To　ensure　safety,　it　is　necessary　to　test　the　connected　vehicle　(CV)　technology　before　application.　The　goal　of　this　study　is　to　provide　a　case　reference　for　the　testing　of　the　connected　vehicle　technology.　The　connected　vehicle　technology　test　platform　is　built　based　on　the　driving　simulator.　Taking　fog　zone,　tunnel　zone,　and　work　zone　as　analysis　cases,　drivers　were　invited　to　participate　in　driving　simulation　experiments,　related　data　was　collected,　and　the　impact　of　connected　vehicle　technology　on　driving　behavior　and　safety　was　analyzed.　The　results　of　the　fog　zone　imply　that　drivers　have　a　high　degree　of　compliance　with　the　connected　vehicle　technology.　However,　it　also　increases　the　visual　workload　of　drivers　to　a　certain　extent.　The　results　of　the　tunnel　zone　indicate　that　the　connected　vehicle　technology　can　enhance　driving　safety　by　enabling　drivers　to　remain　cautious.　The　results　of　the　work　zone　demonstrate　that　the　connected　vehicle　technology　is　able　to　promote　drivers＇　ability　of　controlling　speed　and　lane-changing.　Overall,　the　results　show　that　the　connected　vehicle　technology　has　a　positive　effect　on　enhancing　driving　behavior　and　safety.　The　research　framework　and　the　development　of　the　connected　vehicle　technology　test　platform　based　on　the　driving　simulator　given　in　the　paper　are　dynamic　and　reproducible,　which　provides　a　reference　for　researchers　in　related　fields,　and　the　case　analysis　in　this　paper　enriches　the　research　of　connected　vehicle　technology.
