The　paper　presents　a　signal　control　strategy　of　urban　traffic　networks　(UTNs),　under　which　states　of　UTNs　can　realize　asymptotic　stable　consensus.　We　first　propose　a　simulation　model　of　UTNs,　where　the　topology　of　road　network　is　represented　by　a　directed　dynamic　graph,　and　the　transfer　of　underlying　traffic　flows　is　modeled　by　the　cell　transmission　model　(CTM).　Furthermore,　under　some　assumptions,　we　can　obtain　a　signal　control　model　of　UTNs,　which　is　a　discrete-time　linear　time-invariant　control　system,　and　then　design　a　state-feedback　control　law,　under　which　the　proposed　control　system　can　realize　asymptotic　stable　consensus.　At　last,　we　illustrate　basic　ideas　of　our　methods　by　an　example.　(C)　2013　The　Authors.　Published　by　Elsevier　Ltd.
