Abstract: An approach is provided for determining probe data generated by a device travelling on a road segment is for pedestrian travel. A lane matching platform determines a speed of a probe point. The lane matching platform also determines a spatial distance of the probe point from a center line vector of a road segment. The lane matching platform also determines an allowed transport mode for the road segment. The lane matching platform further identifies the transport mode of the probe point based on the speed, the location of the probe point with respect to the center line, and the allowed transport mode. The transport mode, the allowed transport mode, or a combination thereof includes a car transport mode or a pedestrian transport mode.

Abstract: In an example embodiment, a plurality of sequences of instances of probe data are received. Each sequence of instances of probe data is captured and provided by a probe apparatus comprising a plurality of sensors and is onboard a vehicle. An instance of probe data comprises location information indicating a location of the corresponding probe apparatus and the instances are ordered by capture time to form the sequence of instances. A travel direction of each probe apparatus is determined based on the corresponding sequence. Each probe apparatus is matched to a lane of a road segment based on the determined travel direction and a predetermined vehicle lane pattern. The vehicle lane pattern comprises at least one reversible lane. Probe apparatuses matched to the at least one reversible lane are identified. An active direction is determined based on the number of identified probe apparatuses corresponding to each travel direction.

Abstract: An approach is provided for determining tunnel speed for a vehicle travelling through a tunnel. A tunnel processing platform aggregates probe data associated with at least one vehicle into at least one tunnel path based, at least in part, on a network geometry topology for at least one tunnel. The tunnel processing platform also designates at least one probe point collected upstream of the at least one tunnel as at least one starting point of the at least one tunnel path and at least one temporary probe point as at least one endpoint of the at least one tunnel path, wherein the at least one temporary probe point is downstream of the at least one tunnel. It then determines at least one temporary tunnel speed for the at least one tunnel path based, at least in part, on the timestamp for the at least one probe point and the current time associated with the at least one temporary probe point.

Abstract: A method, apparatus and computer program product are provided to improve the identification and characterization of split lane traffic and other multi-modality traffic conditions. In the context of a method, multimedia data from a camera is received that is representative of traffic conditions along a road segment upstream of a junction. The method identifies a multi-modality condition along the road segment upstream of the junction based upon an analysis of the multimedia data. The method also includes evaluating a plurality of probe points representative of travel along the road segment upstream of the junction in accordance with a detection algorithm to separately determine whether the multi-modality condition exists along the road segment upstream of the junction. The method further includes determining whether to modify one or more tuning parameters of the detection algorithm based upon the multi-modality condition identified based upon the analysis of the multimedia data.

Abstract: A method is provided to generate vehicle lane speed patterns. A method may include: receiving probe data from a plurality of probes, where the probe data includes probe data point location and heading; matching probe data points to a road segment to generate map-matched probe data points; analyzing the probe data relative to the road segment to establish a multi-modal distribution of probe data representing a distance of the probe data points from a pre-defined reference position of the road segment; matching the analyzed probe data points to individual lanes of the road segment, where peaks in the established multi-modal distribution are associated with individual lanes; and generating a vehicle lane speed pattern for each lane of the road segment based on a speed associated with probe data that is map-matched to the individual lanes.

Abstract: A method, apparatus and computer program product are provided to identify a split lane traffic location. In a method, a distribution of speeds associated with a plurality of historical probe points representative of travel along a road segment upstream of diverging downstream road segments is determined for each of a plurality of epochs. For each epoch, the distribution is evaluated to cluster the speeds associated with the plurality of historical probe points during the respective epoch into higher and lower speed clusters. For each epoch, it is determined whether a bi-modality condition exists upstream of the diverging downstream road segments based upon a relationship between the higher speed and the lower speed during the respective epoch. A split lane traffic location is then identified based upon a bi-modality frequency with which a bi-modality condition is determined from the historical probe points associated with the plurality of epochs.
