Abstract: A method, apparatus and computer program product are provided to determine a measure of probe quality, such as a level of accuracy with which the location of a probe point is defined. In the context of a method and for a plurality of probe points, a distance is determined between a respective probe point and a line representative of a link. For the plurality of probe points, the method also includes determining a difference between a bearing of the respective probe point and a bearing of the link. The method further includes determining the measure of probe quality based upon a product of a representation of the distance between the plurality of probe points and the line representative of the link and a representation of the difference between the bearing of the plurality of probe points and the bearing of the link.

Abstract: System and methods are provided for generating lane aware clusters for vehicle to vehicle communications. A vehicle uses lane level map matching to obtain a current travelling lane. Vehicles that are within a proximity radius exchange data such as location, lane, speed, direction. Sub clusters are creating with vehicles driving on the same lane based on proximity distance. The sub clusters are merged into one cluster based on sub cluster similarity in terms of spatial proximity, average speed, and direction.

Abstract: An approach is provided for speed aggregation of probe data for high-occupancy-vehicle (HOV) or other road lanes. The approach involves, for example, determining a line that is parallel to a road segment and divides the road segment along a longitudinal axis. The approach also involves determining a spatial distribution of probe data collected from the road segment with respect to the line. The approach further involves clustering the probe data into a first cluster and a second cluster based on speed. The approach further involves assigning the first cluster to a first lane of the road segment, the second cluster to a second lane of the road segment, or a combination thereof based on the spatial distribution to output a bi-modality event (e.g., an HOV traffic event).

Abstract: An approach is provided for mining pedestrian probe data from mix-mode probe data. The approach involves, for example, receiving a probe trajectory including a vehicle mode of travel, a pedestrian mode of travel, or a combination thereof. The approach also involves processing the probe trajectory to determine at least one speed value and at least one sinuosity value. The approach further involves determining a pedestrian probe detection metric based on the at least one speed value and the at least one sinuosity value. The approach further involves ranking the probe trajectory among a plurality of probe trajectories based on the pedestrian probe detection metric and/or classifying the probe trajectory as either a vehicle probe trajectory or a pedestrian probe trajectory based on the pedestrian probe detection metric.

Abstract: System and methods are provided for a supervised point map matcher. The supervised point map matcher learns parameters from historical data that provide insight into the optimal probabilistic metrics that inform the bias of probes heading and distance for segments on the roadway. Probability weights for segments are generated. A more accurate path based map matching algorithm is used to identify direction and heading errors in the historical probe data. Values for the probability weights are calculated using kernel density estimation and a gaussian probability density function. The probability weights are used to improve the real time performance of the point map matcher. A confidence value is calculated as a function of the probability weights and provided with the map matched results.

Abstract: A method, apparatus, and computer program product are provided for dynamically detecting dangerous merging situations. The method includes obtaining speed information for one or more road segments. The speed information includes lane-level traffic speed information. The method also includes determining a source speed of a source lane and a target speed of a target lane based on the speed information. The method further includes determining that a merging instance from the source lane into the target lane would be a dangerous merging situation based on a comparison of the source speed and the target speed. The method still further includes providing a signal based on the determination of a dangerous merging situation. A corresponding apparatus and computer program product are also provided.

Abstract: One or more lane level dynamic profiles are received. Each lane level dynamic profile comprises at least one dynamic parameter corresponding to a lane of a traversable network. A lane level network graph is received for at least a portion of the traversable network. A cost is assigned to the lane based on the at least one dynamic parameter corresponding to the lane. A routing or navigation function is performed using the cost assigned to the lane and the lane level network graph to generate routing information. The routing information is provided such that a mobile apparatus receives the routing information.

Abstract: An approach is provided for an unknown moving object detection system. The approach, for instance, involves capturing a plurality of unknown object events indicating an unknown object detected by one or more computer vision systems. The approach also involves clustering the plurality of unknown object events into a plurality of clusters based on one or more clustering parameters. The approach further involves selecting at least one cluster of the plurality of clusters based on a selection criterion. The approach further involves determining at least one operating scenario for the one or more computer vision systems based on a combination of the one or more clustering parameters associated with the selected at least one cluster.
