The　change　of　space　environment　at　the　tunnel　entrance　which　the　light　changes　from　bright　to　dark　will　lead　to　frequent　traffic　accidents.　To　explore　whether　the　connected　vehicle　environment　will　improve　the　driving　performance　and　traffic　safety　at　the　tunnel　entrance,　this　paper　first　of　all　designed　a　driving　simulation　experiment　and　provided　driving　aids　through　the　Human-Machine　Interface　(HMI).　Then　35　drivers　were　invited　to　take　a　driving　simulation　under　two　different　driving　conditions:　traditional　driving　environment　(HMI-OFF)　and　connected　vehicle　environment　(HMI-ON).　Finally,　the　effectiveness　and　safety　of　HMI　can　be　evaluated　from　two　aspects　of　driver　response　efficiency　and　deceleration　process,　and　further　explore　the　causes　of　driving　behavior　changes　by　Cox　model.　The　results　show　that　the　driver＇s　response　efficiency　and　deceleration　behavior　are　both　improved　in　the　connected　vehicle　environment.　The　warning　information　provided　by　in-vehicle　HMI　enables　the　driver　to　know　the　road　conditions　ahead　earlier　and　adjust　the　speed　through　more　gentle　acceleration　so　that　the　vehicle　can　enter　the　tunnel　at　a　more　stable　speed.　At　the　same　time,　there　are　significant　differences　in　the　brake-movement　time　of　different　driving　ages,　which　the　brake-movement　time　increases　with　the　driving　age.　This　indicates　that　experienced　drivers　usually　adopt　a　soft　way　to　adjust　the　speed,　so　that　the　vehicle　speed　change　process　is　more　stable　on　the　premise　of　ensuring　driving　safety,　so　as　to　avoid　the　potential　danger　brought　by　drastic　speed　change.　In　this　paper,　a　validity　evaluation　method　based　on　survival　analysis　is　proposed　for　tunnel　entrance　scenarios,　which　provides　a　reference　for　the　realization　of　connected　vehicle　evaluation.
