Raised　pavement　markers　(RPMs)　are　common　traffic　safety　facilities　in　freeway　tunnels,　which　play　an　important　role　in　preventing　and　reducing　traffic　accidents.　A　driving　simulator　experiment　was　conducted　to　analyze　the　impact　of　RPMs　from　the　driver＇s　perspective　to　study　the　effect　of　RPMs　on　freeway　extra-long　tunnels　on　the　drivers.　The　effect　of　RPMs　in　freeway　extra-long　tunnels　was　also　evaluated　based　on　micro　driving　behavior　data　and　eye　movement　data.　Two　RPMs　alternatives　(RPMs-B:　RPMs　installed　on　the　edge　line　and　the　maintaining　roadway;　RPMs-C:　RPMs　installed　on　the　lane　and　edge　lines)　were　designed,　and　their　performance　was　compared　with　a　tunnel　without　RPMs　(RPMs-A).　Thirty-two　licensed　drivers　were　recruited　to　gather　fine-grained　data　on　driving　behavior　and　eye　movement.　Seven　measurement　indicators,　such　as　average　speed,　acceleration　and　lateral　position,　were　selected　to　build　the　evaluation　indicator　system,　and　repeated-measures　ANOVA　was　used　to　explore　the　significance　level　and　effect　size　of　each　indicator.　Finally,　the　effects　of　the　three　RPM　alternatives　were　compared　using　a　fuzzy　comprehensive　evaluation　model　based　on　the　entropy　weight　method.　The　results　show　that　RPMs　significantly　affect　the　driver＇s　behavior,　psychology,　and　physiology,　and　have　different　degrees　of　practical　significance.　The　psychological　and　physiological　load　on　the　driver　is　reduced,　anxiety　is　relieved,　and　subjective　comfort　is　found　to　be　good.　The　speed　control　ability　is　enhanced,　the　perception　and　control　level　of　the　vehicle＇s　lateral　position　are　increased.　Further,　the　vehicle　driving　is　found　to　be　comparatively　more　stable.　However,　RPMs　in　the　curved　section　of　the　tunnel　significantly　increased　the　average　speed　and　risk　of　accidents.　The　results　of　the　fuzzy　comprehensive　evaluation　show　that　RPMs-C　is　the　best　alternative　for　the　entire　tunnel　and　the　curved　and　middle　sections;　i.e.,　RPMs　are　the　best　alternative　to　lane　boundaries　and　edge　lines　along　both　sides　of　the　tunnel.　The　results　of　this　study　provide　a　solution　for　the　evaluation　and　optimization　of　tunnel　safety　facilities　and　lay　a　foundation　for　the　formation　of　tunnel　safety　facilities　to　set　safety　guidelines.　©　2020,　Editorial　Department　of　China　Journal　of　Highway　and　Transport.　All　right　reserved.
