Abstract: An approach is provided for map matching a vehicle path network to a road topology network of a digital map. The approach, for instance, involves aggregating vehicle trajectory data into a vehicle path network that is a directed graph comprising a plurality of nodes. The approach also involves segmenting the vehicle path network into a plurality of linear features. Each linear feature of the plurality of linear features connects two nodes of the plurality of nodes in the vehicle path network. The approach further involves using a path-based map matcher to separately match each linear feature by incorporating context of the vehicle path network to a map topology of a digital map to generate map matching results. The approach further involves aggregating the map matching results of each linear feature into an overall map matching result for the directed graph, and providing the overall map matching result as an output.

Abstract: An approach is provided for an electric vehicle navigation system. For example, a destination is received as input. A geographic database is accessed to obtain data that represents a first road segment of a route to the destination. The data of the first road segment includes a first elevation coefficient of energy consumption associated with a first elevation change. The geographic database is accessed to obtain data that represents a second road segment of the route. The data of the second road segment includes a second elevation coefficient of energy consumption associated with a second elevation change. The first elevation coefficient is different than the second elevation coefficient. Energy consumption by the vehicle along the route is calculated based on the first elevation coefficient and the second elevation coefficient. Data representing energy consumption for the route is outputted as a function of the calculated energy consumption.

Abstract: A method, apparatus and computer program product are provided to automatically detect changes in width of road segments in real-time or near real-time 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 partitioned in order to identify width-defining portions of the probe data. The width-defining portions may be representative of the laterally-extreme lanes of the road segment, such as the left-most lane and the right-most lane. The width-defining portions are compared to corresponding width-defining portions of historical probe data to determine measures indicative of whether a road segment has expanded or narrowed. Indications of detected segment width changes may be provided to drivers and/or other systems or users. For example, map data for the road segment may be updated to reflect a detected width expansion or narrowing of the road segment.

In one example, an apparatus divides a zone into a plurality of subregions and causes a machine learning model to output a probability of which an EVCU is needed at each of the plurality of subregion based on one or more attributes associated with the subregion. The apparatus generates one or more clusters within the zone, where each of the one or more clusters include one or more of the plurality of subregions. The apparatus calculates a value for each of the one or more clusters based on the probability associated with each subregion within said cluster. The apparatus selects one of the one or more clusters based on the value and assigns a location within the one of the one or more clusters for deploying the EVCU.

Abstract: An approach is disclosed for verifying a lane closure using probe data. The approach involves, for example, receiving probe data collected from a probe device traveling a road link. The approach also involves performing a spatial clustering of the probe data with respect to a longitudinal axis of the road link.

The approach also involves detecting a lane closure on the road link based on determining that the cluster shift is greater than a shift distance threshold. The approach further involves providing the detected lane closure as an output.
