Several　studies　have　researched　the　effect　of　dynamic　message　signs　(DMSs)　on　the　driving　safety　in　work　zones.　However,　only　a　few　studies　have　examined　the　design　of　DIM　control　strategies　in　work　zones.　The　purpose　of　this　study　is　to　investigate　the　effects　of　DMS　control　strategies　on　driving　decisions　and　behaviors　and　to　improve　the　driving　safety　in　work　zones　by　changing　the　content　and　placement　of　DMSs.　In　this　study,　five　control　strategies　are　proposed　by　combining　five　DMSs　with　different　contents　(＂change　lane＂　versus　＂go　straight＂).　A　total　of　32　participants　participated　in　this　study.　Each　participant　drove　in　five　scenarios　in　a　high-fidelity　driving　simulator　corresponding　to　strategies　1-5.　The　results　show　that　the　control　strategies　have　a　significant　effect　on　drivers＇　decisions　and　behavior　(e.g.,　the　driving　speed,　acceleration,　and　lateral　placement).　All　strategies　reduce　the　drivers＇　speeds　and　improve　their　control　stability　and　compliance.　After　conducting　analytic　hierarchy　process　(AHP)　analysis,　strategy　2　was　removed　because　the　approaching　speed　exceeded　the　speed　limit.　The　weight　vectors　of　strategies　1,　3,　4,　and　5　under　free-flow　traffic　and　traffic　jam　conditions　are　Upsilon(free-flow　traffic　)=　[0.25,0.28,　0.17,　0.23]　and　Upsilon(traffic　jam)　=　[0.17,0.28,0.2,0.3],　respectively.　These　results　show　that　strategy　4　is　not　suitable　for　free-flow　traffic　in　work　zones,　while　strategies　5　and　3　are　suitable　for　traffic　jams　in　work　zones.　Strategy　3　is　suitable　for　both　free-flow　traffic　and　traffic　jams.　＇I　he　first　occurrence　of　a　decision　sign　that　contains　lane　change　content　is　key　to　the　driver＇s　decision;　in　addition,　the　position　of　signage　with　such　information　should　gradually　be　moved　closer　to　work　zones　with　increasing　traffic　flow.
