Abstract: The disclosure provides a system, a method, and a computer program product for detecting active road work zones. The system obtains first sensor data associated with a detection of a road work zone, using a first sensor type and obtains second sensor data associated with presence of at least one individual in the road work zone, using a second sensor type. Further, the system determines a confidence level associated with the detection of the road work zone based on fusing of the first sensor data and the second sensor data. The system classifies the detected road work zone as at least one of the active road work zone or a non-active road work zone, based on the confidence level. The system updates map data associated with a map of a region based on the classification.

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: A system, a method, and a computer program product may be provided for determining dynamic road capacity data of one or more lanes of a road segment 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 probe data, historical capacity dynamic pattern data and event data. The processor may be configured to calculate road capacity data of the lane. The processor may be configured to calculate a count of movable objects in the lane. The processor may be configured to determine a traffic condition of the lane. The processor may be configured to determine the dynamic road capacity data based on the road capacity data, the count of one or more movable objects, the historical capacity dynamic pattern data and the traffic condition of the at least one lane of the road segment.

Abstract: A method, apparatus and computer program product are provided to selectively utilize one or more networks in order to reliably communicate the information regarding one or more traffic signals and one or more intersections controlled by respective traffic signals. In the context of a method, the method includes communicating with a first network in order to receive information with a mobile platform regarding one or more traffic signals and information regarding one or more intersections. At least one traffic signal is associated with a respective intersection. The method also includes identifying a first switching condition and communicating with a second network, different than the first network, in order to receive the information regarding the one or more traffic signals and the information regarding the one or more intersections following identification of the first switching condition.
