Abstract: An approach is provided for estimating a vulnerable road user count in real time or near real time. The approach, for example, involves collecting one or more vulnerable road user observations from at least one vehicle traveling a road link. The approach also involves querying a geographic database for historical vulnerable road user data for the road link. The approach further involves determining a first variance for the one or more vulnerable road user observations and a second variance for the historical vulnerable road user data. The approach further involves calculating the vulnerable road user count by fusing the one or more vulnerable road user observations with the historical vulnerable road user data based on the first variance and the second variance.

Abstract: A method, system, and computer program product is provided, for example, for identifying a type of road sign. The method may include receiving a plurality of observations for the road sign. The method may also include clustering the plurality of observations based on at least a location and a heading of the road sign. Further, the method may include filtering the plurality of observations in the cluster based on a speed value and a lateral offset of each of the plurality of observations. Also, the method may include identifying the type of the road sign based on the filtering.

Abstract: A method, apparatus and computer program product for determining a rain event warning are described herein. In the context of a method, an indication of the rain event warning for one or more locations may be received. The method may obtain, for a respective rain event warning, sensor data corresponding to a weather condition within a region that includes the location with which the respective rain event warning is associated. The method may evaluate the sensor data to determine whether the sensor data is indicative of the weather condition (e.g., rain). The method may determine a rain event warning confidence based at least in part on evaluation of the sensor data. The method may cause the rain event warning to be published in an instance in which the rain event warning confidence satisfies a confidence threshold.

Abstract: A system, a method, and a computer program product for generating updated map data are provided. The method comprises obtaining first sensor data associated with a plurality of first road signs within a geographic region, obtaining second sensor data associated with the geographic region, and determining a sign matching efficiency for the geographic region, based on the first sensor data and the second sensor data. The method further comprises generating the updated map data, based on the determined sign matching efficiency.

Abstract: An apparatus is configured to perform a method for generating warning polygons for weather events in a geographic region. The method includes receiving measurement data from one or more sensors, identifying at least one location from the measurement data, identifying a map tile within a predetermined distance to the at least one location, generating a map tile cluster based on analysis of the at least one map tile, accessing an end-use constraint of the end-use device, the end-use constraint indicative of a constraint in processing on the end-use device, and calculating the warning polygon based on the map tile cluster and based on the end-use constraint such that the polygon intersects the geographic region.
