The roads constructed during the years of steep economic growth are aging all at the same time, as a result, local communities are showing growing interest in the improvement of the efficiency and quality of road maintenance and administration. This paper first describes the basic testing attaching RFIDs (Radio Frequency IDentification) to road facilities and then discusses the implementation methodology and effect of the road maintenance and administration support system through the field experiment.. 䋱䋮䈲䈛䉄䈮㩷. ࠣ࡞ࡊ࠙ࠚࠕ ).+$$5 ߩ㐿⊒ߦ⌕ᚻએ᧪. 㜞ᐲᚑ㐳ᦼߦᢛߐࠇߚ〝ߪ৻ᢧߦ⠧ൻ. 〝⛽ᜬ▤ℂߦ߅ߌࠆ⊒ᵈ⠪ߢࠆⴕߣᆔ⸤. ߩᤨᦼࠍㄫ߃ߐࠄߦߪⴕౣ✬ߦࠃࠆ▤ℂ. ᬺ⠪㑆ߩᖱႎવ㆐ߩല₸ൻߣ⾰ะߦߟ. ࠛࠕߩᐢၞൻߦࠃߞߡ〝⛽ᜬ▤ℂᬺോߩ. ߡታ⸽⊛ߥขࠅ⚵ߺࠍⴕߞߡ߈ߚ=?=?=?. ല₸ൻߣ⾰ะߦኻߔࠆၞߩ㑐ᔃߪ㜞߹ߞߡ. ߎࠇࠄߩขࠅ⚵ߺࠍ⊒ዷߐߖ〝ߩ᭽▤ߥޘ. ࠆߊࠊ߃ߡኙ಄ߢࠆጤᚻ⋵ߪⓍ㔐.
