Abstract: The disclosure provides a method, a system, and a computer program product for predicting traffic information for at least one map tile area. The method comprises obtaining probe data and map attribute data for each of a plurality of road segments in the at least one map tile area. The method may include generating current traffic condition data for each of the plurality of road segments in the at least one map tile area based on the obtained probe data and the obtained map attribute data. The method may further include obtaining historical traffic pattern data associated with each of the plurality of road segments in the at least one map tile area. The method may further include generating a tile based traffic index (TTI) for the at least one map tile area based on aggregating the current traffic condition data and the historical traffic pattern data of the plurality of road segments in the at least one map tile area and providing TTI and predicting the traffic information for the at least one map tile area based on the generated tile based traffic index (TTI).

Abstract: An approach is provided for determining road work zone travel time reliability based on vehicle sensor data. The approach involves, for instance, aggregating telematic data generated by vehicles traveling within a geographic area, to detect a road work zone and/or active time period(s) thereof. The approach also involves identifying a start location and an end location of the road work zone. The approach further involves identifying a starting time point when one of the vehicles approaching the start location and an end time point when the vehicle passes the end location. The approach further involves calculating a time difference between the start and end time points as a travel time through the road work zone. The approach further involves aggregating the vehicle travel times, to compute work zone travel time reliability index(es) for the road work zone. The approach further involves providing the travel time reliability index(es) as an output.

Abstract: Embodiments described herein may provide a method for management of vehicles at intersections. Methods may include: receiving probe data from probe apparatuses proximate an intersection between two or more road segments; identifying a first vehicle approaching the intersection from the probe data; determining, for the first vehicle approaching the intersection, a safe stop distance, where the safe stop distance includes a distance to stop the first vehicle from a current speed of the first vehicle; generating a warning message in response to the safe stop distance of the first vehicle being greater than a distance of the first vehicle from the intersection; and providing the warning message to one or more other vehicles approaching, at, or within the intersection, where the warning message provides an indication that the first vehicle cannot safely stop before entering the intersection,

Abstract: A method, apparatus and computer program product are provided to estimate the location of a vehicle based at least in part upon one or more data objects obtained by one or more sensors onboard the vehicle. One or more road segment attributes may be determined for one or more road segment indicia identified by the one or more data objects and the location of the vehicle may be estimated based at least in part upon the one or more road segment attributes. Furthermore, one or more driving profiles associated with the estimated location of the vehicle may be accessed and one or more navigational instructions may be determined based at least in part on one or more driving profile attributes of the one or more driving profiles. As a result, the vehicle may be navigated in a more informed and reliable manner.

Abstract: A method, a system, and a computer program product are provided for predicting road closure in a region. The method comprises obtaining, probe data, such as sensor data, and map data, for the region. The method may include detecting a change in speed of a one or more vehicle on a road, based on the obtained probe data and the obtained map data for the region, wherein the change in speed is associated with a slowdown event associated with the one or more vehicles. The method may include identifying a vehicle event on the road based on the detected change in speed of the one or more vehicles, wherein the vehicle event is associated with a location corresponding to a matching trajectory of the one or more vehicles and predicting the road closure based on the identified vehicle event.

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: Systems and methods are provided for determining when a traffic signal associated with one or more paths through a road intersection is malfunctioning. Congestion prior to and subsequent to the road intersection is identified from a plurality of probe reports. A malfunctioning traffic signal is determined based on whether or not congestion is identified prior to and subsequent to the road intersection.

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.
