In　this　paper,　we　develop　a　coordinated　traffic　responsive　ramp　control　strategy,　under　which　traffic　density　of　freeway　network　can　realize　balanced.　Firstly　we　propose　a　hybrid　switched　model　of　freeway　network　by　using　CTM;　furthermore,　we　obtained　the　balanced　density　in　free　flow　state　case;　then,　on　this　basis,　we　design　a　feedback　control　law,　under　which　the　proposed　control　system　can　realize　asymptotic　stable;　at　last,　we　conduct　a　simulation　on　Beijing　third　ring　freeway　network.　Simulation　results　show　that　the　proposed　ramp　control　strategy　compares　favorably　against　the　well-known　ALINEA　control　strategy　in　increasing　the　usage　of　freeway　network　and　reducing　delay　of　vehicles　in　on-ramps.　©　2017　ICIC　International.
