Guide　sign　is　an　important　traffic　management　facility　and　informs　the　drivers　of　road　network　information.　It　also　has　great　impact　on　the　smooth　flow　and　traffic　safety.　This　article　draws　on　the　construction　method　of　conventional　roads　guide　signs　system　from　Manual　on　Uniform　Traffic　Control　Devices　(MUTCD).　Based　on　the　recognizing　characteristic　and　the　information　retrieval　model　of　Chinese　drivers,　this　research　provides　the　construction　method　of　Chinese　conventional　roads　guide　signs　system　combined　with　the　feathers　of　the　Chinese　road　network　structure.　Using　this　method　to　the　typical　road　network,　the　comparison　and　analysis　of　vehicle　road　experiments　before　and　after　reconstruction　shows　this　method　can　effectively　direct　the　drivers　to　improve　the　efficiency　of　arriving　at　the　destination　and　reduce　the　probability　of　taking　the　wrong　path.　Based　on　this　effect,　it　can　be　considered　the　effectiveness　of　guide　signs　designing　is　improved.　(Programme　No:　2009BAG13A02)　©　2012　Springer　Science+Business　Media,　LLC.
