This　study　aims　to　provide　a　reference　for　improving　the　guide　sign　technical　standards　of　China,　considering　the　differences　between　the　form　of　freeway　exit　gore　signs　in　technical　specifications　in　China　and　the　developed　countries,　represented　by　the　United　States.　The　study　also　seeks　to　investigate　the　utility　of　different　forms　of　exit　gore　signs.　In　this　study,　two　kinds　of　exit　gore　signs　were　designed　to　form　four　guide　sign　schemes　located　in　r-shaped　and　Y-shaped　exits,　and　the　signs　were　implemented　through　way-finding　experiments　by　the　driving　simulation　to　obtain　micro-driving　behavior　data.　Then,　the　factor　analysis　method　was　applied　to　obtain　the　comprehensive　factor　score,　which　was　defined　as　the　＇exit　action　parameter.＇　Based　on　this　parameter,　three　evaluation　indexes　of　strength　value,　change　rate,　and　action　position　were　selected　to　compare　the　effects　of　the　various　exit　gore　sign　forms　under　different　exit　forms.　The　results　demonstrate　that　the　strength　value　and　action　position　of　the　simplified　form　are　found　to　be　better　than　those　of　the　national　standard　form　for　both　r-shaped　and　Y-shaped　exits.　However,　the　change　rate　of　the　simplified　form　is　inferior　to　that　of　the　national　standard　form　for　the　r-shaped　exit,　and　no　difference　is　observed　for　the　Y-shaped　exit.　The　evaluation　indicators　vary　for　different　exit　forms.　The　exit　gore　sign　with　simplified　form　helps　to　promote　the　strength　value　and　action　position　of　the　exit　action　parameter　and　exhibits　a　better　comprehensive　effect　for　the　Y-shaped　exit.　Therefore,　it　is　recommended　that　the　simplified　form　should　be　applied　in　exit　gore　signs　in　Y-shaped　exits.　©　2020,　Editorial　Department　of　China　Journal　of　Highway　and　Transport.　All　right　reserved.
