Abstract: Systems, methods, and apparatuses are described for monitoring and visualizing traffic surprises. Traffic data is received for a region of interest comprising one or more routes. A surprise factor may be calculated for one or more routes in the region of interest based on a ratio of historical traffic data and real-time traffic data. A comparison may be performed of the surprise factor to at least one threshold. A surprise traffic message may be generated based on the comparison.

Abstract: In one embodiment, road segments are aggregated for DLR. A plurality of connected road segments and corresponding traffic information for each of the connected road segments are identified. A processor aggregates the connected road segments into a fewer number of dynamic location reference (DLR) segments than the plurality. By testing different possible combinations, road segments with similar congestion are grouped. The processor calculates a traffic value for each of the DLR segments. Each traffic value is a function of the traffic information for the connected road segments of the respective DLR segment. An indicator of the aggregated DLR segment and the traffic value for at least one of the DLR segments is output.

Abstract: A plurality of instances of event data are received. Each instance of event data corresponds to a traffic event on a first segment and comprises an indication of at least one parameter characterizing travel of a vehicle along the first segment during the traffic event. Based on the plurality of instances of event data, a recurring event is identified. At least one representative parameter characterizing travel along the first segment during the recurring event is determined based on the two or more instances of event data corresponding to the recurring event. At least one element of a data structure is modified with the at least one representative parameter. The at least one element of the data structure corresponds to the first segment. A geographic database comprises the data structure and a navigation application is configured to use at least a portion of the data structure to perform a navigation function.

Abstract: An apparatus and method for determining a traffic level in the future. A road network including graph edges for a plurality of intersections and graph nodes for a plurality of road links is identified. A road link of interest is selected from the plurality of road links. A set of related link subset are calculated for the selected road link. Historical data is queried for the related link subset. A predicted traffic level is calculated for the selected road link in response to the historical data for the related link subset.

Abstract: One or more potential drone and/or flying car (DFC) corridors are identified based on the topology of a road network. Trajectories traveled by vehicles are determined from a plurality of instances of probe data received from a plurality of vehicle apparatuses onboard the vehicles. A volume of traffic for a path through the road network and corresponding to a potential DFC corridor is determined based on the trajectories. A delay metric for the path through the road network and corresponding to the potential DFC corridor is determined based on the trajectories. A traffic metric is then determined for the path based on a combination of the volume of traffic, the delay metric and a measure of the topology of the road network. The one or more potential DFC corridors are ranked by their corresponding traffic metrics.

Abstract: An apparatus for matching probe measurements to a path in a geographic location includes a receiver, a window manager, a location generator, a path calculator, and an output. The receiver is configured to receive a stream of probe measurements. The window manager is configured to fill a window with the measurements, to select an additional measurement from the stream, and to select an oldest measurement in the window. The location generator is configured to generate candidate locations for the measurements in the window and the additional measurement. The path calculator is configured to match the oldest measurement to a candidate location. The output is configured to output a path-matched probe measurement based on the oldest measurement and the candidate location matched to the oldest measurement.

Abstract: A method, apparatus and computer program product are provided for establishing direction based traffic events and lane-level traffic associated therewith. Methods may include receiving a plurality of probe data points, where each probe data point includes location information associated with the respective probe apparatus; determining a path through an intersection from among a plurality of paths through the intersection for each probe apparatus based, at least in part, on a sequence of probe data points from each respective probe apparatus; determining, for each path through the intersection, an average speed of probe apparatuses traveling along the respective path and an average travel time along a road link approaching the intersection of the probe apparatuses traveling along the respective path; and determining a direction based traffic event in response to the differential amount of time between the highest average travel time and the lowest average travel time.

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 providing lane-level connectivity data at an intersection. The approach involves, for example, retrieving probe data for an intersection with at least one upstream road link and at least one downstream link. The approach also involves performing a lane-level map-matching of the probe data to one or more upstream lanes of the at least one upstream road link, one or more downstream lanes of the at least one downstream link, or a combination thereof. The approach further involves generating a junction matrix for the intersection between the one or more upstream lanes of the at least one upstream road link and the one or more downstream lanes of the at least one downstream road link based on the lane-level map-matching of the probe data. The approach further involves determining lane-connectivity data for the intersection based on the junction matrix.

Abstract: A plurality of instances of probe data are received. Each instance of probe data corresponds to travel of a vehicle apparatus along a first segment, comprises an indication of at least one parameter characterizing the travel of the vehicle apparatus along the first segment. The at least one parameter is extracted from the instances of probe data to generate a distribution of parameters. One or more clusters of instances of probe data are identified based on the distribution of parameters. Responsive to identifying two or more clusters, a representative at least one parameter is determined for each cluster, and an element of a data structure is modified based thereon for each cluster. Responsive to identifying only one cluster of instances of probe data, the data structure is not modified based on the cluster. A navigation application is configured to use the data structure to perform a navigation function.
