Abstract

An abnormality detection device of an embodiment includes a traffic control center device to detect an abnormality of vehicle detectors installed in a road network, including: a first traffic management unit that collects detector information including measurement quantities from the vehicle detectors; a statistical processing unit that statistically processes the measurement quantities for each designated period to generate statistical information including statistical values of the measurement quantities; a map information generating unit that generates, based on the statistical values of the measurement quantities of the vehicle detectors that already have been determined to be abnormal by a user, map information representing a distribution situation of the statistical values of the measurement quantities in an abnormal state; and a detector state determination unit that determines, based on the measurement quantities of each vehicle detector to be assessed and the map information in the abnormal state, whether the vehicle detector is abnormal.
