TRAFFIC MONITORING DEVICE, TRAFFIC MONITORING SYSTEM, TRAFFIC MONITORING METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM WITH PROGRAM STORED THEREON

摘要

Provided is a traffic monitoring device with which congestion across an entire city can be resolved efficiently by the effective use of limited physical and human resources. The traffic monitoring device (10) has a vehicle information acquisition unit (11), a congestion determination unit (13), and a priority calculation unit (16). The vehicle information acquisition unit (11) acquires, from data received from each of a plurality of detection devices (20), vehicle information pertaining to the travel state of vehicles present in the vicinity of each of a plurality of intersections. On the basis of the vehicle information the congestion determination unit (13) determines whether congestion is occurring at each of the plurality of intersections, and determines that an intersection at which congestion is occurring is a congested intersection. The priority calculation unit (16) calculates a priority for implementing a countermeasure for resolving the congestion for each of a plurality of continuous congested routes, on the basis of at least the direction in which vehicles are advancing in the continuous congested route.
