Abstract: A method, apparatus and computer program product are provided to predict a map object based at least in part on audio data. With respect to predicting a map object, audio data created by a vehicle while driving over a road surface is obtained. The audio data includes one or more audio amplitude features, one or more audio frequency features or a combination of audio amplitude features and audio frequency features. The audio data including the one or more audio amplitude features is provided to a machine learning model and the map object that created the audio data while the vehicle interacted therewith is predicted utilizing the machine learning model. A method, apparatus and computer program product are also provided for training the machine learning model to predict the map object based at least in part on audio data.

Abstract: A system, a method and a computer program product are provided for evaluating quality of data, such as sensor data and map data, using a machine learning model. The system may include at least one memory configured to store computer executable instructions and at least one processor configured to execute the computer executable instructions to obtain first sensor features of the first sensor data associated with a road object in a first geographic region, first map features of the first map data associated with the road object and ground truth data associated with the road object. The processor may be configured to generate the machine learning model by configuring the ground truth data and calculating first information scores for each of the first sensor features and the first map features by recursively splitting each of the first sensor features and the first map features.

Abstract: A system, method and computer program product are provided for generating ramp link data of a road in a region. In an example embodiment, the method may include obtaining map data of the region, wherein the map data comprises link data of a plurality of links in the region. The method may further include determining at least one link pair corresponding to the road from the map data of the region based on one or more of a link start criterion, a heading criterion, or an uplink criterion. The method may further include determining one or more attributes of each link of the obtained at least one link pair and generating the ramp link data of the road based on the one or more attributes of each link of the at least one link pair.

Abstract: The disclosure provides a method, a system, and a computer program product in accordance with at least one example embodiment for generating lane change action data for an autonomous vehicle. The solution includes a method of identifying one or more road objects and determining road object data. The method further includes determining drive condition data corresponding to an environment in which the autonomous vehicle is located. Furthermore, a step of generating lane change action data is triggered based on the determined drive condition data. The generated lane change action data instructs the autonomous vehicle on whether or not to change a lane in an overtake prohibition zone.

Abstract: An approach is provided for generating delivery data models for aerial package delivery. The approach involves determining at least one delivery surface data object to represent one or more delivery surfaces of at least one delivery location, wherein the one or more delivery surfaces represents at least one surface upon which to deliver at least one package. The approach further involves causing, at least in part, a creation of at least one complete delivery data model based, at least in part, on the at least one delivery surface data object to represent the at least one delivery location. The approach further involves causing, at least in part, an encoding of at least one geographic address in the at least one complete delivery data model to cause, at least in part, an association of the at least one complete delivery data model with at least one geographic location.

Abstract: A method, system, and computer program product is provided, for example, for generating heading information. The method comprises receiving a coordinate information for a gantry. The method further comprises receiving an identification information for a link associated with the gantry. Additionally, the method comprises extracting information related to one or more shape points associated with the link based on the identification information. Further, the method comprises matching the coordinate information for the gantry with at least two consecutive shape points from the one or more shape points, wherein the at least two consecutive shape points are closest from the gantry. Also, the method comprises calculating, by a processor, a heading value for the gantry based on the matching. The heading value for the gantry may be used to identify direction information for the gantry, which may further be used for updates.

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 assisting a user of the vehicle in following a prescribed speed limit while travelling in the vehicle. The method comprises providing a speed limit related recommendation to the user of the vehicle. The method further comprises receiving an image data representing a posted sign, in a vicinity of the vehicle, the image data being detected by one or more image capturing devices. Additionally, the method comprises processing the image data received to determine an observed numerical value. The method further comprises calculating, by a processor, a sign reliability factor based on a function of at least the observed numerical value, a historic mean of one or more vehicle speeds at the time of sign observation and a standard deviation of the one or more vehicle speeds at the time of sign observation. Additionally, the method may include providing data for an indication of the speed limit to be followed by the vehicle.

Abstract: An approach is provided for mapping vulnerable road users. The approach, for example, involves receiving sensor data from at least one vehicle indicating a presence of at least one vulnerable road user. The sensor data indicates a detected location of the at least one vulnerable road user. The approach also involves map matching the detected location of the at least one vulnerable road user to at least one road node, link, and/or a segment thereof of a geographic database. The approach further involves generating a vulnerable road user attribute to indicate a probability of the presence of the at least one vulnerable road user based on the sensor data. The approach further involves storing the vulnerable road user attribute in the geographic database as an attribute of the at least one road node, link, and/or segment.
