Traffic monitoring apparatus, traffic monitoring system, traffic monitoring method, and non-transitory computer readable medium storing program

Abstract

A traffic monitoring apparatus () includes a vehicle information acquisition unit (), a congestion determination unit (), and a priority calculation unit (). The vehicle information acquisition unit () acquires, from data received from each of a plurality of detection apparatuses (), vehicle information regarding travelling states of vehicles that are present in the vicinity of a plurality of respective intersections. The congestion determination unit () determines, for each of the plurality of intersections, whether or not congestion is occurring based on the vehicle information and determines an intersection where the congestion has occurred to be a congested intersection. The priority calculation unit () calculates, for each of the plurality of continuous congestion paths, a priority level for implementing measures to eliminate congestion based on at least the vehicle travelling direction in the continuous congestion path.
