The　cooperative　vehicle　infrastructure　system　(CVIS)　has　been　regarded　as　an　advanced　technology　and　a　research　focus　in　the　field　of　intelligent　transportation.　Countries　worldwide　are　committed　to　the　research　and　development,　testing,　demonstration　applications,　and　utility　evaluation　of　CVIS.　However,　the　service　object　of　CVIS　is　the　driver;　therefore,　it　is　of　great　importance　to　study　the　driver＇s　subjective　acceptance　of　CVIS　and　its　influencing　factors　before　CVIS　is　officially　applied.　The　basic　technology　acceptance　model　(TAM)　was　used　as　the　theoretical　framework　in　this　study.　Using　the　four　basic　variables　(perceived　usefulness,　perceived　ease　of　use,　attitude,　and　intention),　as　well　as　four　extended　variables　(quality　of　warning　service,　distraction　perception,　personal　innovation,　and　trustworthiness),　an　extended　TAM　was　used　to　analyze　the　driver＇s　subjective　acceptance　of　CVIS　and　its　influencing　factors.　First,　an　online　CVIS　questionnaire　was　sent　to　392　drivers.　Second,　Cronbach＇s　α　and　confirmatory　factor　analysis　were　used　to　inspect　the　reliability　and　validity　of　the　questionnaire.　Finally,　path　analysis　was　used　to　explore　the　driver＇s　acceptance　of　CVIS　and　its　influencing　factors.　The　results　show　that　the　relationship　among　the　basic　TAM　variables　is　consistent　with　the　basic　model　assumptions.　The　quality　of　the　CVIS　warning　service　indirectly　affects　usage　intentions　through　perceived　usefulness,　perceived　ease　of　use,　and　attitude.　The　driver＇s　distracted　perception　of　CVIS　has　no　negative　effect　on　his　attitude　and　usage　intention.　The　driver＇s　personal　innovation　not　only　directly　affects　the　usage　intention,　but　also　indirectly　influences　usage　intention　through　attitude.　The　driver＇s　trust　in　CVIS　is　a　direct　influencing　factor　of　usage　intention,　and　indirectly　affects　usage　intention　through　other　variables.　The　results　contribute　to　understanding　the　driver＇s　acceptance　of　CVIS　and　its　influencing　factors　and　provide　theoretical　support　for　the　design　of　CVIS.　©　2021,　Editorial　Department　of　China　Journal　of　Highway　and　Transport.　All　right　reserved.
