    Abstract: System and methods for detecting and obtaining lane level insight in unplanned incidents. Probe-based vehicles and lane-level insight using a lane-level map-matcher are used to acquire information. This information is aggregated and used to differentiate lane activity in terms of traffic and safe navigation. With the identification of probes per-lane and probe speeds per-lane, sudden reductions in probe speeds may be obtained at a lane-based level. This is used to verify or detect lane-level incident or hazard warnings and consequently alert a driver to safer navigation paths ahead of time, for example alerting the driver to maneuver to a different lane or to take an alternative route.

    Abstract: System and methods for real-time lane level traffic processing. A lane level map matcher is used to map match probe data from probes to the lane level. A lane level travel time aggregator determines an optimal method to allocate travel-time per-link for a probe trajectory that traverses at least one lane. A lane aggregator aggregates the probe trajectories and probe-path speeds per-lane and obtain the representative speed for the lane.

    Abstract: A method, apparatus and computer program product are provided to determine lane statuses such as closures and/or shifting, by using probe data, such as probe data collected from vehicle and/or mobile devices traveling along a road segment. Probe data collected in real-time or near real-time is compared to historical probe data to determine differences in lateral positional indicators of vehicles along a route. The determined lane status may further include a direction of lane shift or lateral offset, indicator of which lane is closed, and/or shifted, and/or an indication of a lane associated with a leftmost and/or rightmost shift, and an indication of a lane associated with the largest shift. Notifications of detected lane statuses may be provided to drivers and/or other systems or users.

    Abstract: Systems, methods, and apparatuses are disclosed for predicting or estimating the value of a variable speed sign (VSS). Probe data is received from multiple vehicles associated with a road segment. Location values are derived from the probe data. Center distance values are calculated based on the location values and the road segment. Clusters are derived from the probe data. Center distance values are grouped according to the respective clusters and a lane is assigned to at least one cluster based on the center distance values. The speed of the cluster predicts or estimates the corresponding lane of the VSS.

    Abstract: Systems, methods, and apparatuses are provided for measuring quality in optimal navigation routes. A plurality of nodes having latitude and longitude coordinates is received for analysis. The nodes may be map matched with a road network and a traveled route of the navigation device may be determined. Alternative routes may be calculated between the origin and destination of the traveled route at a time after the traveled route is completed. Comparisons may be made between the traveled route and the alternative routes. The comparison data may be used to develop an improved traffic database or the data may be reported to a navigation device or navigation service provider.

    Abstract: Systems, methods, and apparatuses are disclosed for predicting the value of a variable speed sign (VSS) and determining the predicted value's associated confidence level. Highly assisted driving (HAD) vehicles may read or capture images of the VSS. The speed limit values, images, or videos of the VSS are reported and received by a network and database for analysis. A predicted speed limit value is determined for the variable speed sign from at least a portion of the received traffic data. A confidence level is also calculated for the predicted speed limit value for the variable speed sign.

    Abstract: Systems, methods, and apparatuses are disclosed for predicting or estimating the value of a variable speed sign (VSS). A variable speed sign is identified. Probe data is collected at one or more vehicles in proximity to the variable speed sign. The speeds of the vehicles are included in or derived from the probe data. A statistical analysis is performed on the probe data. A speed limit value for the variable speed sign is determined based on the statistical analysis.

    Abstract: A controller receives probe data from a vehicle traveling on a path segment. The probe data may be collected by a mobile device. The path segment may be a multilane roadway. The controller identifies a first lane of the path segment from the probe data. The controller associated a forked route with the first lane of the path segment. The controller calculates different traffic values for the lanes of the path segment. One traffic value may be calculated directly from speeds derived from the path data. Another traffic value may be calculated by the probe data and a historical relationship.
