Firstly,　the　synergetic　theory　and　the　basic　method　of　synergetic　pattern　recognition　was　studied.　Secondly,　some　problems　exiting　in　the　automatic　recognition　methods　based　on　the　synergetic　method　of　traffic　states　was　discussed　and　a　resolution　of　the　intelligent　traffic　control　system　was　presented.　Lastly,　a　simulation　example　of　intelligent　traffic　control　on　two　crossings　was　given.　The　simulation　results　showed　that　the　application　of　the　synergetic　method　on　the　field　of　traffic　state　recognition　is　successful,　in　which　the　length　of　the　car　line　around　the　crossing　is　reduced　in　the　intelligent　traffic　control　system.
