Drivers＇　behavior　characteristics　cannot　be　ignored　in　designing　freeway　interchange　facilities　in　order　to　improve　traffic　safety.　This　paper　conducted　a　field　experiment　in　Qingyin　expressway.　Four　freeway　interchanges　from　K571+538　to　K614+932　with　relatively　low　volume　were　selected,　and　12　qualified　drivers,　6　car　test　drivers　and　6　truck　test　drivers,　were　driving　vehicles　according　to　the　driving　program.　GPS　and　eye-tracking　instrument　were　employed　to　record　running　speed,　real-time,　running　track,　fixation　point,　and　so　forth.　Box-plot　graphs　and　Student＇s　t-test　were　used　to　analyze　the　12　data　sets　of　driver＇s　fixation　on　exit　guide　signs.　Speed-distance　curves　of　effective　11　data　sets　were　plotted　to　examine　the　test　drivers＇　behavior　in　diverging　area　and　merging　area.　The　results　indicated　that　(1)　drivers　recognize　the　exit　direction　signs　in　170　m-180m　advanced　distance;　(2)　the　diverging　influence　area　is　1000　m　upstream　of　the　diverge　point,　and　the　merging　influence　area　is　350　m　downstream　of　the　merge　point;　(3)　NO　OVERTAKING　sign　is　recommended　to　be　placed　at　350　m　upstream　of　the　diverge　point.　The　results　can　provide　guidance　for　the　design　of　freeway　interchange　facilities　and　management　in　order　to　improve　traffic　safety.
