【Abstract】Three types of IoV communication network test platforms of the 5th Generation mobile communication technology（5G），EnhancedUltraHigh Throughput （EUHT）andLong-TermEvolution-VehicletoEverything（LTE-V2X）are constructedbasedontheclosedtestfield.Andfour testscenariosaredesigned，includingthefull-fieldperformancetest， dynamicandstaticperformancetest，Vehicle-to-Infrastructure （V2I）communicationperformancetestandVehicle-to-Vehicle （V2V）communication performance test.Communicationdelay，datapacketdeliveryrateandthroughputareusedas evaluation metrics toverifyandcomparativelyanalyzetheperformanceof theabove threecommunicationnetworks intypicalapplication scenarios，suchasvaryingcommuicationdistancs，diferentvehiclespeeds，V2Icommunicationuplink，downlinkandhbrid transmissionandend-to-endV2Vcommunication inreal-vehicletests.Testresults indicatethatthethreeabovenetworks generally satisfytherequirementsof IoVapplications in dynamic traffc environment，among which 5G demonstrates the superiorperformance，followedbyEUHT，butintermsofdeploymentcostandcomplexity，LTE-V2Xhasasignificant advantage.
