Abstract: An approach is provided for traffic data blending based on road segment travel time reliability during traffic prediction. The approach involves, for instance, retrieving real-time traffic information and/or historical traffic information for each road segment within a geographic area. The approach also involves aggregating traffic flow speed data in the real-time traffic information to compute traffic pattern data for each road segment. The traffic pattern data includes static speed data of each said road segment. The approach further involves aggregating traffic flow speed data in the historical traffic information to compute travel time reliability index metric(s) for each said road segment. The approach further involves determining, based on the travel time reliability index metric(s), to use the traffic pattern data, a mean, or a percentile of a road segment travel time distribution in the historical traffic information for traffic prediction associated with each said road segment.

Abstract: An approach is provided for providing hybrid traffic incident identification. The approach, for example, involves processing traffic incident information received from at least one incident source to classify the traffic incident information as either well-formatted data (matching at least one previously stored incident code) or non-well-formatted data (not matching the previously stored incident code). The approach also involves converting the well-formatted data to an incident reporting format to generate a first output portion. The approach further involves extracting incident content from the non-well-formatted data. The extracted incident content represents the traffic incident information based on the at least one previously stored incident code. The approach further involves converting the extracted incident content to the incident reporting format to generate a second output portion. The approach further involves providing the first output portion and/or the second output portion as a hybrid incident output.

Abstract: A system, a method, and a computer program product may be provided for generating traffic congestion estimation data of one or more lanes in a region. A system may include a memory configured to store computer program code and a processor configured to execute the computer program code to obtain image data associated with the region. The processor may be configured to determine a count of one or more first movable objects in one or lanes, based on image data, calculate a lane object static capacity of the one or more lanes, based on one or more map free flow or speed limit attributes associated with the one or more lanes and generate the traffic congestion estimation data based on count of first movable objects in the one or more lanes, the moving speed of movable objects crossing multiple image frames, the lane object static capacity of lanes.

Abstract: The disclosure provides a system, a method, and a computer program product for validation of sensor data. The system may be configured to receive sensor data associated with a hazard. The sensor data may include at least a first time of occurrence of the hazard. The system may be further configured to determine a second time of occurrence of the hazard based on a time-space diagram associated with one or more vehicles that passed through a location of the occurrence of the hazard. The system may further calculate a validation result for the received sensor data based on a comparison of the first time of occurrence and the second time of occurrence, and an associated first predefined threshold.

Abstract: Embodiments described herein may provide a method for aggregating probe data to detect a road work event and generating, from the road work event, a work zone map overlay to inform navigational systems and autonomous vehicles. Methods may include: receiving probe data from a plurality of probe apparatuses traveling within a road network; identifying, from the probe data, a road work event within the road network; determining, from the road work event and the probe data, a work zone; generating a map overlay including the work zone, where the map overlay is independent from map data of the road network; providing the map overlay to at least one vehicle for use in combination with the map data of the road network; and providing for at least one of navigational assistance or at least semi-autonomous vehicle control based on the map overlay of the map data of the road network.

Abstract: An approach is provided for providing a recommended route and departure time combination based on real-time estimated times of arrival (ETAs). The approach, for example, involves determining a plurality of candidate routes between an origin and at least one destination. The approach also involves retrieving real-time information, historical information, predicted information, or a combination thereof associated with the origin, the destination, the plurality of candidate routes, or a combination thereof. The approach further involves calculating respective cost values (e.g., ETAs) for traveling for the plurality of candidate routes at a plurality of different departure times. The respective cost values are based on the real-time information, the historical information, the predicted information, or a combination thereof. The approach further involves determining a recommended route and departure time combination based on the respective cost values. The approach further involves providing the recommended route and departure time combination as an output.

Abstract: A system, a method, and a computer program product may be provided for generating navigation instructions. The system may include a memory configured to store computer executable instructions and a processor configured to execute the computer executable instructions to retrieve sensor data associated with at least one vehicle travelling along a route having at least one intersection and map data associated with the route from a map database. The sensor data indicates intersection information relating to the at least one intersection. The intersection information comprises an intersection category and an intersection type. The map data comprises traffic-related information for a plurality of intersection connected links. The processor may be further configured to determine a turn cost correction factor for the at least one intersection, based on the sensor data and the map data. The processor may be further configured to store the turn cost correction factor within the map database.

Abstract: The disclosure provides a system, a method, and a computer program product for updating map data. The system, for example, obtains sensor data from one or more user equipment. The sensor data is associated with a road object. Further, the system, determines a first location of a road observation sight and a second location of the road object based on a timestamp associated with the first location. Further, a distance associated with the second location of the road object and a center point of a link, is calculated. The link is a map matched link associated with the second location. Further, the system updates the map data based on the calculated distance.

Abstract: An approach is provided for providing traffic based location referencing with offsets for road incident reporting. The approach, for example, involves determining a road incident that crosses at least one boundary between a first road segment and a second road segment. The approach also involves creating an aggregated road segment comprising a start location of the road incident in the first road segment to the boundary and from the boundary to an end location of the road incident in the second road segment or an end road segment. The approach further involves providing a report of the road incident that is referenced to a positive offset from the start location of the road incident to a beginning of the first road segment and/or a negative offset from the end location of the road incident to an end of the second road segment or the end road segment.
