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.
