TRAFFIC SIGNAL CONTROL SYSTEM, TRAFFIC SIGNAL CONTROL APPARATUS, AND TRAFFIC SIGNAL CONTROL METHOD (AS AMENDED)

摘要

Provided is a traffic signal control system that can operate in a flexible and sophisticated manner by, after selecting a pattern of a traffic signal control parameter corresponding to the current time using a first pattern switching table that is used in a time-controlled pattern selection scheme, selecting again a pattern using an additional second pattern switching table, where a call condition for selecting a set pattern is set in the second pattern switching table, and by selecting the pattern set in the second pattern switching table in place of the pattern selected in the first pattern switching table if a calculated travel time matches the call condition.
