CONGESTION-NAMING DEVICE AND CONTROL METHOD

摘要

A congestion-naming device comprises a congestion-detecting means, a cause-identifying means, and a naming means. The congestion-detecting means detects the occurrence of congestion. The cause-identifying means identifies the name of the location that is the cause of the congestion detected by the congestion-detecting means. The naming-means names the detected congestion, using the identified name of the location as a basis.
