【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.

1前言

車聯(lián)網(wǎng)的本質(zhì)是利用現(xiàn)代無(wú)線通信技術(shù)實(shí)現(xiàn)人、車、路、云之間的協(xié)同，基于車聯(lián)網(wǎng)技術(shù)的典型應(yīng)用，如自動(dòng)駕駛、輔助駕駛、多媒體信息服務(wù)等，可以有效提升交通效率、減少交通事故。（剩余9403字）
