Abstract: An approach is provided for speculative navigation routing in incomplete maps. The approach involves, for example, generating an offline navigation route to a destination using offline map data cached at a device. The approach also involves transmitting a routing request to a routing server for an online navigation route to the destination. The approach further involves providing the online navigation route or a portion of the online navigation route based on determining that the online navigation route or the portion of the online navigation is received within a timeout period. The approach further involves providing the offline navigation route or a portion of the offline navigation route generated during the timeout period based on determining that the online navigation route or the portion of the online navigation route is not received before the timeout period ends.

Abstract: An approach is provided for generating parking occupancy data using a machine learning model. The approach involves determining one or more classification features of a road link. The approach also involves processing the one or more classification features using the machine learning model to match the road link to a link category. The approach further involves determining a parking occupancy pattern for the road link based on the link category. The approach further involves creating or updating a parking occupancy record of a geographic record corresponding to road link using the parking occupancy pattern.

Abstract: Provided herein is a method of estimating a travel time along a route. Methods may include: obtaining a route between an origin and a destination, where the route includes a plurality of road links; identifying a subset of road links of the plurality of road links; providing an identification of each road link of the subset of road links to a service provider; receiving an indication of a pace of travel along each of the subset of road links; computing an estimated travel time along the route based on the pace of travel along each of the subset of road links; and providing an estimated time-of-arrival at the destination based on an identified departure time and the estimated travel time along the route. Methods may include computing an estimated travel time error along the route, and providing the estimated travel time error as a potential error of the estimated time-of-arrival.

Abstract: An approach is provided for representing an aerial route in a three-dimensional (3D) space. The approach, for example, involves determining a root 3D shape encompassing an aerial route through a 3D space. The 3D space is partitioned into a hierarchy of 3D shapes, and the aerial route comprises a list of 3D shape identifiers (IDs) corresponding to the 3D shapes that form the aerial route. The approach also involves recursively comparing a respective 3D shape ID of the root 3D shape or child shapes of the root 3D shape to the list of 3D shape IDs of the aerial route. The approach further involves generating a traversal command list by selectively adding the respective 3D shape ID that matches a 3D shape ID of the aerial route or includes the 3D shape ID as a child 3D shape ID. The approach further involves providing the traversal command list as an output.
