Abstract: An approach is provided for identifying and characterizing mobile work zones (e.g., roadway striping, pothole filling, tree trimming, etc.). The approach, for example, involves processing probe data at a lane level to determine at least one forward forming shockwave associated with a congestion front of a mobile roadwork zone on at least one lane. The approach also involves providing data indicating the mobile roadwork zone as an output. The approach further involves determining a propagation rate of the mobile roadwork zone. The approach further involves determining a congestion recovery speed, where the congestion is caused by the mobile roadwork zone.

Abstract: An approach is provided for detecting lane departure events based on map data and probe data. The approach, for example, involves map-matching probe data to a lane of a road segment. The probe data is collected from one or more sensors of at least one vehicle and/or at least one user device that traversed the road segment. The approach also involves processing the probe data to detect at least one lane departure event. The approach further involves categorizing the at least one lane departure event as an intentional lane departure event or an unintentional lane departure event. The approach further involves creating a lane departure warning message for the road segment based on the at least one categorized lane departure event, and/or road segments associated with multiple lane departure warning messages within a certain time period. The approach further involves providing the lane departure warning message 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.

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.
