Abstract: An approach is provided for determining at least one distribution of a plurality of current values for at least one dynamic content parameter associated with a plurality of points of interest within a predetermined proximity to at least one target point of interest. The approach involves determining at least one distribution mean and at least one distribution standard deviation for the at least one distribution of the plurality of current values. The approach also involves determining at least one set of historical values for the at least one dynamic content parameter for the at least one target point of interest. The approach further involves determining at least one estimated current value for the at least one dynamic content parameter associated with the at least one target point of interest based, at least in part, on the at least one set of historical values, the at least one distribution mean, and the at least one distribution standard deviation.

Abstract translation: 提供了一种用于确定与至少一个目标感兴趣点的预定接近度内的与多个兴趣点相关联的至少一个动态内容参数的多个当前值的至少一个分布的方法。 该方法涉及确定多个当前值的至少一个分布的至少一个分布均值和至少一个分布标准偏差。 该方法还涉及为至少一个目标感兴趣点确定至少一个动态内容参数的至少一组历史值。 所述方法进一步包括至少部分地基于所述至少一组历史值来确定与所述至少一个目标兴趣点相关联的所述至少一个动态内容参数的至少一个估计当前值，所述至少一个动态内容参数 分布平均值，以及至少一个分布标准偏差。

Abstract: An approach is provided for publishing a road event message according to a hysteresis. For example, the approach involves processing a road report to determine a road event associated with a geographic location and a confidence metric of the road event. The approach also involves initiating a publishing of a road event message to indicate the road event for the geographic location based on determining that the confidence metric is greater than an upper threshold of a hysteresis. The approach further involves processing one or more other road reports to update the confidence metric of the road event. The approach further involves initiating a cancelling of the road event message based on determining that the updated confidence metric is less than a lower threshold of the hysteresis.

Abstract: An approach is provided for detecting false positive slippery road reports. For example, the approach involves receiving a slippery road report from a vehicle. The slippery road report, for instance, indicates that a slippery road event is detected at a location based on sensor information collected by the vehicle. The approach also involves map matching the location of the slippery road report to the mapping data to evaluate a proximity of the location to at least one geographic feature that is designated as an area where driver behavior is expected to be at least one cause of the slippery road event. The approach further involves classifying the slippery road report as the slippery road false positive report based on the evaluation.
