CONGESTION MONITORING DEVICE, CONGESTION MONITORING METHOD, AND CONGESTION MONITORING PROGRAM

摘要

The present invention appropriately determines whether a congestion state in an area being monitored is normal or abnormal. A congestion monitoring device for monitoring traveler congestion in an area being monitored is provided with a congestion estimation unit for estimating a congestion index indicating a degree of congestion for each time period in each area arrived at by dividing the area being monitored, a congestion index management unit for retaining reference values for the congestion indexes in each time period in each area, a congestion index comparison unit for generating increase/decrease information indicating the increase/decrease of the congestion indexes in relation to the reference values, and an output unit for outputting notification information corresponding to the increase/decrease information.
