Abstract：Inorder tocarryout adaptive traffic lightadjustment according to traffcflowconditions，maximize traffic eficiencydtellttoffelltrod MRFOalgorithmisproposed.Thetrafficlightintellgentcontrolframework basedonfield-programmablegatearray（FPGA）is constructedbyanalyzingtheactualdemandoftraffclightitellgentcontrol.Basedonteintellgentcontrolframework，the minimumobjectivefunctionandrelatedconstraintconditionsofthedelaytimeofalltraffcflowdirectionvehiclesatthetraffic intersectionareconstructedaccording totheactualtraffcoperation.TheMantarayforagingoptimization（MRFO）algorithmis usedtoiterativelyoptimizetheobjective functionofintellgentcontrolof traffclightsundertheconditionofsatisfying constraints，andtheoptimalcontrolstrategyisobtainedtorealizeintellgentcontroloftraffclights.Afterexperimental verification，thismethodcanrealizelowdelaylevelwithlesstrainingsamplesandhighlyeficient.Itcanalsoadaptivelyadjust thesignallightdurationbasedonthetraffcflowatintersections，ensuringthevehiclepassngrateofover96%.Itffectively provesthatthemethodcanaleviateroadcongestion，reduce theocurenceof safetyaccidents，and therebyenhance traffic safetylevel.Its effectiveness isverified.
