approach is provided for providing routing calculations and route guidance based on geographic positioning and/or other sensor data from one or more mobile devices independent of map data. A routing platform processes and/or facilitates a processing of one or more probe data samples associated with at least one mobile device to determine one or more device tracks. The routing platform processes and/or facilitates a processing of the one or more device tracks to determine at least one tessellation, wherein the at least one tessellation is a subdivision of a plane or sphere into one or more tiles and a plurality of segments. The routing platform further determines one or more relationships between one or more of the plurality of segments based, at least in part, on a mapping of the one or more device tracks against the at least one tessellation.

Abstract: A method is provided that includes: receiving a plurality of estimated position points, each estimated position point including a timestamp, where each estimated position point is an estimate of a position of a vehicle at a time respective timestamp; receiving on or more path events, where each of the one or more path events includes a timestamp and data from at least one sensor of the vehicle; generating a path from the plurality of estimated position points, where the estimated position points are arranged in order of ascending time represented by the respective timestamp; and interpolating between two of the estimated position points to determine a location corresponding to one of the one or more path events, where the timestamp of the one of the one or more path event corresponds to a time that is between the times represented by the timestamps of the two estimated position points.
