To　explore　the　effects　of　navigation　broadcast　wording　complexity　on　driving　behaviors,　taking　ordinary　intersections　as　an　example,　this　paper　divided　wording　complexity　into　four　levels:　,　,　and　.　The　experiment　data　were　obtained　through　driving　simulation　method　and　a　multi-dimension　indicator　system　considering　the　spatio-temporal　and　comprehensive　driving　performance　of　drivers　was　constructed.　The　temporal　and　spatial　characteristics　of　driving　behaviors　under　different　navigation　broadcast　wordings　were　studied　through　variance　analysis　and　nonparametric　test　methods,　and　the　change　law　of　comprehensive　driving　performance　was　excavated.　The　results　show　that　drivers　start　to　slow　down　from　200m　upstream　of　the　intersection;　the　effects　of　broadcast　wordings　of　four　levels　are　obviously　different　between　100m　upstream　to　100m　downstream　in　the　intersection;　under　the　guidance　of　broadcast　wording　Levels　and　,　the　stability　of　vehicle　operation　is　poor;　as　compared　with　the　comprehensive　driving　performance　under　the　guidance　of　broadcast　wording　Level　,　the　comprehensive　driving　performance　under　Levels　,　and　is　improved　by　15%,　20%　and　40%,　respectively.　©　2021,　Editorial　Department,　Journal　of　South　China　University　of　Technology.　All　right　reserved.
