The present invention relates to a road guidance system for the blind, and the invention comprises: a plurality of RFID tags (10) which are buried inside a pedestrian pavement (100) by allowing information of said pavement (100) to be contained therein, along the pavement on which Braille blocks are formed or the pavement on which forming Braille blocks is difficult; a guide robot (20) which has an RFID reader (21) for checking signals of said RFID tags (10) from said pavement (100) by passing therethrough, and an obstruction sensor (22) for sensing an obstruction ahead at a certain distance, wherein wheels (23) are positioned on both sides of the guide robot such that the guide robot advances or retreats by the driving of a motor (24); a controller (30) which checks signals from said RFID reader (21) and said obstruction sensor (22) inside said guide robot (20), converts the checked information into voice signals and outputs the voice signals, and then controls the driving of said guide robot (20); and a stick (40) which is connected such that a lower end thereof can be assembled in said guide robot (20), and is electrically connected to enable communication with said guide robot (20), thereby enabling safe loading and unloading. Particularly, the invention enables a blind person to conveniently adjust a moving speed of the guide robot by a blind person's will and to recognize, in advance, any obstructions or stairs or the like ahead, whereby the invention enables safer walking guidance and prevents collisions.
