In a conventional sidewalk comprising a flat walking path and a projecting path, when a blind person walks on the sidewalk, the blind person must accurately detect and judge the unevenness and proceed. In particular, for unskilled walking beginners and elderly blind people, it is difficult to walk quickly due to lack of accuracy and inaccuracy in detecting with feet wearing a cane or shoes, and walking with false recognition is more likely. There are problems that can be dangerous.

On the other hand, when a traveling vehicle travels using a rail laid on a road surface as a guide, if the rail is projected on the road surface, a pedestrian may trip on the rail or hinder walking. Further, the work of laying the rail-type rail-type derivative has a disadvantage that the cost is high, and when a user or a traveling vehicle moves or changes course along the derivative, desired information such as a destination and a passing point is not obtained. There are problems such as difficulty in obtaining. Therefore, the present invention is to provide a road surface guidance device that can solve the above-mentioned conventional problems.

Next, the material W is sprayed on the road surface 1a to form a sprayed coating F.
A specific example of the thermal spraying means for forming the above will be described. In the first embodiment shown in FIGS. 2 and 3, a guide surface 5 is formed by forming a road surface induction coating with a thermal spraying device 10 for thermal spraying a material W while traveling on a road surface 1a. A pre-processing unit 13, a thermal spraying unit 14, and a post-processing unit 15 are sequentially disposed below a machine base 12 having self-propelled wheels 11, and a handle 16, a prime mover 17, a compressor 18,

And is connected so as to send a detection signal from the thermal spray coating F to the converter 34 when the grounding portion 6c contacts the thermal spray coating F. The sensor 37 is a sensor for detecting the thermal spray coating F of the guideway 5 and the special display portion of the specific guideway 8, and the sensor 38 is a sensor for detecting information of the ground child S. The sensor 38 of the sensor 7 (moving element) reads information stored in the ground element S using radio waves by a frequency modulation method. In this embodiment, an example in which a plurality of sensors are used as described above is shown. However, when a single sensor is used, the thermal sprayed coating F transmits a signal of the same type in a special display section, for example, in the form of a bar code. It becomes possible if the sensor 37 is attached so as to detect it. Alternatively, a plurality of different signals set on the thermal spray coating F may be detected in one sensor 37.

F is detected, the detection signal is converted into an audio signal by the conversion device 34, and the user is notified of the presence of the thermal spray coating F and the ground child S as sound from the speaker 32, and the information is recognized. In addition, while the switch is ON, the notification may be made only when the pedestrian comes off the thermal spray coating.

Therefore, if the user walks forward while listening to the voice, the user does not deviate from the guideway 5, and
Is to easily perform the construction by spraying a heat-resistant material W that can identify and detect the road surface derivative by the sensor 7 on the road surface as a road surface induction coating, and to walk safely without a road surface with little unevenness. I can do it. When the vehicle reaches the specific guideway 8 with the movement, the sensor 3
8 (or the sensor 37 itself) reads a pattern that causes a special reaction from the special display portion of the thermal sprayed coating F, and outputs the detection signal by voice from the speaker 32 via the conversion device 34, for example, near the intersection or the pedestrian crossing 3. In addition, the user can be notified of the specific guideway 3a of the pedestrian crossing or the target building, and road surface information such as environmental information.

Thus, the user can move the road surface 1a with the tip of the cane 6.
If the user walks so that the ground contact portion 6c abuts on the guideway 5 without tracing the guideway 5, the guideway 5 can be easily recognized without error and the user can walk safely. Therefore, even a user such as a blind person who is unfamiliar with walking can safely and easily walk with the walking stick 6 of this embodiment. Further, when it is necessary to evoke the surroundings when walking, if the alarm button 31 is pressed, a voice can be emitted from the speaker 32 at any time, which is convenient. Further, the buttons 31 are sensors 37 and 38.
