Abstract: An approach is provided for detecting stay points from probe data. The approach, for example, involves segmenting a probe trajectory into a first trajectory segment type (e.g., on-road), a second trajectory segment type (e.g., off-road), an unknown trajectory segment type, or a combination thereof. The approach also involves merging the unknown trajectory segment into either the first trajectory segment type or the second trajectory segment type based on a co-occurrence with the unknown trajectory segment. The approach further involves segmenting the first trajectory segment type into first sub-segments and the second trajectory segment type second sub-segments based on a minimum enclosing ball or any other bounding volume with a radius less than or equal to the distance threshold. The approach further involves processing each first sub-segment and each second sub-segment to determine stay points.

The probe data are collected from sensors of a plurality of devices traveling in the bounded geographic area, and includes probe points indicating a position, a heading, a speed, a time, or a combination thereof. The approach also involves constructing a plurality of trajectories from the probe points to represent respective movement paths of said each of the plurality of devices. The approach further involves computing similarities among a plurality of curves represented by the plurality of trajectories. The approach further involves clustering the plurality of trajectories into trajectory bundles based on the similarities with each bundle representing a possible maneuver within the bounded geographic area. The approach further involves generating a map of the bounded geographic area based on the trajectory bundles.

Abstract: Apparatus and methods are described for identification of a geographic location for sign placement. Probe data is received for a geographic area, and the probe data is collected by one or more sensors. Trips including destinations within the geographic area are matched with road segments from a geographic database. At least one potential sign placement road segment is compared to road segments of the trip. One or more destinations are selected from the trips based on the comparison of the at least one sign placement road segment to the trip road segments.
