    Abstract: An approach is provided for automatically detecting a road closure during a probe anomaly. The approach, for example, involves determining a drop in an expected vehicle volume in a geographic area over a time epoch, wherein the expected vehicle volume represents an expected number of unique vehicles traveling in the geographic area over the time epoch. The approach also involves computing an adjusted expected vehicle volume for a road segment in the geographic area based on the drop and a historical expected vehicle volume for the road segment over the time epoch. The approach further involves determining a time window comprising at least the time epoch. The approach further involves performing an automatic road closure detection on the road segment using the time window.

    Abstract: An approach is provided for combining discontinuous road closures detected in a road network. The approach, for example, involves retrieving a roadway graph including one or more open segments and at least two discontinuous closed segments. The approach also involves computing an importance weight for road links of the segments of the roadway graph. The importance weight is based on one or more attributes of the road links. The approach further involves computing a closure confidence score for the one or more open segments and/or the at least two closed segments based on the importance weight and a link closure confidence score for each link. The approach further involves changing or not changing a road closure state of the open and/or closed segments based on the closure confidence score and a minimum distance threshold between the at least two closed segments.

    Abstract: An approach is provided for providing probe anomaly detection. The approach, for example, involves determining an expected vehicle volume for a geographic region over a time epoch. The expected vehicle volume is calculated from historical vehicle volume data. The approach also involves determining an actual vehicle volume for the geographic region over the time epoch. The actual vehicle volume is based on current vehicle volume data collected from a plurality of vehicles traveling in the geographic region. The approach further involves computing a vehicle volume change based on the expected vehicle volume and the actual vehicle volume. The approach then involves providing the vehicle volume change as an indicator of a probe anomaly in the geographic region.

    Abstract: An approach is provided for verification of a road closure. The approach, for example, involves generating a road graph comprising a road links associated with a road closure detected by a road closure detection system. The road closure detection system stores probe data for the road links collected over respective detection dynamic time windows. The approach also involves extracting respective verification dynamic time windows for the road links that are used by a road closure verification system to verify the road closure. The approach further involves filling the respective verification dynamic time windows using the probe data stored by the road closure detection system. The approach further involves initiating a verification of the road closure based on the filled respective verification dynamic time windows.

    Abstract: An approach is provided for automatically verifying a road closure report. The approach, for example, involves determining one or more features of probe data collected from a plurality of vehicles traveling on a connected set of road links of a closure link graph. The closure link graph, for instance, comprises a road link indicated by the road closure report, one or more upstream links from the road link, one or more downstream links from the road link, or a combination thereof. The approach also involves evaluating a closure probability of the road link indicated by the road closure report based on the one or more features. The road closure report is then automatically verified based on the closure probability.

    Abstract: An approach is provided for verifying reported ramp closures. The approach involves, for example, processing a ramp closure report to determine reported ramp link(s) associated with the ramp closure report. The approach also involves constructing a ramp network comprising the reported ramp link(s) and other ramp link(s) connected to the reported ramp link(s). The approach further involves collecting probe data collected from one or more sensors of one or more vehicles traveling within the ramp network. The approach further involves identifying one or more driving patterns based on one or more vehicle paths determined from the probe data. The approach further involves performing a verification of a closure status of the reported ramp link(s) based on the one or more driving patterns. The approach further involves providing the verification of the closure status as an output.
