Abstract

An approach is provided for detecting road closures programmatically by monitoring probe activity. The approach, for example, involves generating a historical model of expected probe activity on the road segment based on historical probe data. The approach also involves monitoring observed probe activity from the road segment. The approach further involves calculating a probability of the observed probe activity based on the historical model of the expected probe activity. The approach further involves determining the closure status of the road segment based on the probability.
