Abstract: A system is disclosed for generating speed limit data. The system may include a memory configured to store computer executable instructions and one or more processor configured to execute the instructions to receive sign data relating to one or more traffic entities. The sign data comprises at least one of: a set of speed values, a set of transportation mode values, and one or more entity parameters associated with the corresponding one or more traffic entities. The processors are further configured to generate matching data based on a matching between the set of speed values and the set of transportation mode values, based on the one or more entity parameters. The processors are further configured to generate speed limit data based at least on: the matching data, the sign data and a predefined condition associated with transportation mode.

Abstract: The disclosure provides a system, a method, and a computer program product for validating a road sign. The method comprises receiving at least one road sign observation associated with a location wherein the road sign observation comprises at least a road sign type. The method may include obtaining sensor data associated with the at least one road sign observation, based on at least the road sign type. The method may include calculating a number of lanes based on the sensor data. The method further includes, validating the road sign based on the number of lanes, wherein the road sign is validated as a correct road sign when the number of lanes is less than the number of lanes obtained from map data associated with the location.

Abstract: A method, apparatus, and user interface for providing a roadworks location detection system is disclosed. For example, image data of at least one roadworks sign may be obtained and a location for the roadworks project may be determined based on the obtained image data. One or more road segments may then be identified, and the determined roadworks location associated with the one or more identified road segments to update a map layer of a geographic database and/or perform other actions.

Abstract: Embodiments described herein may provide a method for identifying the location of a hazard, evaluating how long that hazard is likely to be present at the location, and providing an indication of the time to live of the hazard. Methods may include: receiving an indication of a hazard event, where the hazard event includes a timestamp and a location; map matching the location of the hazard event to a map-matched road segment; determining a time to live of the hazard event based, at least in part, on the timestamp and the map-matched road segment; providing an indication of the time to live of the hazard event as at least one of a database entry or a map user interface element; and providing for at least one of route guidance or navigational assistance based, at least in part, on the time to live of the hazard event.

Abstract: A method, a system, and a computer program product may be provided for updating map data in a map database to indicate presence of a road sign. The method may include obtaining first sensor data associated with a road sign. The first sensor data may comprise at least one of one or more first positive observations of a road sign or one or more first negative observations of the road sign. The method may further include obtaining second sensor data for the road sign, for example, based on the first sensor data. The second sensor data may comprise cumulative historic road sign observation data for time duration. The method may include determining a sign confidence ratio based on the first sensor data and the second sensor data. The method may include updating the map data based on the sign confidence ratio.

Abstract: An approach is provided for detecting a presence of a physical divider on a road segment. The approach, for example, involves determining a number of positive observations of the physical divider on the road segment based on sensor data collected from one or more vehicles traveling the road segment. The approach also involves determining a number of negative observations of the physical divider on the road segment based on the sensor data. The approach further involves calculating a probability of the presence of the physical divider based on the number of the positive observations and the number of the negative observations. The approach further involves updating map data for the road segment to indicate the presence of the physical divider based on determining that the probability of the presence of the physical divider is greater than a threshold value.

Abstract: An approach is provided for interpolating weather forecast reports for a forecast location having limited weather station access. The approach involves segmenting a plurality of weather forecast reports according to a plurality of segmentation categories, the plurality of segmentation categories representing respective one or more forecast parameters. The approach also involves determining respective values of the plurality of segmentation categories from each of the plurality of weather forecasts. The approach further involves selecting a representative value from the respective values for each of the one or more segmentation categories. The approach further involves combining the representative value for said each of the plurality of segmentation categories to generate an interpolated weather forecast report.
