  • Patent number: 11072338
    Abstract: An approach is provided for road curvature data. The approach, for example, involves segmenting a road segment or plurality of road segments into a plurality of slices. The approach also involves retrieving location trace data for the plurality of slice. The location trace data, for instance, is collected from one or more location sensors of a plurality of vehicles traversing the plurality of slices. The approach further involves computing respective curvatures for the plurality of slices based on the location trace data. The approach further involves providing the road curvature data for the road segment of plurality of road segments (e.g., comprising an intersection) based on the respective curvatures of the plurality of slices.

  • Patent number: 10928521
    Abstract: Systems and methods for using a plurality of probe reports to augment a geographic database with traffic volume data. The plurality of probe reports are identified for a road segment for a time period. A probe value is determined for the road segment for the time period based on the plurality of probe reports. A probe probability value is calculated for the road segment for the time period based on the probe value. The probe probability value is adjusted using road attributes. The adjusted probe probability value is used to estimate traffic volume. The geographic database is augmented with the estimated traffic volume.

  • Publication number: 20200400439
    Abstract: An approach is provided for identifying a map error. The approach, for example, involves determining a first road curvature for a map location based on a road geometry represented in digital map data. The approach also involves determining a second road curvature for the map location based on location trace data collected from one or more location sensors of a plurality of vehicles. The approach further involves flagging the road geometry represented in the digital map data based on determining that a difference between the first road curvature and the second road curvature exceeds a threshold. The approach then involves providing the flagged road geometry as an output for identifying the map error.

  • Patent number: 10657804
    Abstract: Apparatus and methods are described for updating a geographic database based on road object probabilities. For example, an initial value set for an existence probability that a road object exists is determined. Observation data collected from sensors of vehicles are received. A total quantity of the observation data include a first quantity of vehicles that observed a presence of the road object and a second quantity of the vehicles observed an absence of the road object. A presence probability indicative of a likelihood that observation data accurately describe the road object and an absence probability indicative of a likelihood that observation data accurately describe the road object are calculated to determine an updated value for the existence probability. A geographic database is updated in response to the comparison of the updated value for the existence probability to a threshold confidence level.

  • Patent number: 10366612
    Abstract: Systems, methods, and apparatuses are provided for determining an optimal warning distance for a vehicle. For example, the geographic location of the vehicle is received along with a reaction profile of the operator of the vehicle. Based on the geographic location, a roadway condition is determined. An optimal warning distance is then determined based on a braking distance of the vehicle and the reaction profile of the operator of the vehicle. The operator of the vehicle, or a navigation system of the vehicle itself, is alerted to the roadway condition when the vehicle is located at the optimal warning distance.

  • Patent number: 10311728
    Abstract: An approach is provided for a confidence-based road event message. For example, the approach involves aggregating road event reports (e.g., slippery road event reports) from vehicles traveling in an area of interest. The approach also involves retrieving weather data records for the area of interest for a time period corresponding to the reports. The approach may further involve determining a data freshness parameter based on an age of the reports, and a number of vehicle generating the reports. The approach further involves calculating a confidence level for the road event based on the weather data records, data freshness parameter, number of the one or more vehicles, or a combination thereof.
