The　eight-lane　freeway　resulting　from　reconstruction　and　expansion　typically　exhibits　short　distances　between　interchanges　and　a　wide　road　section.　Nonetheless,　the　absence　of　specific　guidelines　for　the　placement　of　guide　signs　in　dense　interchange　sections　of　the　eight-lane　freeway　results　in　inadequate　design,　thereby　impeding　drivers＇　ability　to　read　and　comprehend　the　signs.　To　tackle　this　issue,　the　study　employs　two　interchanges　2.48　km　apart　on　the　Jinan-Qingdao　Freeway　as　a　case　study.　Four　optimization　schemes　for　guide　signs　are　developed　based　on　drivers＇　information　requirements　and　compared　with　the　current　guide　sign　design　scheme.　Thirtynine　drivers　were　recruited　to　gather　detailed　driving　behavior　indicators　via　a　driving　simulation　experiment.　The　impact　of　the　guide　sign　optimization　scheme　on　driving　behavior　is　analyzed,　and　the　overall　effects　are　evaluated　using　the　non-integer　rank　RSR　method.　This　study　aims　to　identify　an　optimal　approach　to　guide　sign　design　for　dense　interchange　sections.　The　results　indicate　that　the　impact　of　guide　signs　in　dense　interchange　sections　on　drivers　is　primarily　concentrated　between　the　two　interchanges.　Specifically,　the　addition　of　a　2.5　km　exit　advance　sign　enhances　drivers＇　speed　regulation　level,　the　inclusion　of　navigation　voice　improves　operational　stability,　and　the　presence　of　pavement　words　at　exit　diversion　locations　enhances　psychological　comfort　for　drivers.　By　considering　the　comprehensive　effectiveness　of　each　optimization　scheme,　it　is　evident　that　schemes　5　and　2　exhibit　superior　optimization　effects.　This　suggests　that　providing　advanced　notice　of　exit　information　in　dense　interchange　sections　of　eight-lane　freeways　is　an　effective　measure　to　enhance　freeway　service　levels　and　ensure　driving　safety.　It　is　recommended　that　under　the　conditions　of　insufficient　interchange　spacing,　the　information　of　interchange　exits　should　be　forewarned　in　advance.　Additionally,　auxiliary　navigation　voice　and　pavement　words　should　be　employed　to　enhance　drivers＇　information　perception　levels,　thereby　mitigating　the　risk　of　missing　exits　due　to　limited　reaction　time.　This　paper　serves　as　a　significant　reference　for　informing　the　optimal　configuration　of　guide　signs,　thereby　contributing　to　the　meticulous　development　of　standardized　specifications.
