To　meet　guidance　demand　of　indirect　reached　freeway　in　road　network　developed　areas,　and　to　solve　several　key　design　issues　including　road　name,　place　name　information　quantity　threshold　and　road　name　information　layout,　reaction　time　data　was　obtained　through　the　static　cognitive　experiment　with　road　name　and　place　name　combined　cognitive　tasks.　The　conclusion　based　on　repeated　measures　analysis　of　variance　(ANOVA)　is　dawn　the　quantity　of　place　name　and　road　name　have　a　significant　effect　on　the　drivers＇　reaction　time,　and　have　interactions　between　them　while　the　road　name　information　layout　has　no　significant　effect.　The　quantity　threshold　of　the　place　name　under　the　condition　of　1-4　road　names　was　further　studied,they　were　6,　6,　5　and　4　under　the　conditions　of　single,　double,　three　and　four　road　name　respectively.　Results　show　that　the　numbers　of　road　and　place　name　should　not　exceed　the　threshold　as　the　advance　guide　sign.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
