Traffic signal control systems and traffic signal control devices and traffic signal control method

摘要

PROBLEM TO BE SOLVED: To provide a traffic light control system allowing flexible and high-level operation.;SOLUTION: In the traffic light control system, a pattern of traffic light control parameters corresponding to present time is selected by use of a first pattern switching table used in a conventional time-controlled pattern selection method, and thereafter, a pattern is reselected by use of a newly provided second pattern switching table. In the second pattern switching table, a calling condition for selecting the set pattern is set, and the pattern set in the second pattern switching table is selected instead of the pattern selected in the first pattern switching table when a calculated traveling time accords with the calling condition.;COPYRIGHT: (C)2012,JPO&INPIT
