In　China,　the　chevron　aligmnent　sign　(a　vertical　rectangle　with　a　white　arrow　and　border　on　a　blue　background)　has　been　widely　used　on　roadway　curves　to　provide　advance　warning　and　positive　guidance　through　curves.　Chevron　alignment　signs　are　retroreflective　guidance　devices　installed　near　roadway　edges　indicating　roadway　alignment.　But　the　effects　of　the　China　chevron　alignment　signs　on　drivers＇　eye　movements,　driving　performance,　and　stress　have　rarely　been　studied.　Few　guidelines　have　been　established　for　the　size　and　application　of　chevron　signs　in　China.　This　paper　reports　on　a　driving　simulator　experiment　that　measured　the　data　on　drivers＇　eye　movements,　inputs,　and　electrocardiograms　through　an　urban　expressway　ramp　with　and　without　chevron　aligmnent　signs.　A　comparative　analysis　was　conducted　to　examine　the　changes　in　drivers＇　eye　movements,　driving　performance,　and　heart　rates.　Results　show　that　drivers　pay　more　attention　to　the　roadside　near　chevrons;　they　are　also　more　relaxed　and　tend　to　drop　their　speed　more　when　chevrons　are　present.　This　finding　indicates　that　chevron　alignment　signs　do　provide　advance　warnings　and　positive　guidance　and　make　drivers　tend　to　drop　speed　more　through　curves,　which　improves　safety　and　uniformity　in　curve　delineation　on　urban　expressway　ramps.
