Abstract: Systems and methods for determining a cause of a change in driver assistance capability may be based on probe data generated by a mobile device or vehicle. The probe data is matched to a path segment. A cause of the change in driver assistance capability for the path segment is determined based on the probe data matched to the path segment. A geographic database record including the cause of the change in the driver assistance capability is output.

Abstract: A method, apparatus and computer program product are provided for generating speed profiles for autonomous vehicles in safety risk situations for a road segment. In this regard, a road segment associated with a safety risk profile is identified based at least in part on road condition data related to the road segment. Furthermore, probe data is obtained from one or more probe apparatuses traveling along the road segment associated with the safety risk profile. Based at least in part on the probe data, a speed profile for modeling velocity of autonomous vehicles along the road segment is generated. Additionally, an indication of the speed profile is provided to one or more autonomous vehicles to facilitate navigation of the one or more autonomous vehicles along the road segment.

Abstract: An approach is provided for detecting lane-level dangerous slowdown events based on probe data and/or sensor data. The approach, for example, involves splitting probe data, sensor data, or a combination thereof into at least one vehicle trajectory, wherein the data is collected from one or more vehicles traveling on a road segment. For each vehicle trajectory of the at least one vehicle trajectory, the approach also involves processing said each vehicle trajectory to detect a slowdown event based on a speed reduction greater than a threshold reduction. The approach further involves classifying a slowdown event type of the slowdown event based on a final driving location, a final driving speed, or a combination thereof of the at least one vehicle trajectory. The approach further involves providing the slowdown event, the slowdown event type, or a combination thereof as an output for the road segment.

Abstract: Systems and methods for vehicle routing may be based on wireless network performance data. A vehicle route includes one or more path segments included in the route based on the wireless performance data. The vehicle route may be updated based on updated wireless performance data. Driving assistance features of a vehicle may be enabled by the wireless performance data, and different driving assistance features may be enabled or disabled on the vehicle route according to changes in wireless performance data. As the vehicle traverses the route, the driving assistance features may be enabled or disabled based on the wireless performance data for the path segment. The vehicle route may be updated to continue to enable a set of the driving assistance features.

Abstract: Dynamic intersection map data is generated and provided. Traffic data is analyzed to identify an event. Responsive to identifying or receiving traffic data indicative of the event, it is determined whether the event affects one or more ingress or egress lanes of an intersection. Responsive to determining that the event affects at least one ingress or egress lane of an intersection, updated map data is generated for the intersection by updating map data corresponding to the at least one ingress or egress lane and, based on connection information corresponding to the at least one ingress or egress lane, further updating map data corresponding to one or more other lanes of the intersection. The updated map data is provided such that at least one vehicle apparatus receives the updated map data. The at least one vehicle apparatus uses the updated map data to perform one or more navigation functions.

Abstract: A method, apparatus and computer program product are provided for defining a geo-defense area related to presence of a roadworker entity. In this regard, a roadwork event related to a roadwork zone region of a road segment is identified based at least in part on one or more probe apparatuses traveling along the road segment. Furthermore, presence of at least one roadworker entity within the roadwork zone region is detected based at least in part on sensor data from the one or more probe apparatuses. Based at least on part on map data related to the roadwork zone region and location data related to the roadworker entity, a geo-defense area related to the roadworker entity is defined. Additionally, an indication of the geo-defense area is provided to one or more autonomous vehicles to facilitate navigation of the one or more autonomous vehicles along the road segment.

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: A method, apparatus and computer program product are provided to estimate the location of a vehicle based at least in part upon two or more road signs that are depicted by one or more images captured by one or more image capture devices onboard the vehicle. By relying at least in part upon the two or more road signs, the location of the vehicle may be refined or otherwise estimated with enhanced accuracy, such as in instances in which there is an inability to maintain a line-of-sight with the satellites of a satellite positioning system or otherwise in instances in which the location estimated based upon reliance on satellite or radio signals is considered insufficient. As a result, the vehicle may be navigated in a more informed and reliable manner and the relationship of the vehicle to other vehicles may be determined with greater confidence.
